This plan was frustrated by the Ijreakiiig down of liis 

 health. He became principal of the North Ward Grammar 

 School in Camden, in 1868, succeeding in that position 

 William L. Sayre, noAv principal of the Central Manual 

 Training School. When Mr. Sayre left the Stevens School 

 in Camden, Mr. Kain took his place there. In 1874 ^Ir. 

 Kain began his work in Philadelphia as Principal of the 

 Northwest Boys' Grammar School at Fifteenth and Race 

 Streets, and continued his work there until the close of 

 1886, when he accepted the position of Assistant Superinten- 

 dent of Schools, to which he was appointed by Dr. MacAllister 

 in November of that year. 



Mr. Kain is an expert photographer and uses the 

 stereopticon skillfully. The development of the present 

 illustrative movement in the schools is largely due to his 

 efforts. He has been instrumental in extending the work in 

 several states. He has devoted a great deal of time to 

 scientific work, particularly to microscopy, and has worked 

 up the diatoms of New Jersey for the state geological 

 survey. 



Mr. Kain received the dearree of A. M. from Lewisburo-, 

 now Bucknell University, in 1868. He is President of the 

 Teachers' Photographic Association and is a member of the 

 Educational Club, the Teachers' Institute, the New York 

 Academy of Sciences, the Torrey Botanical Club, a corre- 

 sponding member of the New York Microscopical Society 

 and an honorary member of the State Microscopical Society 

 of Illinois. 



His principal papers on the diatoms appeared in the 

 Bulletin Torrey Botanical Club.
