Harry Marshall Ward, eldest son of Francis Marshall 

 Ward, was born in Hereford, March 21, 1854, but he came of 

 a Lincolnshire stock, settled for some time in Nottingham. 

 From unavoidable causes he left school at 14, but afterwards 

 continued his education by attending evening classes organised 

 under the Science and Art Department. To that Department, 

 he owed indirectly the opportunity of a useful and brilliant 

 career. His means were small, and his earliest aim was to 

 qualify as a science teacher. He was admitted to a course of 

 instruction for teachers in training given by Prof. Huxley in 

 1874-5. Although he must have derived from it a sound insight 

 into the principles of zoology, the subject does not seem to have 

 had any permanent attraction for him. 



In the summer of 1857 Ward came under my hands in a 

 course of instruction in botany which I conducted with Prof. 

 Vines in the Science Schools at South Kensington, and from 

 this time onwards we were in intimate relations to the close of 

 his life. I can best tell the story as it came under my eyes.
