filaments. Some of thefe tails were fo long and 

 fo thin, that they had no proportion to the bo- 

 dies, which were always more or lefs embarraf- 

 fed, according to the length of the threads or 

 tails. When the tail was long, the angle of the 

 vibratory motion was increafed ; and, when the 

 tail was fliort, the progreffive motion was more 

 confpicuous.

I continued my obfervations, almoft without 

 interruption, for 14 hours, and I difcovered,that 

 the length of the tails or threads gradually dimi- 

 nifhed, and became fo thin and delicate, that 

 their extremities fuccefTively ceafed to be vifible ; 

 and at laft the whole difappeared. The horizontal 

 vibrations of the globules then ceafed, and their 

 progreffive motion was dired:, though they ftill 

 had verticle ofcillations, or rather, they rollecj 

 like a velTel at fea. The fmall bodies, when de- 

 prived of their tails, were oval and tranfparent, 

 and refembled thofe pretended animals which are 

 feen in oyfter water on the 6th or yth day, or 

 thofe found in the jelly of roafted veal at the end 

 of the 4th day.

Between the loth and 12th hour, the liquor 

 was become very fluid, and all the globules ap-
