 are males and females of the fame Ipecies 5 

 others are hermaphrodites^ each one of the fpecies 

 partaking of both fexes, as do mod forts of 

 fnails, &c. Mofc animals on the land generate 

 by conta6t ; but many of the female fifhes caft 

 their eggs (called hard roe) in the water, when 

 the male fiih is near at hand, who fhedding his 

 feed (called foft roe) in the water at the famé 

 time, it mixes with, and gives life to the eggs, 

 without his touching the female. The whole 

 race of birds increafes from eggs, which they fit 

 upon to hatch, their young. Quadrupeds that are 

 hairy, all bring forth their young alive -, as do 

 alfo fome few that are fcaly, as the Armadilla 

 kind : but all animals of the Lizard kind, whe- 

 ther of the land or water, or frequenting both, 

 from the Crocodile down to the fmalleft fpecies^ 

 lay eggs, which are hatched by the warmth of 

 the fun. Some fiflies bring forth their young 

 alive. A remarkable, and, I believe, fingulaf 

 way of generation is obferved in a large Ipe- 

 cies of the toad brought from Surinam, whofe 

 back is full of fmall cavities, in each of which 

 is found a young toad j fome of the young
