Y. wrtebricant must be squeezed out, leaving only an abrasive (itfilm of uniform thickness between the specimen and lap. 2?A)polishing machine providing sufficient pressure (about KMO.lb. per in.5) to secure the desired results is described and ipfflustrated. Pressure is applied through a ball joint to in- fisure a uniform distribution. Abrasives used are graded optical emery and calcined magnesium oxide (the ^regular reagent grade is unsatisfactory as a polishing ppowder). B.C.R. IgjftSurface finish- K. W. Connor and D. A. Wallace.

H.T. ^discriminate administration of vitamins to workers in dustry. ; American Medical Assn. Council on Foods In Nutrition and Council on Industrial Health. it~. Amer. Med. Assn.. 118, 618-21 (Feb. 21. 1942).-- . .^factory evidence of the wisdom of the general practice 7 providing all employees of industrial concerns with Mamins indiscriminately is lacking. When a satisfactory j.-udv of any given industrial situation indicates the wis- V of providing vitamins to employees, the Councils i-.-int out the necessity of observing the proper scientific I mitations of such action; after the employee has been re- i .-ired to a healthful state, the use of a good diet of natural lective foods thereafter should suffice. Nothing in this r.port is intended to belittle the significance of vitamins in :J:rition or the value of the proper use of added vitamins improving foods such as bread and flour. The need for avoidance of indiscriminate mass use of vitamins, a mctice which supports the commercial exploitation rather -m scientific rational use of these important dietary fac- is emphasized.

H.T. Lung function in silicosis.* E. Roelsen. Ptoc. Medical V*jr. Northern Countries. 19th Congr., Oslo, June, 1939; : ra Med. Scand., Supp., No. 123, pp. 236-43 (1941).--R. '.ports ihe principal results of lung-function tests on 40 or *" silicotic patients, including porcelain workers, stone masons, sandblasters, and foundry workers. He found a -crease in vital capacity and an increase of residual air, imperially' in the second and third stages of the disease. Tae explanation lies in the decreased motility of the thorax *dl and diaphragm, causing a diminution of lung elas- '-ity. The difference in alveolar ventilation of different actions of the lung is generally increased, considerably so TM the second and third stages. Lung functions are not as iccomplishN it process* at quandct available f* Nverely affected in silicotics as in emphysema patients. Ceram. Abs., 20 [31 78 (1941). F.S.M. . Methods of avoiding corrosion. Anon.

(3) glass for floats, springs, and mechaniparts, (4) molded porcelain where both dielectric rcngth and corrosion resistance are required, (5) plastics as Saran to replace brass and copper tubes, (6) ijitwilicon case on steel produced by heat-treatment as lhe Ihrigizing process. (7) thin lead coatings produced ;v dipping as by the Hurbenium process, (8) chemical surtreatments such as bonderizing, parkcrizing, black jetal. and others, and (9) silver plating or cladding - base metals for corrosion resistance. Many practical temples arc described, including glass tubing to replace "''kcl-chromium tubing for protecting sheaths for thermonipR-s; tjjjs Vycor glass is 96% SiO;, the remainder being ->vllv B;Oi. It has a softening point of 1510C. * 30, annealing point of SWC. m 20*. a strain point of *`C. * ^o, a density of 2.18, and a coctlicient of linear expansion of 7.8 to 8 X 10'1; the maximum temperature at -which it can be used for limited periods is 900* to 1000`C. M.H. New treatment for burnt (preliminary report). K. L. Pickrell. Bull. Johns Hopkins Hosp., 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 have with any other form of treatment used at the hospital. F.S.M. Pathogenesis of heat disease in man. B. Schlbgel and H. Boettnbr. Deut. Arch. klin. Med., 187, 193-205 (1941).--The effects ol heat are divided into three classes: exhaustion, stroke, and cramps. The authors conducted 50 experiments on 35 persons to study the behavior of the human body at the stage just prior to heat stroke and heat exhaustion. The subjects were kept in a chamber at a temperature of 40 *C-. (104F.), 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, including palpitation, oppression, dizzi ness. and fatigue. The body temperature in some cases rose to 38.5*C. (101.3F.), 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; in 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 in 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 circula 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. Pneumoconiosis--a study of 379 cases. 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 cases 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 in a direct ratio. W. stresses the need for more careful and detailed histories and physical exam inations. F.S.M. Preparation of slides for particle-size determination. L. Silverman and W. Franklin. Jour. Ind. Hyg. Sf 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 1 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. F.S.M. Significance of porphyrinuria in lead poisoning. R. Kark and A. P. Mbuclejohn. Jour. Gin. Investigation. 21, 91-99 (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 been 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. These results failed to demonstrate any / i: Vr .
