buildings at Cambridge will long remain a monument to the care, 
thought and energy he expended on their development. 
He was an ardent volunteer, and became a Captain in the old 
Y.M.S.C. in 1886, and gained his majority in 1902. On the 
outbreak of war he was mobilized with the R.A.M.C.(T.F.) in 
the Sanitary Section. In 1915 he was appointed M.O.i/C, the 
Irish Command Depot at Tipperary. In 1916 he was gazetted 
Lt.-Col. and Advisor in Pathology to the War Office, and in 1917 
Brevet-Col. A.M.S. and Inspector of Laboratories in Military 
Hospitals U.K. ; and there is no doubt that the continual 
travelling up and down the country necessitated by this last 
appointment, with its attendant strain and discomfort, was a 
material factor in his subsequent breakdown in health. He was 
thrice mentioned in despatches, and in 1919 received the K.B.E. 
for special services rendered. He resigned his commission in 1919 
on account of ill-health, but retained his rank. 
Woodhead was not a prolific writer, but such records of his 
activities as he has left behind demonstrate to the full that clarity 
of thought and critical judgment that combined to make him such 
a successful teacher. Whilst in Edinburgh he published two 
volumes, one in 1883, “Practical Pathology,” profusely illustrated 
by original drawings (representing actual microscopical prepara- 
tions), for many of which Woodhead himself was responsible ; this 
manual has passed through four editions, the last appearing in 
1910. In 1895, in association with Hare, he published “ Patho- 
logical Mycology.” In 1891 he contributed a volume to the 
Contemporary Science Series, under the title of “ Bacteria and their 
Products,” which remains to this day one of the best popular 
treatises on these minute organisms. He was Assistant Com- 
missioner to the Eoyal Commission on Tuberculosis, from 1892 to 
1895, and compiled a valuable Report to the Commissioners in 
1895 ; he was also a member of the 1902 Royal Commission on 
Tuberculosis. In 1893, together with Mr. Pentland, he founded 
the “Journal of Pathology and Bacteriology”; he continued its 
editor up to 1920, by which time it had become the official organ 
of the Pathological Society of Great Britain. In 1894 he 
published with Dr. Cartwright Wood “An Investigation into the 
Efficiency of Domestic Water Filters,” and there is no doubt that 
the opinions he formed at this time prompted the chemical experi- 
ments he carried out during the early days of the war, which 
resulted in the standardization of the chlorination process for 
purifying drinking water for the troops. He was also responsible, 
in association with the late Mr. Yasey, for the report of the Lancet 
Commission on the Standardization of Disinfectants (1912), a 
monumental work of the highest practical importance. 
Whilst Director of the Conjoint Laboratories he published a 
report on diphtheria for the Metropolitan Asylums Board, and
