  1   I,  3 |            the upper region impart heat to the earth and its neighbourhood.
  2   I,  3 |            appreciably near to the heat of the stars, nor to the
  3   I,  3 |    dissolve any formation by their heat and so prevent clouds from
  4   I,  3 |            to it, and so generates heat. From another point of view
  5   I,  3 |           for fire is an excess of heat and a sort of ebullition;
  6   I,  3 |          that fills it.~As for the heat derived from the sun, the
  7   I,  3 |        treatise about sense, since heat is an affection of sense,
  8   I,  3 |          of terrestrial warmth and heat. For a motion that is to
  9   I,  3 |       sufficient degree. That most heat should be generated where
 10   I,  3 |        This then is one reason why heat reaches our world. Another
 11   I,  4 |      pressure, since naturally all heat tends upwards.~When the
 12   I,  9 |           sun’s rays and the other heat from above, and rises. But
 13   I,  9 |            and rises. But when the heat which was raising it leaves
 14   I,  9 |           vapour cools because its heat is gone and because the
 15   I,  9 |            is always raised by the heat and descends to the earth
 16   I,  10|       condensed into water and the heat is not so great as to dry
 17   I,  10|         watery places, so that the heat that is raising it, bearing
 18   I,  10|           cold and so quenches the heat of the evaporation. But
 19   I,  10|        north wind concentrates the heat by a sort of recoil, so
 20   I,  10|         the north winds quench the heat before any considerable
 21   I,  11|       country. For a great deal of heat is still present and unless
 22   I,  11|          in it a great deal of the heat which caused the moisture
 23   I,  12|         and in warm countries; the heat is greater and it thrusts
 24   I,  12|    concentrated by the surrounding heat and causes the cloud to

 27   I,  14|            the causes are cold and heat, which increase and diminish
 28  II,  2 |         that moisture, even if its heat made all the water in the

 31  II,  3 |           exposed to fire contains heat potentially, as we see in
 32  II,  3 |         when it has cooled and the heat and moisture have evaporated
 33  II,  3 |            to different degrees of heat it assumes various kinds
 34  II,  4 |     approaches, it draws up by its heat the moist evaporation: when
 35  II,  4 |         great quantity of fire and heat in the earth, and the sun
 36  II,  4 |          is being dried by its own heat and that from above and
 37  II,  4 |     present and wind prevails; the heat is continually being thrown
 38  II,  5 |          dissipates by its greater heat the lesser heat contained
 39  II,  5 |            greater heat the lesser heat contained in the evaporation.
 40  II,  5 |          sharp frost: or excessive heat wastes it. In the intermediate

 42  II,  5 |            earth, dried by its own heat and that of the sun, smokes
 43  II,  5 | evaporation under the influence of heat.~The question is sometimes
 44  II,  5 |        solstice. (For the greatest heat is developed not when the
 45  II,  5 |            the north, but when its heat has been felt for a considerable
 46  II,  5 |            parts requiring greater heat to melt them. So they blow
 47  II,  5 |          we meet with no excessive heat or cold in the direction
 48  II,  5 |           the other because of the heat.~But it is the sea which
 49  II,  6 |        earth and is exposed to the heat of the sun and the earth
 50  II,  8 |           seasons. Summer with its heat and winter with its frost
 51  II,  8 |      interposed, but the light and heat of the sun has not quite
 52  II,  9 |       colder on the side where the heat escapes to the upper region
 53  II,  9 |        part of the cloud.) Now the heat that escapes disperses to
 54  II,  9 |          wanton.~The view that the heat of the sun’s rays intercepted

 59  IV,  1 |           instances. In every case heat and cold determine, conjoin,
 60  IV,  1 |           the peculiar and natural heat in any moist subject by
 61  IV,  1 |          moist subject by external heat, that is, by the heat of
 62  IV,  1 |     external heat, that is, by the heat of the environment. So since

 64  IV,  1 |   everything in as far as it lacks heat is cold, both heat and cold

 69  IV,  1 |           water contain but little heat and it has no power, but
 70  IV,  1 |           cold is greater that the heat of the air and so is not
 71  IV,  1 |            or hot putrefy, for the heat in the air being less than
 72  IV,  1 |           the motion set up by the heat in the air is weaker than
 73  IV,  1 |     putrefying bodies, because the heat that has been secreted,
 74  IV,  2 |         these concoction is due to heat; its species are ripening,
 75  IV,  2 |       which the natural and proper heat of an object perfects the
 76  IV,  2 |           itself. It is the proper heat of a thing that sets up
 77  IV,  2 |        primary cause is the proper heat of the body. In some cases
 78  IV,  2 |          what is determined by the heat connatural to the object,
 79  IV,  2 |          they show that the proper heat has got the better of the
 80  IV,  2 |          hotter, for the action of heat is to make things more compact,
 81  IV,  2 |        state due to lack of proper heat, that is, to cold. That
 82  IV,  3 |     various modes in which natural heat and cold perfect the matter

 84  IV,  3 |           due to a lack of natural heat and its disproportion to
 85  IV,  3 |            due either to defect of heat or to excess of the matter
 86  IV,  3 |            to things because their heat has not got the mastery

 88  IV,  3 |     general, a concoction by moist heat of the indeterminate matter
 89  IV,  3 |   frying-pan is broiled: it is the heat outside that affects it
 90  IV,  3 |          is drawn out of it by the heat in the liquid outside. Hence
 91  IV,  3 |     themselves, since the external heat gets the better of the internal:
 92  IV,  3 |          internal: if the internal heat had got the better it would

