ANNIVERSARY ADDRESS. 37 
the first floor will be entirely occupied with the laboratories of the 
Government Analyst; the second floor will be occupied with a 
commodious and well equipped bacteriological laboratory ; while 
in the basement, which, owing to conformation of the site is at the 
ground-level at the rear of the building, will be conducted business 
connected with hospital accommodation for the sick poor, public 
vaccination, and some other matters administered by the Chief 
Medical Officer. At the same time the staff is gradually being 
improved and added to in important respects ; and in the course 
of a year or two there is every reason to hope that the colony will 
at length be found furnished with a Public Health Department 
capable of safeguarding the prosperity of the people in important 
respects, and competent to perform its proper functions. 
During the year the usual routine examinations of specimens 
from diseased animals were continued in the Biological Laboratory 
of the Board of Health, by Dr. Frank Tidswell, bacteriologist to the 
department, being mostly diagnostic examinations for anthrax, 
tuberculosis, ete. Some preliminary observations were made on 
the disease of pigs known to butchers as “pig quinsy,” which 
tend to show that the malady in question is a form of septicemia. 
This diagnosis is provisional only, pending the elucidation of details. 
Observations made on a form of ulceration of the cornea of the 
eye in cattle suggest that in most instances the affliction is of 
traumatic origin. The examinations of bovine tumours were 
Continued, the growths specially examined being from the orbit of 
bullocks. The results show that the tumours are sometimes true 
Cancer of the form known as epithelioma. Occasional bacterio- 
logical examinations of the water supplied to Sydney furnished 
further evidence of its microbic purity. Samples of water from 
Wells yielded abundant crops of bacteria, not always of a harmless 
The most important work undertaken in the laboratory 
Was the histo-pathological examination of the organs of lepers 
deceased during the year. Detailed descriptions were published 
In the report of the Health Department on Leprosy in New 
South Wales, for the year 1895. The report is illustrated by co:
