facts, but found nothing to contradict the statement last 

 cited. At that time, also, physicians were asserting, 

 over their own names in the daily press, that there was 

 no one-seventy-fifth in existence, but, confronted with it, 

 they then said it was good for nothing. The satisfac- 

 tion expressed by thousands who have seen the public 

 demonstrations, ought to suffice. 



26. This is a letter dated editorial rooms " Our Day," 

 17 Beacon Street, Boston, January 30, 1895 : " Dear Dr. 

 Cutter : That powerful microscope of which you asked 

 me to give an opinion needs no commendation except its 

 own worth. It was greatly admired in the exhibitions 

 you gave in Boston to my audiences of from 2000 to 

 3000 people, and containing hundreds of teachers, preach- 

 ers and other educated men. The instrument has a his- 

 tory in Boston and New York that establishes its fame. 

 Yours truly, Joseph Cook." 



27. In relation " to the use of the one-seventy-fifth in 

 microchemical examinations of blood-stains," Dr. Harri- 

 man writes, January 25, 1895 : " * * * * * When 

 compared with lower power objectives, the one-seveuty- 

 fifth made by Tolles presents a very striking exhibition 

 of blood corpuscles, clear, round and well defined, and 

 there is no mistaking the difference under such high 

 magnifying power. The morphological changes are 

 more ably demonstrated by its use. * * * * " 



28. Recently, it has brought out the so-called ''Plasmo- 

 dium malarise " in red blood corpuscles with surprising 

 beauty, clearness and color. I say " so-called," because 

 the patient did not have malaria, and I say this because 

 the appearances varied from the typical plasmodium to 

 twin symmetrical spores, and because the color of these 

 spores was distinctly copper-colored. For years I hav^e 

 taught that this was characteristic of the spores of 

 Crypta syphilitica.
