DIFFUSION OF CHOLERA. 195 



medical board at Madras contains an interesting map, show- 

 ing its track through the Deccan and the south by an ir- 

 regular course, sometimes along the high roads, sometimes 

 in cross directions ; but, in the end, leaving scarcely any 

 point of importance untouched. It reached Nagpore on 

 the 15th May, — Bombay, by way of Poonah, on the 14th 

 August, — Hydrabad on 25th July, — Madras on 8th October, 

 — and finally the extreme stations of Trivander and Palam- 

 cotta in January, 1819. Throughout these provinces it 

 manifested itself in various degrees of intensity. In gen- 

 eral, however, this dreadful disease seems to be marked 

 rather by the fatality of its action on those attacked than 

 by the great number who come under its influence. The 

 entire amount of cases occurring in the army of Fort St. 

 George during 1818, the most severe year, was 1087 out of 

 10,652 Europeans, and 3314 out of 58,764 natives. Of the 

 former 232, and of the latter 664 died. — (Report of Madras 

 Medical Board, p. 28.) In the island of Bombay, which 

 contains a population of about 2 1 0,000, the ascertained cases 

 were 15,945, of which 14,651 were medically treated, and 

 the deaths among these were only 938, or 6 4-10 per cent., 

 perhaps the smallest proportion of mortality that has any- 

 where been observed. — (Bombay Report, App., p. 13, 14.) 

 Instances, however, are given of single corps, particularly 

 on a march, suffering much more severely. The 2d bat- 

 talion 20th regiment of native infantry was marching to 

 Hydrabad, when of about 1150 men 200 were attacked, and 

 73 died. The 1st battalion 1st regiment, on its road from 

 Nagpore to Hydrabad, out of 1010 men had 167 attacked, 

 of whom 64 died. His majesty's 54th regiment, after land- 

 ing at Madras, when proceeding to Bangalore, had 159 out 

 of 632 attacked, and 54 died.* 



Another unexpected crisis arrested Sir Thomas Hislop 

 with thn army of the Deccan, just as he had arrived on the 

 frontier of Malwa. Intelligence then reached him that 

 Bajee Rao had taken up arms and attacked the British res- 

 idency in his capital. Sir Thomas then judged it neces- 

 sary to fall back, that he might support the reserve corps,

 with the train of historical events, is, in relation to its symptoms and 

 cure, treated of In the succeeding volume, under the head of " Spasmodio 

 Cholera," p. 368.
