in a square close to the sea, and near it was another building 
inhabited by a set of Gaolis or milkmen, and a cowshed. When 
plague broke out among the Mangs, the Gaolis noticed that 
rats were dying in their quarters, and therefore wisely removed to 
the cowshed close by. They had no cases among them, though, 
with the exception of one family, they were not inoculated. Thus 
the isolated Mang community, numbering sixty-one persons, afforded 
a good opportunity for an exhaustive enquiry ; and this was accord- 
ingly carried out by Dr E. L. Hunt, one of the medical men sent 
out to Bombay by the Secretary of State for India for temporary 
plague duty, and acting at the time as Inspector of Inoculation, 
assisted by Dr Arjani, Section Medical Officer of A. Ward, acting 
under the direction of Mr Haffkine himself. 
Of the sixty-one inhabitants, fifty-seven were either seen personally 
by one or other of the above-named investigators, or, if they had 
died meanwhile, the papers relating to them were secured from the 
adjacent plague hospital where they had been treated. The remaining 
four were not seen personally, as they had left the locality, three 
having gone to Poona, and one, a professional beggar, having dis- 
appeared in the city of Bombay. Only one of these four had been 
inoculated, and none of them were attacked. With the exception 
of these four, about whom the statements of neighbours had to be 
accepted, it was possible to furnish documentary evidence for all, 
showing when and by whom the inoculations had been performed, 
the date, duration and termination of the illness, with all the 
hospital notes and charts, and the condition of the survivors in 
July 1900, five months after the epidemic ceased. All this evidence 
was submitted to Government and published by them in full. The 
account now r given is a condensation of this report. 
The first case of plague developed symptoms on the 1st of 
February 1900, on the 2nd of the same month seven were attacked, 
on the 3rd, six, and then one case occurred on each of the following 
dates, viz., 4th, 5th, 7th, 9th, 10th, and 12th February. Altogether 
twenty attacks took place, with twelve deaths. The inoculations 
had been performed on various dates from 11th December 1899 
to 29th January 1900. The single case among the inoculated was 
in the person of a female, inoculated on 18th December, and attacked 
on 9th February : she recovered.
