Both these firms have engaged physiiians recommended by the industrial. Clinic, a n d are operating along the general lines recommended by the Clinio. During the year one large steel company established a Health Servios with a full time physician in charge. The Industrial Clinio was consulted in regard to the organisation of this, and actually conducted the service for six weeks during the absence of the physloian on account of sioknese. Another large plant manufacturing oompany established a Health Service, stimulated I believe by this Clinle, but the Clinic was not consulted as to its organisation. 2 (Bl X h e 'ids* af co-operative Health S a r d to small plants, whloh w a r sponsored by the Canadian Uanufaetarers Association, has made no-progress this year* (0) T hera have b een several calls for i n v e s t i g a t i o n of plant conditions, A fairly extensive study was made in one bronse foundry. 1 number of air analyses for lead were carried through* The results of these-'studies form the basis of a paper to be read at the annual m e e t i n g of the American Public H e a l t h A s s o c i a t i o n this fall.

However, It is hoped that as the value of this examination b e c o m e s a p p r e c i a t e d all d e p a r t m e n t s w i l l take advantage of it. The study of occupational diseases among the Out-patients of the H o s p i t a l continues. Some results of this work are now appearing. One concern, which formerly contributed a large n u m b e r of oases of lead p o isoning to this Clinic, has established a new factory, partly on account of the severe lead haiard which existed in the old plant, and another firm has installed a fume removal system which should reduce the hasard very considerably. 22 cases of aotlve lead poisoning were treated and investigated.

I b e l i e v e this Clinic is of real ralae to the c o m munity. I n d u s t r i a l workers can get goq d dental serTiee at a l o w coat, and since the Clin i c is o p e r a t e d at night, they need not lose time from their work. The financial status of the I n d u s t r i a l D e n t a l C l i n i c is satisfactory the fees from the patients being sufficient to pay the operating cost. FIELD ACTIVITIES.

