in proportion, from.the finer parts of flowers. 
Animals covered with fcales are more produc- 
tive than thofe covered with hair, probably be- 
-caufe, by perfpiring lefs, they accumulate.a greater 
number of organic molecules. 
If, inftead of collecting in the organs of gene- 
‘ration, the molecules are carried to other parts 
of the animal, they there form minute living ani- 
‘mals, as tenie and a/fcarides, worms fometimes 
inhabiting the inteftines, the liver, and the fino- 
fities of the brain. 
‘Thus does the-theory of M. a Buffon explain 
thefe phenomena, and fome others, which, for 
the fake of brevity, I fhall omit. Wifhing this 
theory, the offspring of -his fertile genius, to be 
adopted by nature, he recurs to the feminal fluids 
of animals and the infufions of plants, becaufe in 
‘both, according to his opinion, are organic mo- 
Jecules clearly exhibited under the form of glo- 
bular, ovular, or other fhaped.corpufcula, en-

This laft trait of M. de Buffon’s theory 
proves that it refts entirely on the facts related by
