DIFFERENTSYSTEMS. 119 



In the year 1692, Valifnieri began his expe- 

 riments upon the teftlcles of the fow. The te- 

 fticles of the few differ from thofe of cows, of 

 mares, of fheep, of fhe-afles, of female- dogs, 

 of Ihie-goats, of women, and of molt viviparous 

 animals ; for they refemble a fmall bunch of 

 raifms, the grains of which are round and pro- 

 minent on the outfide ; between thefe grains are 

 fmallerones, which have not acquired full matu- 

 rity. Thefe grains appear not to be covered with 

 a common membrane. They are, fays he, a- 

 nalogous to the yellow bodies obferved in cows 

 by Malpighius ; they are round, and of a reddilli 

 colour ; their furface is interfperied with blood- 

 vefTels, like the eggs of viviparous animals ; and 

 the whole grains together form a mafs which is 

 larger than the ovarium. With a little addrefs, 

 thefe grains may be feparated from the ovari- 

 um, and each of them, after feparation, leaves a 

 nitch or depreffion. 



Thefe glandulous bodies are not of the fame 

 colour. In fome lows they are more red ; ia 

 others more clear ; and they arc of all fizes, 

 from the fmallcft feed, to that of a raifm. On 

 opening them, a triangular cavity appears, fill- 

 ed with a limpid liquor, which "toagulates with 

 hear, and becomes white, like that which is 

 contained in the veficles. Valifnieri expeded to 

 find the egg in fome of thefe cavities : But in 

 this he was difappointed ; though he made a 

 MreRil fcarch into all the glandulous bodies of a 



number
