^5© ANIMALCULA OF INFUSIONS* L 



lifhed page 428 of the Palingenefie. ' AH the 



* changes are made by imperceptible degrees, and 

 ' without the animalcule or revolving machine 



* changing its place. At laft the motion is ac- 

 ' celerated ; and where the fphere appeared even, 

 ' you begin to fee two crofs divifions, as on the 

 ' hufk of chefnuts ready to open ; a little after- 



* wards the animal is agitated, and then divides 

 ' into four animalcula, perfectly fimilar, but fmall- 

 «er.' 



An important remark "is made in this letter, 

 which you will not fail to notice in your new 

 differtation. M. de Sauflure fupplies Mr Need- 

 ham's defe£live information on his difcovery. 

 ^ Doubtlefs, in four years which have paffed 

 ^ fmce I communicated this obfervation to Mr 

 ^ Needham, he mufl have forgot that I conftant- 

 ' ly obferved the parts of the divided animalcule 



* become as large as the whole which they had 

 ' compofed ; fo that the fame conftancy and uni- 



* formity are preferved in thefe generations as in 

 ' the reft of nature.' How much have I myfelf 

 infifted on the conftant uniformity of this new 

 order of propagation. We may almoft fuppofe, 

 Mr Needham has taken that part only of the dif- 

 covery which he mentions, and feemed favour- 

 able to his theory.

 fervations, my dear correfpondent, with a gene-
