?54 HYDERABAD. The sub-joined tables give the disease statistics of the troops stationed at Hyderabad between 1877 and 1881. The ratio of the admissions and deaths from the principal diseases per 1,000 of the aggregate annual strength was during the 5 years as follows :- Period-Five years, 1877-81. Cholera. Enteric Fever. All Fevers except Enteric. Dysentery. Diarrhœa. All Causes. A. D. A. D. A. D. A. D. A. D. A. D. Artillery 4.9 3.3 899.8 19.7 37.8 1,811.2 11.5 Infantry 947.4 0.8 27.9 27.8 1,623.4 8.5 There was no cholera among the troops during the above years and no case of enteric fever occurred among the Infantry. This fact is very noteworthy as there was in 1880 and 1881 a detachment of the 98th Regiment recently arrived from Malta in the station. The very dry climate of Hyderabad may possibly be a factor in this exemption. In 1879, two cases of enteric fever took place in the C/2 R. A., one of which is said to have been contracted on the line of march, but no cause could be assigned for the other. The case that occurred in N/1 R. A. in 1881 was contracted in Karáchi, and is, therefore, not due to disease causes in Hyderabad. The Infantry detachment was on the whole healthier than the men of the battery ; but it will be observed that the cases of remittent fever were more numerous in the Infantry than in the Artillery.
