Of the Phenomena hi 



my great Surprize, it had no Man- 

 er of Effect upon thern ; the Mi- 

 crofcope exhibited them, after they 

 were taken out of the Air- Pump, 

 unaltered, and all of them acted 

 upon the Application of Water with 

 the fame undiminifhed Force, as 

 the reft of them had done before. 



To conclude, if I had ever feen 

 the fuppofed Animalcules in the 

 Semen of any living Creature, I 

 could perhaps be able to determine 

 with iome Certainty, whether they 

 were really living Creature?, or might 

 podibly be nothing more than im~ 

 menfeiy iefs Machines analogous to 

 thefe Milt-Vefiels, which may be 

 only in Large, what thofe are in 

 Miniature. For by Mr. Lewenhceck's 

 Calculation of the Number and Size 

 of the Animalcules in the Semen 

 of a CcJ-fi/Jj, one Million of them 

 would fcarce equal one of thefe Milt- 

 Vefiels, confequently where Twenty 

 five of thefe would appear at one 

 View in the Area of a Microfcope, 

 Nineteen Million, Six hundred, and 

 Twenty five thoufind would appear
