{Read before the American Philosophical Society, December 7, 1S9^.) 



The preeminence which American pharmacy has for many years main- 

 tained may without doubt be largely attributed to the scientific zeal and 

 ability of the teachers of pharmaceutical science in the various institutions 

 of the country. To no one belongs a greater meed of praise than to the 

 late Prof. Maisch, a member of the American Philosophical Society, to 

 which he was elected January 18, 1884, 



John Michael Maisch was born of humble parents in Hanau on the

Under Dr. Bromies he soon demonstrated his fitness for original inves- 

 tigation in chemistry, and was permitted by him to assist in certain 

 studies of the fatty acids and resins. 



For a time his inclinations were towards theology, but his increasing 

 interest in natural science led him to abandon the idea and to devote him- 

 self with such ardor to his scientific studies as to undermine his strength 

 to such an extent that it became necessary not only to give up close appli- 

 cation for a time, but, in the end, to relinquish his strong desire for a 

 university course. 



Entering the military service of Hesse, he became impregnated with the
