Vhibricant must be squeezed out, leaving only an abrasive p/film of uniform thickness between the specimen and lap. -A polishing machine providing sufficient pressure (about 10lb. per in.1) to secure tbe desired results is described and -.illustrated. Pressure is applied through a ball joint to in- .' sure a uniform distribution. Abrasives used are graded _J".'-3C3`/> optical emery and calcined magnesium oxide (the /regular reagent .grade is unsatisfactory as a polishing .-powder). B.C.R. .-'v Surface finish. R. W.

MJL New treatment for bursa (preliminary report). 7L b. PtCCJtELL. Butt. Johns Hopkins Hasp.. 69, 217-24 (Aug., 1941).--The method of treatment involves the application of 3% sulfadiazine in 8% triethanolamine by spraying. Full details of the immediate and later treatment are given. In the opinion of the surgical staff, the burned areas of the 115 patients healed more rapidly than they would hare with any other form of treatment used at the hospital F.S.M. Pathogenesis of heat disease in man. B. Schlxcel and H. BosTTNXJt. DeuL Arch, hiin. JJed^ 187, 193*205 (1941).--The effects of heat are divided into three daises: exhaustion, stroke, and cramps. The authors 50 experiments on 35 persons to study the behavior of the human body at the stage just prior to beat stroke and beat exhaustion. The subjects were kept in a chamber at a temperature of 40*C.. (104*F.). for 2 hr. when possible. Losses through the skin amounted to 11 gm. sodium chlo ride. 430 mgm. nitrogen, and up to 2700 gm. water. Most of the persons complained of symptoms referable to the nervous system, mdudisg palpitation, oppression, dizzi ness. and fatigue. The body temperature m some rose to 38.5*C. (10l.3*F.), but the rise was not related to heat tolerance. The pulse rate, however, rose sharply to 176 at the point where the heat could not be tolerated; m resistant persons 140 was the upper limit. In a few per sons on whom the experiment could be conducted to a stage of imminent collapse, a strong decline of the systolic and diastolic pressure was seen. All the observed phe nomena indicated that the blood goes to the diluted pe ripheral vessels, while those m the internal organs, including the brain, are contracted. The characteristic of heat ex haustion is a breakdown of the circulatory regulation with an intact temperature-regulation system. The syndrome of heat stroke consists of failure of the temperature-regu lating system combined with long resistance of the tircula- tory regulation. Exhaustion of sodium chloride reserves is the important feature in heat cramps. The authors be lieve that the organ primarily damaged by heat is the adrenal cortex. F.S.M. yPneumoeomotia--a study of 379 eases. H. B. Wil liams. Med. Bull. Veterans' Admin., 18, 250-53 (Jan., 1942).--A survey was made to determine the relative inci dence of pneumoconiosis in beneficiaries of the Veterans' Administration. A review of 379 eases of individuals who had been exposed to numerous occupational dust hazards is presented. Of this number, 179 cases were classified as pneumoconiosis, either uncomplicated or complicated by infectious disease, A detailed system of classification is included. No definite conclusions are drawn, but the data support the belief that pneumoconiosis increases suscepti bility to tuberculosis m a direct ratio. W. stresses the need for more careful and detailed histories and physical exam inations. F.S-M. Preparation of tildes for particle-size determination. L. Silverman and W. Fkakcjh. Jour. Ind. Hyj. 8* Toxicol., 24, 51 (March. 1942).--It is suggested that, in following Green's technique of preparing slides for particle- size determination, it is possible to crush particles of the range L to 10 microns. This seemed to be borne out by a comparison of the results of counts made on slides prepared by evaporation of suspensions and by mechanical disper sion. FB^L Significance of porphyrinuria in lead poisoning. -R. Kajuc and A. P. Mxxklejokn. Jour. din. Iraestiiation, 21, 91-09 (Jan., 1942).--Solutions of hemoglobin were injected into two subjects with lead poisoning, anemia, and porphyrinuria. The injection was followed by a rise in plasma bilirubin resembling closely both in degree and . time of onset the bilirubinemia which has bees observed in normal subjects under comparable conditions. It was also accompanied by transient increase in urinary uro bilinogen excretion. The injection resulted in no detect able increase in the excretion of coproporphyrin either in the urine or feces.
