 Mr. Leuivenhoeck, F. R. S. In a Letter to Mr. James Petiver. N° 331, 

 p. 3l6. 



The latter end of June 17n, I procured the testes of a young ram, and 

 having made a small incision in the lower part of each of them, where was a 

 protuberant roundness, and from whence the vasa semen deferentia proceeded, 

 I squeezed a little whitish matter out of them, which I immediately placed be-

 and moving : and because the animalcula could not be seen so distinctly, by 

 reason of the vast number and the quick motion of them in the little slimy 

 matter, in which they swam, I took a little rain water, about the quantity of 

 a great pin's head, and mixed it with an equal quantity of the said matter; 

 which being thus very much diluted, I placed it again before the microscope, 

 and then we could see very clearly the dead bodies of those animalcula, lying in 

 the liquor. 



About 10 or 12 days after, I got two other testes of a young ram, which 

 were something smaller than the former; and proceeding with them as before, 

 I found that the whitish matter was much more fluid than the former; and that 

 there floated in it a vast number of very clear small globular bodies, of which I
