61 EXTENSION OF CHOLERA TO CEYLON. Invasion of Ceylon in June. Influence of immi- gration from Southern India. 79. Although the sanitary supervision of the Island of Ceylon does not fall under my jurisdiction, this would seem to be the proper place for noting that the epidemic, after invading the Tinnevelly District, passed over to the north shores of the island, which were reached early in June. A local outbreak had occurred, however, in a village near Point de Galle so early as the 16th May. It would seem probable that the Galle cholera, and that on the northern road, must have reached the island by different routes. The particulars in regard to the development of cholera in Ceylon point, I think, most clearly to the influence of human intercourse between the Southern districts of India and Ceylon, the localities affected being chiefly those on which coolies travel to and fro. The report of the Principal Medical Officer, Civil Department, Ceylon, is given below. From the Principal Civil Medical Officer and Inspector-General of Hospitals in Ceylon, to the Honourable the Colonial Secretary, Colombo, dated Colombo, 28th September 1870, No. 339. I have had the honour to receive your letter, No. 253, of the 28th July, transmitting to me copy of Proceedings of the Madras Government, dated the 9th July, No. 850, on the subject of cholera in Southern India, and requesting me to report on the origin and progress of the present outbreak in Ceylon. 2. In explanation of the delay in forwarding this report, I have the honour to state that I awaited the receipt of the report, called for from the Colonial Surgeon of Jaffna, on the result of his visit of inspection down the central road from Jaffna to within a few miles of Dambul and on his return, striking off at Mattakachchee along the road to Mannar, which is frequented by the cooly immigrants proceeding from the coast to the interior of the island. 3. This report, with its explanatory maps, is now attached, and it affords a fall detail of the origin and progress of cholera along the central road traversed by coolies on their way to the inte- rior of the island, and on their return to the coast. 4. It also finally settles the question as to the origin of the disease, which has been recently raised by the Government Agent for the Northern Province. 5. The letter of the Sanitary Commissioner to the Indian Government, dated 1st July, No. 695, clearly states "that cholera had been prevailing in the Southern Districts of India for some months past. "The disease became general in Tanjore so long back as October and November 1869. It then extended to Trichinopoly and Madura Districts, and, lastly, to Tinnevelly." 6. It had, moreover, prevailed in Tuticorin, in a minor degree, from 25th April. 7. With these statements, and the facts brought forward by Dr. Ondaatfe, no reasonable doubt can remain that the cholera which appeared in the north of the island and extended itself along the central road even as far as Matale and Kandy-spreading, in a few instances, laterally to Anuradhapura and some neighbouring native villages, as reported by the headmen, locating itself- in some of the bazaars, where the in-coming coolies were in the habit of resting, and thence regur- gitating backwards to Davipatam by means of gangs returning to the coast contracting the disease at the halting places resorted to by the infecting gangs recently arriving-had its origin in the Southern Districts of India, and not in Ceylon. 8. The first cases reported at Matale were coolies picked up on the road while proceeding towards the interior of the island on the 19th and 20th June, and the two first cases which occurred in Kandy were two Canarese, also on their way to the coffee districts, who were found in a state of collapse in the cooly shed at Mahayawa, at a distance of a mile from the town on the 12th June, both dates being from nine to sixteen days subsequent to the first cases reported along the central road. 9. The disease extended in Matale and in Kandy to the inhabitants; but, although very fatal in its results, it limited itself to a comparatively few cases in both towns, and can no where be said to have assumed the form of an epidemic.
