you needn't put up with"shoebox"' lblock filing

The "Lab-aid" paraffin block filing cabinet is finishedto match al other types of "Lab-aid" files, and stacksinterchangeably with any of them. Here is is stackedupon a vertical microslide file with In drawers.

Ask for a six-month-old paraffin block in many an

otherwise well-ordered laboratory, and the hunt's on.

Likely as not it means hours of prowling through a

weird behind-the-scenes jumble of dusty, dog-earedcartons . . . trying everyone's temper, taking every-

one's time, piling up hidden costs.That's all out now, with this new "Lab-aid" block

filing cabinet. You file your paraffin blocks in small,shipshape, white cardboard boxes, which come invaried sizes to accommodate all sorts of blocks, how-

ever irregular or out-sized. The boxes knock down,but spring to shape in a moment, so they re no

storage problem. They're so proportioned thatthey fit snugly, row on row, in the shallow steel

drawers.The all-steel cabinet holds ten drawers, equipped

with combination drawer-pulls and label-holders ateach end. Each drawer will accommodate a gross ofthe 11/2" boxes: other sizes in ratio (see the filleddrawers above). Multiply that by ten and you'vesome idea of the large capacity of this compact sec-

tion (it's only 19" square by 12" high) . That'sbecause there's no waste space . . . every cubic inchis a filing inch.

Gardner's FUNDAMENTAiS of NEUROLOGY

Stresses the principles of the subject!

F ROM his wide experience as a teacher Dr. Gardner knowsvery well that principles are of prime importance to the

student beginning the study of neurology. His aim in thispopular text, therefore, is to explain, to clarify and to simplify-he succeeds admirably in avoiding the tendency to confusethe reader with a mass of unrelated anatomical data and com-plicated physiological events.

He covers the field with neatness and dispatch and makeshis material understandable even to the student who has only aminimum background in biology. Basic neuroanatomy andfundamental physiology are discussed fully but concisely. Therelationships of psychology to the higher nerve centers are com-petently handled.

The results of experimental work on animals are includedin numerous instances for comparative purposes, and clinical ap-plications are introduced wherever they may help clarifystudent understanding.

CWhy wooden cages

instead of steel?

Steel would be more durable, but our care-ful checking over the years proves that lab-oratory animals breed better, maintainbetter health in wooden cages.

These cages are hung from the ceiling-donot touch the floor-to minimize insect in-festation. This is another example of thecare that produces dependable uniformityin the CF strains of mice, rats, and guineapigs, and explains why they are the choiceof so many leading research laboratories.

HISTOPATHOLOGY OF IRRADIATION FROM EXTERNAL AND INTERNAL SOURCES

Edited by WILLIAM BLOOM, M.D., Department of Anatomy, The University of Chicago.National Nuclear Energy Series. Manhattan Project Technical Section. Division IV.Volume 22-I. 848 pages, $8.00

*This is the first volume from the Plutonium Project Record (Division IV) describing thehistopathological and cytological effects of total-body irradiation by a wide range of radio-active agents. It compares the histological changes that result from various types of radiationoriginating externally and internally. It also gives aids in establishing "tolerance levels" tovarious amounts of radiation. The book covers a wide variety of experiments and givesdetailed information relative to techniques and materials.

ELEMENTARY PHOTOGRAPHY. New 2nd editionBy GUILFORD G. QUARLES, The Pennsylvania State College. 345 pages, $4.50

* As before, this well known text provides a treatment of photography between the very ele-mentary ones and those of an advanced technical nature. Thus the book assumes no previousknowledge of the subject, and care has been taken to make the new edition even more easilyunderstandable to the student and more teachable from the point of view of the instructor.All material has been brought abreast with present-day developments.

FOREST PATHOLOGY. New 2nd editionBy JOHN S. BOYCE, Yale University. 526 pages, $6.00

* This successful book has been thoroughly revised. Much of it has been entirely rewritten toinclude a wealth of information on such topics as salt spray injury, Phymatotrichum root rot,phloem necrosis of elm, Adelopus needle cast of Douglas fir, septoria canker of poplars,canker stain of planetree, oak wilt, persimmon wilt, and several other rots. New material hasbeen added on the prevention and control of the deterioration of wood in service.

HISTORICAL GEOLOGY. New 2nd editionBy RUSSELL C. HUSSEY, University of Michigan. 465 pages, $3.75

* Gives the geological history of North America and its inhabitants throughout two billionyears of time. The book presents the outstanding events in the geologic history of NorthAmerica, emphasizing the development of life during various geologic periods. It covers theprinciples of evolution, and elaborates upon them as each group of vertebrates is introduced.This second edition has been simplified and contains an abundance of carefully chosenillustrations.
