54 SEMINAL VERMICULI. ify 
‘ refervoirs of the feminal fluid. Apparently. 
“they are excluded, but in thofe feminal fluids: 
* that have acquired a certain degree of perfec- 
* tion, which happens only at the age of pu- 
‘berty, it would be a moft curious experiment’ 
“to try whether infufion animalcula would live. 
*in fome feminal fluids: And in the fame man-’ 
“ner, whether the vermiculi would live in infu- 
*fions. Above all, the temperature of the place 
‘and the fluid would need to be regulated. Who 
¢ can fay that this experiment, which is certainly 
¢ new, will not fucceed? I communicate all my 
€ ideas to you. My maxim is to defpair of no- 
‘thing in natural hiftory. Why fhould we fay a 
‘ thing is impoffible, becaufe we have not feen it 
‘fucceed? ‘This maxim is founded on our pro- 
¢ found ignorance of the fecrets of nature, and on 
‘the deviations fhe in many cafes feems to make 
© from her ordinary courfe, Every where is an 
¢ univerfal latitude feen, yet I am ignorant of 
* the limits.. They can be difcovered by experi- 
*ment alone: and how much may experiments 
‘of 
ties which we behold arife from accidents that individuals 
were fubjected to in the mof remote antiquity. Why. 
fhould it be more difficult to admit variety in the races of 
men than push any other animated being iohabiaiag the 
globe?
