ANOTHERNEW MECHANICAL STAGE

for Spencer Master MicroscopeTHE Spencer Master Microscope No. 3-popular for criti- -NO3

cal research work because of its size and the convenienceof its low fine adjustment-may now be equipped with an-other large mechanical stage, No. "P."

Steadier, smoother action for the to and fro movement (50MM.) is due to a double application of moving power accom-plished by two pinions on a single shaft engaging two diagonalracks. The lateral movement (75 MM.) is achieved by meansof a quick acting sextuple screw and a carefully fitted nut.There are graduations and verniers reading to 1/10 MM. foreach movement. Slides as large as 50 MM. x 75 MM. maybe used.

THE MEAD JOHNSONVITAMIN A RESEARCH AWARD

THIS award was originally established by Mead Johnson& Company January 30, 1932. "Mead Johnson &

Company announces an award of $15,000 to be given tothe investigator or group of investigators producing themost conclusive research on the vitamin A requirements ofhuman beings." (See J.A.M.A., January 30, 1932, pages14-15.)

On February 11, 1933 (J.A.M.A., pages 12-13), "At thesuggestion of the Judges, a second (additional) Award of$5,000 is now offered. The basis for this enlargement isin the obvious possibility that within the time limit set(Dec. 31, 1934), no suitable evaluation of the vitamin Arequirements of human beings will have appeared. On theother hand, a laboratory investigation may have been pub-lished which will point the way toward clinical evaluation."

On that date, the Judges for the award wereannounced:Isaac A. Abt, Northwestern University; K. D. Blackfan,Harvard University; Alan Brown, University of Toronto;Horton R. Gasparis, Vanderbilt University; H. F. Helm-holz, Mayo Clinic; Alfred F. Hess, Columbia University;E. V. McCollum, Johns Hopkins University; L. B. Mendel,Yale University; L. T. Royster, University of Virginia;and Robert Strong, Tulane University.

Present StatusThe Judges met in Detroit, April 10, 1935, andtook the following action:

(1) To postpone until December 31, 1936, awarding ofthe main (Clinical) Award.

(2) To divide the second (Laboratory) Award, one-halfto Dr. S. B. Wolbach, Harvard University, for his basicwork on the pathology of avitaminosis A and his investi-gations on the regeneration of epithelial tissue impaired byvitamin A deficiency, and the relationship of vitamin A tothe integrity of the teeth; and one-half to Dr. Karl E.Mason, Vanderbilt University, for distinguishing exactlybetween the pathology of avitaminosis A and avitaminosisE, and for his contribution to the quantitative relation-ship of vitamin A deficiency to the keratinization of ger-minal epithelia. Some of this original work is still in press.

Checks for $2,500 each, in accordance with thedecision of the Judges, were promptly mailed byMead Johnson & Company to Dr. S. B. Wolbachand to Dr. Karl E. Mason.

MONOCHROMATIC FLAME BURNERA combination of a bunsen burner and an atomizer spe-

cially designed to give a continuous and intense monochro-matic light source over a period of several hours.

The atomizer when attached to a supply of compressed airblows a fine spray of solution in with the gas, giving a brightbroad flame with the color characteristic of the salt used.

The burner and the base are substantial iron castings,porcelain enameled throughout to prevent corrosion and con-tamination of the solution. The clamp, rods and nuts aremade of Monel Metal. The heavy glass vessel and atomizer,which are standardized and replaceable, can readily be re-moved for cleaning.

Purity of flame sources can be better maintained by usinga number of burners, keeping each one for its respective saltsolution.
