Collingridge volunteered for service as surgeon withthe Serbian forces. In spite of his youth he wasgiven responsible work in the organisation of

hospitals, and at the end of the campaign receivedthe Order of Takova from King infilan. After hisreturn to England he qualified as M.R.C.S. Eng. in1877 from St. Bartholomew’s Hospital, and graduatedboth in law and medicine at Cambridge, later beingcalled to the Bar as a member of Gray’s Inn. Two

years of private practice followed, after which, in1880, he was appointed medical officer of health forthe Port of London. During the 20 years he heldthis office there was great advance in the practice ofport sanitation, and Collingridge’s part in the develop-ment of London’s protective health service was alarge one. His work was both responsible and difficult, and was the more conspicuous becauseduring two continental epidemics of cholera he hadto devise measures for guarding against the spread ofthe disease to this country. Problems of this kindinterested him greatly, and he chose Quarantine asthe subject of his lIilrry- Lectures,1 delivered in 1897before the Royal College of Physicians, in which liemade an effective attack both upon the theoreticalbasis and practical application of the measure.It was not one, he said, that could usefully be enforcedby a commercial country ; it was expensive, it ledto a false sense of security, and it involved seriousdanger to health from the detention of vessels inconditions that were often insanitary and keptpeople within ranre of infection. Sanitation and arational system of medical inspection must provemore efficacious and less burdensome. Dr. Collingridgealso showed himself a warm advocate of better con-ditions of life for the mercantile marine, and a gooddeal of the work which is gradually leading to theirimprovement has been done by men who becamefamiliar with the work which won praise for hisdepartment. In 1901 lie was transferred to the postof medical officer of health for the Citv of London insuccession to Dr. Sedgwick Saunders, and here also,before his retirement in 1913, he was successful inhis work for the public health. Not all his schemeswere carried through without opposition, and at timeshe had to face a great deal of criticism, especially inregard to his crusade against the unclean conditionsin which the oyster was bred and distributed for theLondon market. He did the same service for thecockle—the poor man’s oyster, as he called it.Outside his official duties. Dr. Collingridge was akeen soldier. At Cambridge he joined the UniversityRifle Corps, and on coming to London he was forten years a member of the Honourable ArtilleryCompany. His later service included seven yearswith the Volunteer Medical Staff Corps, and eightyears as officer commanding the Militia Medical StaffCorps. Throughout the late war he was in charge ofAuxiliary Military Hospital 112. in Kent. He livedfor a long time in this county, but later moved toBerkshire, where he became a justice of the peace.The end of his life was spent at Pennington, inHampshire.Dr. Collingridge was a Knight of Grace of theOrder of St. John of Jerusalem. He married a

daughter of Captain Thomsett, C.M.G., R.N.

post-graduate week of the College of Nursing, held atManchester from April 2.5th to 30th, Dr. W. G. Thomson, deputy superintendent of the Cheadle Royal Asylum, raisedthe question how far the liberties of mental defectivesought to be restricted. Realising that in the majority of casesno cure but only an amelioration of the condition was possible,it remained to consider how this might be effected. Muchdepended on the social and economic position of the parents.The vast majority of defectives could not be cared forwithin the family circle. At present the difficulty was thataccommodation was insufficient for all the cases requiringtreatment. Even if this was surmounted there was alwaysthe argument that force must not be used, that the lawmust not be invoked to separate the kind parents from amember of the family who was the object, possibly, ofmore affection than the normal children. It did not appearwise to be too sentimental, and such cases were more oftenhappy in institutions than they were at home. At institu-tions they received specialised attention, and were kindlyand humanely treated. The real question at issue waswhether the good of the child was to be subordinated to theliberty of the parents. As to the problem of propagationhe thought segregation was the remedy that appealed tomost people.
