and the coroner refused to allow the solicitor to pursue thisline further without notice. The solicitor called another
practitioner (Dr. W. H. Cooke), who said that he consideredthat a person dying from sudden cardiac failure wouldnot get up after having fallen down. In the end the juryreturned a verdict of death from disease of the heart, butwhether accelerated by shock of any kind there was noevidence to show. We think everyone will agree that thecoroner deserves the thanks of the profession for the way inwhich he conducted this inquiry. Here were two medicalmen giving evidence on the same questions and taking anapparently opposite view, but, as the coroner said in summingup the case, Dr. Cooke had not attended the post-mortemexamination, but simply gave his evidence on generalities.As to the verdict, he said, they might return one absolutelyin accordance with the evidence of Dr. Heathcote. This the
jury proceeded to do and we think everyone will agree with it.
SMALL-POX IN CYPRUS.
According to a communication from Reuter’s agent atLarnaca, published in the Tinzes of the 2nd inst., anepidemic of small-pox broke out towards the end of last
month in Cyprus and was especially severe in the Turkishquarter of Larnaca, other parts of the town having beenlikewise attacked. The appearance of the disease in
Larnaca was soon followed by an exodus of people fromthat place to other towns and villages in the island, andit is feared that the disease disseminated in this waymay soon become widespread unless prompt and stringentprecautions are taken. The disease is stated to have beenintroduced by a Turkish family from B6iifit. Veryinadequate means for the isolation of the sick, and thoseof the most primitive kind, exist in Cyprus as may well beimagined; there is a paucity also of medical attendance ;and we know next to nothing of the condition of the popula-tion of Cyprus as regards vaccination. It seems probablethat the island will furnish another object lesson of what theravages of small-pox may effect among an unprotectedpopulation. There are some advantages in living underBritish rule under such circumstances as these, for we dopossess laws for the repression of contagious disease and themachinery for practically applying them.
VARICELLA GANGRÆNOSA.
OUR knowledge of varicella gangraenosa is still so incom-plete that every well-recorded case is of interest. In the
September number of the Archives of Pediatrics are given twogood examples of the disease. The first is described by Dr.William F. Lockwood, of Baltimore, and is accompanied by aphotograph. A well-nourished female child, aged two years,exhibited the eruption of varicella. Next day a wide zone ofdusky red dermatitis occupied nearly the whole surface ofthe trunk. Rapid ulceration of the spots within this areaensued. The contents of many of the vesicles became
hasmorrhagic. Bleeding from the mouth and nose occurredand blood was extravasated in the skin over the pubes andabout the genitals. The gangrenous spots varied in depth,and in size from a pea to a surface measuring 1 in. by2 in..They often occurred where there were no varicellavesicles. On the trunk were large patches where theepidermis only was removed, exposing purplish dry surfaces.These were due to the dermatitis, and did not radiatefrom the chicken-pox vesicles. The deeper spots showed adry, hard, black eschar in the centre, an ulcerating border,and an elevated inflamed edge. The left eye was closedfrom swelling and ulceration of the upper lid, and there wasfree purulent discharge from between the lids. The childemitted an extremely fetid odour. Death took place on theeighth day, apparently from broncho-pneumonia ; but satis-factory examination of the chest was not possible. The
second case, described by Dr. Lewis Mann Silver, of NewYork, was that of a boy in good condition, aged two years.The illness began with diarrhoea, which was followed by atemperature of 103° F., lethargy, and a convulsion. On thefourth day the body was covered with the characteristic rashof varicella. The mucous membranes of the mouth and
conjunctiva were congested. On the third day of the
eruption circles of congestion from 4 in. to t in. in widthwere noticed around several of the spots, which hadbecome black and depressed in the centre. Next daythree gangrenous areas, measuring from 1 in. to 22 in.across, appeared on the neck. On the following dayboth eyelids were so much swollen that they could notbe opened, and there was a profuse discharge of blood andserum from the mouth and nose. The urine containedabundant albumin and numerous granular casts. The childdied in the evening soon after a convulsion. It is curiousthat varicella, the mildest of all the infectious diseases,should present such a grave complication. What explanationcan be offered ? Mr. Hutchinson, who first described the
disease, attributed the occurrence of the gangrene to idio-
syncrasy, as it usually occurred in healthy children.Dr. Barlow, however, denies this and asserts that in
none of his cases were the children healthy. A second
infection by some microbe supervening on the varicella hasalso been offered as an explanation, but evidence on this
point is wanting. ___
EXACT LOCALISATION AND MEASUREMENT BYTHE X RAYS.
As most workers with the Roentgen rays know it is oftenvery difficult to ascertain by the photographs they producethe exact locality of foreign bodies embedded in the tissues.The x ray photograph fails to give any definite informationas to the exact position and size of the foreign body, andthe surgeon when exploring for it has met with dis-
appointment and dissatisfaction because he may have causedhis patient pain without discovering the locale of the
foreign body. This has detracted very considerably fromthe value of x rays in surgical work. A method,therefore, which ensures the exact localising of the
foreign body in both a vertical and a horizontal plane andthe exact determination of its size will be of immenseservice. We hope shortly to bring to the notice of our
readers an account of this method which hag been carefullyelaborated by Dr. W. S. Hedley and Mr. MackenzieDavidson. For the present all we need say is that the
method of measurement employed renders the x rays a reallyaccurate means of locating the position and size of foreignbodies in the tissues. At a demonstration at which we were
present the results were satisfactory and convincing bothas to the practicability and utility of the method, whileit relieves the patient of any unnecessary inconvenience anddetention.
SURGICAL SYMPTOMS IN CONNEXION WITHFILARIA SANGUINIS.
AT a recent meeting of the Bombay Medical and PhysicalSociety Surgeon-Lieutenant-Colonel W. K. Hatch calledattention to the enlargement of various lymphatic glandsand the varicose state of the lymphatics of the spermaticcord which are met with in cases of filaria sanguinis. A full
description of the former of these conditions has hardly, hesaid, been given by any writers with the exception of Dr.Patrick Manson and the late Dr. Vandyke Carter. The glandusually affected are those in the groin, and next in order offrequency the axillary, then the iliac glands, and very rarelythose of the neck. The glands have usually a soft, doughyfeel and when small can be made almost to disappear, butwhen the pressure is removed they gradually resume their
