atomic physics

Now for the first time a complete line ofversatile component units for radiationresearch equipment is available. Theseprecision units can be made up in a widevariety of instruments and systems tosuit your particular requirements; at thesame time they offer the economiesachieved by standardizing basic units.

These unique instruments include,among others, single and multichannelpulse height analyzers, an outstandingnew linear amplifier, coincidence andanti-coincidence analyzers, alpha, betaand gamma spectrometry detectors, con-tinuous and step-wise spectrum scanningequipment, and a five peak analyzer.

Bomer - The Vertebrate BodyThis up-to-date text offers a superior study of comparative anatomy.Dr. Romer's reputation as a scholar, teacher and writer alone pro-vides sufficient reason for hearty recommendation.

Featured in 7ihe Second Edition1. A wealth of illustrations help the student see beyond his own obser-

vation in the laboratory.2. Treatment is truly comparative, without overemphasis of the human

structure.3. Paleontological background serves as a check on the deductions and

assumptions made from the anatomy of living forms.4. Embryology is presented to establish an understanding of homologyand to remind the student of the time element in the stages of devel-opment.

5. Histological data show the basic materials of which gross structuresare composed and offer an appreciation of the function of glands andtissues.

6. Function of the vertebrate body is included to complete the pictureof anatomy, since organs are constructed in accord with theirfunction.

By ALFRED S. ROMER, Alexander Agassiz Professor of Zoology and Director, Museum of Compara-tive Zoology, Harvard University. 644 pages, 6" x 9", with 390 illustrations. $7.00. Second Edition!

Arey - Developmental AnatomyThis classic text is well known for its exceptionally clear and visualpresentation of embryology. Part I, General Development explainsfundamental concepts and the origin of the embryo. Part II, SpecialDevelopment discusses the differentiation of the cells into organs andsystems. Both function and structure are thoroughly covered. Part IIIis the laboratody manual. This is the only general text of its kind, thatincludes a laboratory manual. It studies the pig and chick embryosin detail.

Features of The Sixth Edition1. The arrangement of material is clear, concise and logical.2. The basic facts are discussed in large type for the general college

student and the more detailed and technical data are included insmaller type for medical and more advanced -workers.

3. Paragraphs entitled Causal Relations summarize pertinent informa-tion on the developmental mechanics of each organ or system.

4. 1552 outstanding illustrations make the text as clear as possible.They are clearly labeled and many are in color.

By LESLIE BRAINERD AREY, Ph.D., Sc.D., LLD., Robert Laughlin Rea Professor of Anatomy,Northwestern University. 680 pages, 6%" x 9%", with 1552 illustrations on 630 figures, many incolor. $9.50. Sixth Edition!

Performs complete blood counts automatic-ally in less than two minutes! Utilizing pre-cision electronic circuits instead of thehuman eye, the Arithmometer works auto-matically-you merely insert blood sample,push a button and read results on largedial. 3% accuracy whether you are countingred or white cells. Eliminates "checks", "re-peats", and doubt about vaidity of results.

LEITZ NEWFREEZING

MICROTOME

Considerably larger than our

standard freezing microtome, this

sturdily built instrument has built-in specimen and cooling arrange-

ments, thus eliminating all but one

carbon dioxide cable. Sections may

be cut at variable thicknesses from

2.5 to 50 microns. Adjustable ob-

ject clamps are available, as well

as paraffin and freezing stages of

50 and 35 mm. diameters. Guar-

anteed to give you better frozen

sections more rapidly.
