By E. V. COWDRYProfessor of Anatomy, The School of Medicine;

Washington University, St. Louis, Mo.

Thoroughly revised. Large octavo, 426 pages,illustrated with 317 engravings, 13 in colors.

Cloth, $7.00.

In the preparation of the third edition of thiswork, the author has simplified his text by theomission of certain details so as to give increased

emphasis to what he believes to be the fundamen-

tals. The object has not been simply to expeditethe teaching of histology, but rather to permit a

closer focussing of attention on the correlation ofform and function by stressing the dynamics of thebody in action.

From wintudr

Lethal exsanguination of two condemned criminals was the method employed by vonHaller to determine human blood volume in the 18th century. Interest in the diagnosisand treatment of shock since then has led to a relatively simple technique, involvingintravenous injection of a measured amount of blue dye, following which a small speci-men of the blood plasma is compared spectroscopically with a standard to determinethe dilution of the dye. However, application of this method proved hazardous becausethe dye frequently caused serious reactions when injected. War required speedy solutionofthis problem, and the task was given to the Warner Institute for Therapeutic Research.

Warner scientists developed and carried out a new synthesis which yielded thedye in a state of exceptional purity. Methods of standardization, ampuling and steriliz-ation were developed to make it safe for injection. A compact kit was also devised fordetermination of plasma volume (or degree of shock) under field conditions.

The Warner Institute for Therapeutic Research makes available to investigatorsthroughout the country the facilities of a large research organization with departmentsspecializing in all of the basic branches of the medical sciences.

THE FIFTH CLEVELAND MEETING OF THE AMERICANASSOCIATION FOR THE ADVANCEMENT OF SCIENCE

AND ASSOCIATED SOCIETIESEdited by Dr. F. R. MOULTON

PERMANENT SECRETARY

FROM September 11 to 16, 1944, the one hundredand eleventh meeting of the American Associationfor the Advancement of Science was held in Cleve-land, Ohio. Four meetings of the association hadpreviously been held in Cleveland, the first in 1853and later ones in 1888, 1913 and 1931. A meetingscheduled for Cleveland in 1852 was canceled becauseof an epidemic of yellow fever that prevailed fromthe Ohio River southward. This was the only timein 96 years that a meeting of the association was

interfered with by disease, but during that intervalthere were seven years in which the association heldno meetings because of war. Five of those yearswere 1861 to 1865, inclusive, when those who tt-gether had won their political freedom became fora time bitter enemies; and the remaining two were the

years 1942 and 1943, when nearly all the world wasat war.Only 43 papers were presented at the Cleveland

meeting in 1853, and 215 in 1888. In 1913 the num-ber had increased to 813, and in 1931 to 1,830. Atthe recent meeting the number of addresses andpapers had declined to fewer than 1,000 because ofthe many distractions due to the war. The member-ship of the association in 1853, 1888, 1913 and 1931was 940, 1,764, 8,333 and 19,059, respectively. Thisyear at a corresponding date was 25,000, in roundnumbers.

SOME GENERAL IMPRESSIONSFirst on the list of general impressions of the Cleve-

land meeting is that it was much better than any one
