years later he was appointed Professor of Botany in the Forestry 
Department at Cooper's Hill, and in 1895 was elected to the 
Professorship at Cambridge. 
The following are some of the distinctions conferred on him. 
He was elected a fellow of the Royal Society in 1888, and was 
chosen to read the Croonian Lecture in 1890, the subject^ being 
"Some relations between host and parasite in certain epidemic 
diseases of plants." In lvJ he Tim r.-ir; <>i r nbridg. made 
him a Doctor of Science, and in the following year the Royal 
Society awarded him the Royal Medal for his researches into the 
lirV-hi'sn.r tycetes. He was president of the 
botanical Wn>n of tin I itwi V- m n Toronto m 1S97, 
an- 1 president of the British Mycological Society from 1900 to 
1902. 
To return to the scientific work published by Prof. Marshall 
Ward we can only mention a few out of the large number of papers 
produced. Some of these deal with the life-history of fungal 
oarasites. e.if., a research en the strurtnre ami life-history of 
Kntijlom t Ii<<n ••■ i'(, !'!. [. Trans., 1887), an 1 " A Lily disease" 
(Ann. Bot. II., 1888). Others are concerned with bacteria and 
yeasts. Of these "The Ginger-beer plant and the organisms 
composing it" is a study of the biology of the dual organism, 
composed of a yeast and a baeteriimi 'symbioib-ally associated, 
having special interest in connection with the subject of fermenta- 
tion : ami a paper on symbiosis and symbiotic fermentation was 
published in the transactions of the Institute of Brewing (19(>1). 
A detailed work on the bacteriology of the Thames was carried 
out in conjunction with Prof. Percy Frankland, F.R.S., in the 
years 1893-6. In 1894 a paper published in the Philosophical 
Transactions of the Royal Society recorded a large number of 
experiments on the action of light on bacteria, and attracted a 
good deal of public attention, on account of the hygienic aspect 
of the subject. His later work was largely given to a study of rusts 
allied to that of the wheat, and very interestiim and important 
results were made known regarding physiological races (biologic 
tonus) of the rust which attacks various species of Bromus. 
was published in the Transactions of the Cambridge 
Philosophical Society (1902) and in other papers. 
Besides the original works referred to, Prof. Ward found 
nine to write several books, some dealing with the diseases of 
tth Forestry. The chief of these 
"»■<■: "• rnub, r and some of its diseases" (1889), "The Oak; a 
to Forest Botany" (1892), "Disease in 
• 8" (19(H), and "Trees "a large book, the 
publication of which is not yet complete. 
All Prof. Ward's work is characterised by extremely careful
