 th^n this and say that microscopy is more cosmopolitan in 

 character than any other science. If I did not believe this to be 

 true, I should not have consented to occupy the honorable position 

 which I now hold by your sufPrages, for there are many members of 

 this society to whom the honor more justly belongs by virtue of 

 greater familiarity with the technics of our science. I suppose I am 

 indebted to this expression of your confidence on account of the use 

 which I have made of the microscope as an essential factor in a 

 single line of research. 



It is the glory of our science that the microscope supplements 

 nature's vision to such an extent that we can submit nearly every 

 theory, nearly every deduction from experiment, nearly every fact of 

 observation, to the supreme and only test by which a real truth in 

 nature can be established, viz. : through the medium of the senses 

 which we have been endowed by the Creator. It has been said that 

 microscopy has no claim to be regarded as a science and that the 

 microscope is simply an instrumental agent occupying with respect 

 to other sciences a position similar to that which the telescope 

 sustains in its relation to astronomy. A convincing answer to this 

 criticism is found in the fact that the telescope is limited in its
