Although a large number of the natives living in the bustees surrounding this tank constantly use and drink this water, no case of cholera has occurred amongst them. As you are aware from Dr. Koch’s official reports to his Government, this gentleman visited during his stay in Calcutta (February 13th and 20th, 1884) bustees in Sahib Bagan, amongst the inhabitants of which there occurred, i between January 21st and April 27th of this year, a severe outbreak of cholera. These bustees are located around a tank which for convenience sake may be here called No. 2. There are about two hundred families living around this tank, and, as is usually the case, the utilise this water for washing, bathing, cleaning, and drinking purposes. In this water Dr. Koch found the comma bacilli, and he quite arbitrarily concluded that they caused that outbreak of cholera. I visited this tank lately and found in its water undoubted comma bacilli. There has occurred, during the whole of November, 1884, one single case of cholera, although about two hundred families use the water. Close to this tank there is another tank, No. 3, and around this live also about two hundred families. As in the former case, the people here around tank No. 3 use the water for all purposes, including drinking purposes. The water of this tank is dirty, and a sample taken close to the shore revealed un- doubted comma bacilli. There has not occurred a single case of cholera in these bustees during the whole of this year. It is worth stating that there is a communication between tanks Nos. 3 and 2, there being a slight flow from the former into the latter. Tank No. 2 receives water from the ice- factory close by. THE REPORT OF MR. L. WRAY, JUN., ON COL- LECTING AND PRESERVING VACCINE LYMPH. THis report, which is addressed to the Assistant Resident at Perak, urges the need for more attention being devoted to the preservation of vaccine lymph. The report deals solely with the method of storage in tubes, and in it Mr. Wray points out that he has examined under the microscope tubes of lymph sent from England to the Government of Perak, and that he has "found some of them to be swarming with septic bacteria, and as a result void of micrococcus vaccinœ, and quite useless for purposes of vaccination." This is a reasonable ground on which to base his argument; but when he adds that such tubes "are constantly touched by hands that have, perhaps, only a few minutes previously been feeling the pulse of a fever-stricken patient or dressing sores of the most loathsome character," we should prefer to rely upon the rejection of lymph from persons guilty of such culpable carelessness, rather than upon the process of cleansing and sterilising the tubes. Mr. Wray describes the apparatus with which he effects his object to be a glass tube dilated in one part, and closed at its lower end by a piece of indiarubber tubing, pinched by a pinchcock ; the tube is filled with water, and the capillary lymph tube, after the latter has been filled with strong acid, has one end inserted into a pinhole in the indiarubber and the water is then forced through it. Subsequently, the capillary tube is dried in an oven and placed with others in a glass tube, hermetically sealed at one end and closed with , cotton-wool at the other. The whole are then exposed to a high temperature to sterilise them. Mr. Wray gives us no definite information as to compara- , tive results with lymph tubes sterilised and with those filled : without these precautions. A series of careful experiments with lymph taken at the same time would have a consider- able value in determining their worth; and at the same time it might be well to compare the results with those obtained by lymph stored in points or in other ways. It must not be forgotten that the destruction of the vaccine organism may come about from causes other than micro-organisms collected from without the body of the vaccinifer, and that the preservation of lymph may be dependent as much upon its growth as on its subsequent exposure to external influences. CYPRUS. THE report on the census of Cyprus in 1881, taken under the superintendence of Dr. F. W. Barry, late Sanitary Com- missioner of the Island, has just been published as a parlia- mentary paper. It shows the population to have amounted to 186,173 persons, being in the proportion of fifty per square mile. Of the total enumerated, 95,015 were males and 91,158 females, a preponderance of males which, " although contrary to the experience of all European countries, with the excep- tion of Greece and Bulgaria, has been found to exist to a greater or less extent in all Asiatic countries." The average number of inhabitants to each house was 4’24. Of the whole population 24’4 per cent. were Mahomedans, 73-9 per cent. members of the Orthodox Greek Church, and 1’7 per cent. belonged to other denominations. Under the head of "infirmities of the people" we find that the number of blind amounted to 12 per 1000 of the popula- tion, the average in England and Wales being only ’88 per 1000. This very high proportion is believed to be chiefly a result of the great prevalence of ophthalmia and, until recently, of small-pox, but is also in some measure due to the unwholesome surroundings and condition of the dwellings and to the want of personal cleanliness. The pro- portion of deaf mutes in the population is 1’2 per 1000, or double the ratio in England; and of persons of unsound mind (including lunatics, idiots, and imbeciles) 3’0 per 1000; but there is reason to believe this has been rather understated. It corresponds very closely with the ratio in England and Wales, which by the last census was shown to amount to 3’26 per 1000. There were 78 persons returned as affected with leprosy, of whom only ten were under twenty-five years of age. Dr. Barry remarks that there can be little doubt the number of lepers has been understated. "In Cyprus the leper, when recognised as such, is doomed by custom to social extinction. His property, if he has any, passes to his next of kin; he is an outcast from society, even from his nearest relatives; he can hold no official position, and even the offices of the church are denied to him. Under these circumstances it is a matter for surprise that so many as twenty-eight persons outside the leper farm have declared themselves to be affected with this loathsome disease." Of the lepers only two were returned as Mahomedans, th e rest being members of the Greek Church.

solely with the method of storage in tubes, and in it Mr. Wraypoints out that he has examined under the microscopetubes of lymph sent from England to the Government ofPerak, and that he has "found some of them to be swarmingwith septic bacteria, and as a result void of micrococcusvaccinœ, and quite useless for purposes of vaccination."This is a reasonable ground on which to base his argument;but when he adds that such tubes "are constantly touchedby hands that have, perhaps, only a few minutes previouslybeen feeling the pulse of a fever-stricken patient or dressingsores of the most loathsome character," we should prefer torely upon the rejection of lymph from persons guilty of

such culpable carelessness, rather than upon the process ofcleansing and sterilising the tubes.Mr. Wray describes the apparatus with which he effects his

object to be a glass tube dilated in one part, and closed atits lower end by a piece of indiarubber tubing, pinched by apinchcock ; the tube is filled with water, and the capillarylymph tube, after the latter has been filled with strongacid, has one end inserted into a pinhole in the indiarubberand the water is then forced through it. Subsequently, thecapillary tube is dried in an oven and placed with others ina glass tube, hermetically sealed at one end and closed with

, cotton-wool at the other. The whole are then exposed to ahigh temperature to sterilise them.

’ Mr. Wray gives us no definite information as to compara-, tive results with lymph tubes sterilised and with those filled: without these precautions. A series of careful experiments

with lymph taken at the same time would have a consider-able value in determining their worth; and at the same timeit might be well to compare the results with those obtainedby lymph stored in points or in other ways.
