Far superior in convenience to an ordinary wooden stool, theFisher Laboratory Utility Stool is immediately adjustable in heightto suit the needs of different workers at low tables or higher benches.It is made of heavy gauge pressed steel and is unique because of itsintegral locking clutch mechanism. This patented feature permitsquick changing of seat level (between 17" to 26" from floor) andautomatic holding of the seat at the height to which it has beenraised.

The seat of this Stool revolves so that you glide (rather than"twist") into and out of any desired working position.

No tools are required to place the Laboratory Utility Stool inuse; none are necessary to adjust its height, and there are no roughsurfaces to snag clothing. Each, $10.50

Millard and King'sHuman Anatomy and Physiology

Second Edition. This textbook represents one of the most significant contributions tothe teaching of elementary anatomy and physiology in print today. Outstanding for itssuperb balance and refreshing style, it covers the basic facts essential in the study ofhuman anatomy and physiology. Anatomical systems serve as a basis for the under-standing of physiological principles.

Such subjects as Pseudostratified Epithelium, Chemical Changes during Muscle Contrac-tion, and Sensory Mechanisms are fully discussed. The Physiology of the Muscle, theArterial Pulse, the Nerve Impulse, Cerebrospinal Fluid, etc., are presented with specialattention-to recent advances in knowledge. There are 44 new illustrations, bringing thetotal to 296.By NELLIE D. MILLARD, R.N., M.A., Instructor in Anatomy and Physiology, School of Nursing, Michael ReeseHospital, Chicago; and BARRY G.

Millard and Showers'Laboratory Manual of Anatomy and Physiology

A new laboratory manual designed to give the student actual contact with real objects ofnature. As he follows the clearcut directions for each experiment, he will find anatomyand physiology becoming much more than a mere theoretical discussion of structure andfunction. He will see actual tissues, nerves and arteries, will learn the interrelation ofevery function of the body, and be able to watch with understanding muscle action,respiration and circulation taking place in human specimens.

The exercises of this manual include the study of living animals, dissection of the rabbit,frog, the embalmed cat, guinea pig and butcher shop specimen; microscopic examinationof living and prepared tissues and investigation of physiological phenomena.By NELLIE D.

HAWK, OSER & SUMMERSONPractical Physiological Chemistry-12th EditionExtensive progress is the keynote of this famous text and laboratory guide. The style is straight-forward and understandable, written to instruct both the student and the physician. Among themany advances presented in the light of their clinical applications are included the modern con-cepts of protein structure and enzyme action, intermediary metabolism, the newly discoveredvitamins, antivitamins and antibiotics, etc.The new chapters dealing with gastric function, respiratory metabolism, blood chemistry, nutri-tion, deficiency diseases and the physiological availability of the vitamins are of special interest.Descriptions of laboratory procedures are lucid and concise and are accompanied by clinicalinterpretations of the findings in disease.Among the newer technics given special attention are: the Warburg method for the study oftissue respiration, microbiological assays for amino acids in vitamins, antibiotics (penicillin,etc.), polarography, manometric methods, and bioassays. A fundamental yet comprehensivediscussion of colorimetry, photometry, spectophotometry, fluorometry and turbidimetry is in-eluded in the chapter on blood analysis, and methods are described so that they can be adaptedto both colorimetric and photometric measurement.A series of new compounds of biochemical and clinical interest are presented in this edition-strepogenin, pteroylglutamic acid, the penicillins, avidin, neo-vitamin A, cholinesterase, etc.The broad academic and practical experience of the authors (Dr. P. B. Hawk and Dr. B. L. Oserof the Food Research Laboratories, and Prof. W. H. Summerson of Cornell University MedicalCollege, ensures the timeliness and scientific accuracy of this text).

Cyclotron Specialties Instruments are readily assembled into acomplete apparatus for the rapid and accurate determinationof radioactivity. They combine simplicity and economy with allimportant requirements of the most exacting investigatorsand have won recognition of the leading workers in this fieldthroughout the world ... in educational institutions, industrialplants, laboratories and hospitals.

For new workers, the use of a cathode ray oscillograph, givingan excellent visual pattern of the pulses, is recommended. The

counter set is fitted with amplifier and external connections for

this purpose. The Cyclotron 401-A Impulse Register is also

widely used by itself for high speed impulse recording or me-

chanical operation counting.

Cyclotron Specialties Instruments are quickly assembled intoa complete radioactivity apparatus...The sample to be tested Is placed in an ashing dish where its

radioactivity Is transmitted into the GeOger Tube through thelatters thin mica window. Impulses from the tube oar ampli-fied and extinguished by a First Stage. This pases the im-

pulses on to the Counter Set where they are ampflod, scdleon a scae of eight and Indicated on the Impulse Register.

Upjohn Co., Kalamazoo, Mich., use

this Micromax Recorder to show the

constant purity of the sterile, double-

distilled, pyrogen-free water which is

one oftheir products. Shown below

is the equipment's metal-boxed con-

ductivity-cell assembly.

F~~~~~ora ater

An overall check of the purity of water from any automatic

still is provided by a Micromax Recorder of the type shown

here.

This- instrument can warn the chemist or biologist against

such difficulties as using water before entrained air has been

swept out of the still. It also warns if improper or carelessoperation causes foaming or priming, and thus carries undis-

tilled water to the effluent. Regardless of cause, if the efflu-

ent isn't of the desired conductivity, the Micromax indicates

the fact,and can of course operate an alarm light or bell if

required.

One of the equipment's greatest advantages, in a large lab-

oratory, is that the automatically-drawn record chart gives

written proof of water purity.

Catalog EN-95 describes the equipment and will be sent

on request, but if you have a definite application in mind,

an L&N engineer will be glad to supply individualizedinformation.