Burnette, Esq., Metropolitan Life Insurance Co . , Ottawa, Cnt. October 11, 1932. Dear Mr. Burnette: You have asked me to let you hare a statement regarding in dustrial hygiene at McGill in time for the American Public Health Association meeting this month. As you know, I came to Montreal in August, 1927 to take charge of the Industrial hygiene work at McGill. The first aotivlty was the creation of the Industrial Clinic at the Montreal General Hospital. It was thought at the time that the best point of contact with Industry was through a clinic to which cases of occupational disease might be sent for investigation and treat ment. A considerable number of such cases were directed to the Clinie, particu larly cases of lead poisoning, and contaot was made with the industries from which they came. One plant with an exceptionally severe lead hazard actually erec ted a new building, partly, I believe, on our reeemendation, and several plants have Improved their working conditions, by installing various ventilating devices to carry away poisonous dusts and fumes. Several papers have been published on the subject of lead poisoning, copies of which are enclosed* The occupational poisoning work has been considered a less important activity than others, particularly on account of the fact that the num ber of cases of occupational poisoning is small compared with other diseases which affect industrial workers* All evldsnoe points to the fact that industrial work ers suffer in the main from the seas diseases which affect the general population, and that preventive medicine far industrial workers should be directed tomrds those diseases and not especially towards the so-called occupational diseases. For this reason, it was thought that a valuable service oould be rendered Industry in particular, and the e o m a n l t y in general, if Industrial health services oould be established in the larger industries, so that the health of the workers could be brought under the 1m e d i a t e supervision of a doctor and a morse, A good deal of time was devoted to waking contaot with in dustries which, it was thought, would be interested in a scheme of this nature. Considerable suooees was aohleved at first and five plants created health depart ments immediately under our supervision, while four or five othsr concerns were stimulated to establish medical departments. These medical departments have all given satisfaction and are still operating, but the Industrial depression during the last three years has made progress in this work very difficult. I** Industrial Dental Clinic o* -OO#3 pF.0' In connection with the work of the industrial health services, 0357 M if 2 an industrial dental clinic as established, tin activities of uhieh are recorded in an attaohed re-print. This elinio hae n nannd itaalf entirely and ia having a certain amount of difficulty now in making both ends meat. Industrial Mad leal Association of the Province of Quebeo la an outcome of the industrial hygiene work, the Industrial Uadi cal Asso ciation, P.Q,, was established in 1926* This is a bilingual Association which carries on independent activities, and is also considered a branch of the Province of <uebec Medical Association* Doctors, Fennoyer, Mercler, St. Jaques, and Tees, have been the successive presidents, and Dr. Ward and I have served as secretary. The organization took an active part at the request of the Workmen's Compensation Conxnission, in grafting the tariff of the 1928 Workmen's Compensation Law, and has held meetings approximately bi-monthly since its organization. Montreal Health Survey The Industrial Hygiene Department co-operated with the Montreal Health Survey Committee and prepared the industrial hygiene section of the report. Study of Asbeetosls In co-operation with the Metropolitan Life Insurance Company, a survey of two companies mining and milling asbestos, was made in July and September,* 1930. Physical examination of some 150 men was made, together with chest X-rays, and an interesting state of affairs was disclosed, which was reported to Dr. A.4. Innza of the Metropolitan Life Insurance Company, but to date permission has not been se- f cured to publish the results of the study. ^ --Lectures at McGill Courses of lectures on industrial hygiene have been given every year to ^ the third year medical students and graduate nurses, social workers and architects. General Publicity k number of public addresses have been given on the subjeot of industrial hygiene. Various papers have been prepared for publication or presentation at solantifio meetings, moat of which are enclosed. I h a w beer submitting review and editorials to the Cunadla! Medical Asso ciation Joumahfi.Mf W also acted as Joint editor with Dr. Cunningham of the Industrial Hygiene-Aeetloa of the Canadian Public Health Association Journal. k representation favouring the oreatian of Division of Industrial Hygiene in the Provincial Health Department, has been made to the Social Insuranea Comalssion and the Province of Quebec, and this Commission has reocaasnded suoh a Division to the Provincial Government. Present Activities The Industrial Cllnle has beta moved to the Univsrsity under the imnedlate dlreotlon or Dr. Vence Vard. The eupervleion ot the plaat w d i c a l depertmenta con tines, and ln addltlon, two new activities have besa started and ara now in operatlon: (1) a study of mercury polsonlng and (2) an industrial heaith survsy; 0358 (1) Our attention was drawn a year or ao ago to the mercury hazard In one of the plant* outelde the City, and aleo to the .faot. that a relatively email amount of experimental work had been done on lnduatrlal mercury poisoning. The co operation of the Department of Pharmacology at McGill a* obtained and an ex perimental atudy with dogs la now In progress to ascertain the minimum per- mlssable concentration of mercury In air. It is anticipated that a publication of this study will shortly be ready. This study Is being flnanoed entirely from the Industrial Hygiene f u n d s . m ***-^. jA} (2) In co-operation with the Canadian Tuberculosis association, the Provincial Health Department, and the Department of Industrial Hygiene at McGill, a study has been started with particular reference to tuberculosis In industrial workers, but also with reference to general health. Some 2,000 workers In three companies have already received a complete physical examination, with chest X-rays, and it is hoped to continue this survey so as to Include 5,000 employees in differ ent occupations. Thin survey has been under way for a year, a n d ^ s being fi nanced,partly by the*Provinclal Health Department, partly by the industries con cerned, and partly by^ourselves. The $25,000 promlsed by th Metropolitan Life Insurance has all basa paid, and soma $4,000 ls left to carry on th work. Ve are in hopes that th mercury study can be oempieted wlthln this appropriation, but lt vili not be possiti* to finish th industriai helth survey unleas additional funds are fartheoalng in activity which we h a beea endeavouring to establish for some years, ls a co-operative health service to plants too m u d i to provide a complete -- service of their own. in endeavour was made to get this servios under way, financed by the companies themselves, but various difficulties presented, chief of which was V the scepticism of the employers of its practicability.
