This prism is a reject, although the user of the refractometerfor which it was designed probably could not detect a singlefault in its performance. But, merely "good enough" falls belowBausch & Lomb standards.

These standards, based upon rigid inspection, give no quarterto inaccuracy. This is one of many reasons why you can placeyour trust in the uniform high quality of B&L instruments.

For your next instrument select one that bears the B&L trade-mark. Write concerning your optical instrument problems, toBausch & Lomb Optical Co., 642 St. Paul Street, Rochester, N.Y.

Revised and EditedBy S. Dana Weeder, M.D.

Formerly Instructor in AnatomyUniversity of Pennsylvania

Thoroughly revised, this successful textbookpresents a clear and concise account of the prin-

- ciples of human anatomy and physiology.The sections describing the stomach, colon and

sympathetic .nervous system have been expandedconsiderably, and the discussions on lymphaticdrainage and physiology of the spleen have beenbrought up to date.

Chapters on the origin and development ofblood cells and the endocrine system have beenrewritten and in the chapter on vitamins emphasishas been placed on practical considerations.Many illustrations were re-made and new ones

added. 283 Illus. 490 Pages. $2.75

THOROUGHNESS is an outstanding feature of thisnew book. Its sound, clear treatment of the essentialprinciples provides an adequate foundation for moreadvanced work on the subject.Motion is the theme around which the presentation isbuilt-motions of a body, motion in media, motions ofelectrons, etc. Besides the fundamental topics, othersof a general, present-day interest to students are given,such as the gyroscope, the radio, and electric c a 1machinery.A comprehensive teaching equipment is included.Throughout, close correlation has been kept betweentheory and laboratory. Numerous diagrams and photo-graphs add clearness and interest. The only prerequi-sites are high school algebra and geometry.

Why Smash Atoms?By ARTHUR K. SOLOMON

ATOM-SMASHING is today one of the mostimportant activities of scientists. Dr.

Solomon here explains the work of one typeof atom-smasher, the cyclotron, and de-scribes the transforming effects of atom-smashing on the sciences of physics andchemistry, as well as in medicine. Hemakes clear to the layman the nature, pur-pose, and results thus far of these epoch-making advances. This is popular sciencein the best sense of the term, a volume thatreveals to the non-scientific reader thegreat sweep of modern research. Fullyillustrated.

TO MEET THE LATEST STANDARDSOF MILK ANALYSIS CastIncubators

Uniformity of temperature through-out the incubator is a vital factor

in milk examination.

The A. P. H. A. recommends 37°C at all levels in the incubator, with atolerance of + or - 1°C. That is more liberal than the tolerance of CastlePrecision Incubators which have always operated with constancy of + or- °C and uniformity of + or - 7°C, under full load conditions.

They are easily maintained because of the efficient heat distribution andlarge reservoir of heat which features the Castle Incubator.

22 Gallons of warm water, accurately controlled, provide thousands ofcalories of reserve heat to quickly restore heat loss occasioned by open-ing of door. Heat is transmitted by interior radiation, rather than byconvection, hence less variation throughout the loaded chamber. Onethermometer is sufficient for accurate temperature measurements. Tem-perature inside incubator is unaffected by changes in room temperature,if below operating range.Illustrated is Castle Incubator, Model 554, recommended for milk analy-sis by the agar plate method. Other models for various bacteriologicalapplications and in various capacities are available. Write-

AMERICAN ASSOCIATION FOR THE ADVANCEMENTOF SCIENCE

PRELIMINARY ANNOUNCEMENT OF THE SEATTLE MEETINGEdited by Dr. F. R. MOULTON

PERMANENT SECRETARY

FROM June 17 to June 22, inclusive, the associationwill hold its summer meeting in Seattle, Washington,in cooperation with the Pacific Division. This will bethe one hundred sixth meeting of the association andthe twenty-fourth meeting of the Pacific Division. Ontwo previous occasions the Pacific Division met inSeattle, the first in 1920 and the second in 1936.Twenty-seven affiliated and independent societies willparticipate in the Seattle meeting.The fact that the association will not meet elsewhere

than in Seattle this coming June adds nothing techni-cally to the dignity of the meeting, for every meetingof the Pacific Division and of the Southwestern Divi-

sion is a meeting of the association, and might well beannounced as such. The vast size of our country makesit advisable to have administrative machinery fororganizing and holding meetings on the Pacific Coastand in the great Southwest. The officers of the PacificDivision and the members of the association residentin its territory will be primarily responsible for themeeting in Seattle. The association refrains from hold-ing a meeting elsewhere simply to encourage its mem-bers from the East to go westward and become betteracquainted with their western colleagues. Many scien-tists from the Pacific Coast attend scientific meetingsin the East; return visits will also be advantageous.
