 2 8 |     discharge water through their gills, they suck the air out of

 9 16|           so far as observed, has gills. It is called the tadpole.~

12 16|      reason why some animals have gills, others lungs, but none

18 22|        situated relatively to the gills we must employ dissections,
19 22|           to the centre where the gills all join. This then is the
