 others are hermaphrodites, each one of the fpecies

 by contad \ but many of the female fiflies caft 

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

 the male fifli is near at hand, who fhedding his 

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

 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 fît 

 upon to hatch their young. Quadrupeds that are 

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

 cies of the toad brought from Surinam, whofe 

 back is full of fmall cavities, in each of which 

 is found a young toad ; fome of the young