 98  IV,  3 |         conditions is realized the heat in the surrounding liquid
 99  IV,  3 |          concoction by dry foreign heat. Hence if a man were to
100  IV,  3 |            it were due, not to the heat of the liquid but to that
101  IV,  3 |         end the agent has been dry heat. Hence the outside is drier
102  IV,  3 |             for it is difficult to heat the inside and the outside
103  IV,  3 |        medium and the agent is the heat of the body. So, too, certain
104  IV,  3 |    broiling proper through lack of heat due to deficiency in the
105  IV,  3 |        then we should get too much heat for no effect to be produced,
106  IV,  5 |            takes place by means of heat or cold, and the quality
107  IV,  5 |      presence or by the absence of heat or cold; but that which
108  IV,  5 |         but not in the same way as heat does, but by collecting
109  IV,  5 |       collecting and concentrating heat.~The subjects of drying
110  IV,  5 |         the agent in both cases is heat, either internal or external.
111  IV,  5 |      separately it is the internal heat that dries them. It carries
112  IV,  5 |            but the agent is always heat, either internal or external,
113  IV,  5 |    moisture in vapour. By external heat I mean as where things are
114  IV,  5 |      boiled: by internal where the heat breathes out and takes away
115  IV,  6 |            the agent is either dry heat or cold. Hence those of
116  IV,  6 |           the bodies solidified by heat or cold which are soluble
117  IV,  6 |          owing to the departure of heat; so it will clearly be dissolved
118  IV,  6 |            by the entry into it of heat: cold, therefore, must be
119  IV,  6 |            and in a way different. Heat acts by drawing off the
120  IV,  6 |            acts by driving out the heat, which is accompanied by
121  IV,  6 |       solidify by the departure of heat melt by heat when it enters
122  IV,  6 |          departure of heat melt by heat when it enters into them
123  IV,  6 |        gone off in vapour with the heat, like iron and horn, cannot
124  IV,  6 |      dissolved except by excessive heat, but they can be softened-though
125  IV,  6 |        which are solidified by dry heat some are insoluble, others
126  IV,  7 |          the air into water as the heat in the oil is dissipated.
127  IV,  7 |       operation is different. Both heat and cold thicken it, but
128  IV,  7 |           horn, can be softened by heat, others, like pottery and
129  IV,  7 |       solidified by cold. When the heat in leaving them has caused
130  IV,  7 |            for moisture. Therefore heat does not dissolve them (
131  IV,  7 |          what is solidified by dry heat). But iron is melted by

133  IV,  7 |           be melted or softened by heat. (For the same reason it
134  IV,  8 |          that bodies are formed by heat and cold and that these
135  IV,  8 |        fashion bodies that we find heat in all of them, and in some
136  IV,  8 |          in some cold in so far as heat is absent. These qualities,
137  IV,  8 |     solidify, melt, be softened by heat, be softened by water, bend,
138  IV,  8 |         brought into this state by heat, others by cold. Heat does
139  IV,  8 |           by heat, others by cold. Heat does this by drying up their
140  IV,  8 |          cold by driving out their heat. Consequently some bodies
141  IV,  8 |        moisture, some by defect of heat: watery bodies by defect
142  IV,  8 |         watery bodies by defect of heat, earthy bodies of moisture.
143  IV,  8 |       solidified through defect of heat are melted by heat, e.g.
144  IV,  8 |       defect of heat are melted by heat, e.g. ice, lead, copper.
145  IV,  8 |           not watery, but in which heat and earth preponderate,
146  IV,  9 |           by the agency of burning heat. Bodies that give off fumes
147  IV,  9 |           by the agency of burning heat. Hence they do not moisten
148  IV,  9 |            the influence either of heat or of both heat and cold;
149  IV,  9 |          either of heat or of both heat and cold; for we find that
150  IV,  10|     liquids which are thickened by heat are a mixture. (Wine is
151  IV,  10|        more apt to be thickened by heat and less apt to be congealed
152  IV,  10|         cold. For it contains much heat and a great proportion of
153  IV,  10|            are thickened either by heat or by cold consist of more
154  IV,  10|    hoar-frost. Those solidified by heat are of earth, e.g. pottery,
155  IV,  10|      bodies are solidified by both heat and cold. Of this kind are
156  IV,  10|           by the privation both of heat and of the moisture which
157  IV,  10|    moisture which departs with the heat. For salt and the bodies
158  IV,  10|      moisture only, ice by that of heat only, these bodies by that
159  IV,  10|      formed by solidification. The heat is driven out of it by the
160  IV,  10|          cold which drives out the heat, which, as it leaves the
161  IV,  10|         they admit of softening by heat, e.g. iron and horn.~Now
162  IV,  10|         for they are all melted by heat. Of water, too, are some
163  IV,  10|         some admit of softening by heat, the rest give off fumes
164  IV,  10|       leaving it together with its heat.~
165  IV,  11|         wine) they contain foreign heat. Bodies consisting of earth,
166  IV,  11|           are commonly hot because heat was active in forming them:
167  IV,  11|            a body contains foreign heat as water does when it boils
168  IV,  11|          latter, too, has acquired heat from the ashes, for everything
169  IV,  11|        burnt contains more or less heat. This explains the generation
170  IV,  11|       putrefying body contains the heat which destroyed its proper
171  IV,  11|         which destroyed its proper heat.~Bodies made up of earth
172  IV,  11|      existence from concoction and heat, though some, like the waste
173  IV,  11|     highest temperature by foreign heat; for the most solid and
174  IV,  11|           coldest when deprived of heat and most burning after exposure
175  IV,  12|           that form from milk.~Now heat and cold and the motions
176  IV,  12|            go to make up. Cold and heat and their motion would be
