DANIELS, WILLIAMS

and WORTHINGHAM'S

MUSCLE TESTING

THESE authors have met a definite need inwriting this new book. Here you will find

detailed data on muscle topography, musclefunctions, joint range and nerve distributions,adapted and applied for everyday use in manualmuscle examination and evaluation of musclestrength. Whether muscular weakness be theresult of disease, injury or disuse, the tests givenhere provide a basis for determining the exactdegree of weakness and for the prescribing ofmuscle reeducation or the planning of reconstruc-tive orthopedic surgery. In addition, they pro-vide a reliable means of measuring, from time totime, improvement of the conditions. The greatsimplicity and full fidelity of the 349 diagrammaticline drawings make this manual easy and con-venient to use at all times. (The study on whichthis manual is based has been aided by a grantfrom the National Foundation for InfantileParalysis, Inc.)By LUCILLE DANIELS, N.A., Director and Associate Professor of Physi-cal Therapy, Stanford University, MARION WILLIAMS, M.A., AssistantProfessor of Physical Therapy, Stanford University, and CATHERINEWORTRINGHAM, M.A., Director of Professional Education, The NationalFoundation for Infantile Paralysis, Inc. 189 pages, 8" x 10%", with 349illustrations. $2.50

Marshall-Lazier'sHUMAN ANATOMY

In revising this standard text of ele-mentary human anatomy, Dr. Lazier hasadded a wealth of important material.For example: The chapter on Bones andJoints has been changed to incorporatenew material on the vertebral column, the.spine and the joints. More adequatecoverage is given to the discussion of theribs, the skull and the arm bones. Inaddition, Dr. Lazier completely rewrote

and extensively expanded the chapteron the Muscles. 64 new illustrationshave been included to make a total of303, 13 of them in color.By CLYDE MARSHALL, M.D., formerly Assistant Professorof Anatomy, Yale R University. Revised by EDGAR L.LAZIER, PH.D., Associate! Professor of Zoology, Universityof California at Los Angeles. 418 pages, 5x" x 74", with303 illustrations, 13 in color. $2.50. New (3rd) Edition.

Rathbone's CORRECTIVE

PHYSICAL EDUCATION

,&Af MICROLUXA Highly Efficient UniversalMICROSCOPE LAMP

For :Visual Observation,Photomicrography, Micro-Projection

The Microlux yields the highest intrinsic light intensityobtainable with an incandescent light source. It is com-pact, consumes little current, and can be used on 110volt A.C. current.

The MICROLUX Provides TheseOutstanding Advantages:

* It con be used in photomicrography from low to highmagnification with the complete two lens condenser ofthe substage of the conventional medical microscope.After alignment, adjustment to the light system with the16mm objective, changes to objectives of shorter focallength-including the oil'' immersions-can be madewithout further adjustments of the entire illuminationsystem.* With each objective uniform illumination existsthroughout the field, and the intensity is sufficient forshort exposures even with a'green filter.* An aperture stop as well-as a field stop is operativefor the entire range of magnifications. The field of viewis remarkably flat on the ground glass.* For visual observation, a diffusing daylight filter isplaced in the filter holder.* For micro-projection, a projected image of satisfac-tory intensity approximately three feet in diameter canbe obtained with a 16mm objective.

* The short focal length of the condenser permitsoptical conditions for uniform illumination, even at highmagnification, to be met with the lamp placed relativelynear the microscope. This makes the lamp controls ecyIlyaccessible to the microscopist.

* The lamp can be tilted from a horizontal to an almostvertical position.* The light source is a special low voltage lamp of smallcurrent consumption and high illumination intensity.

* At maximum rheostat setting, the light is of propercolor temperature (32000 K) for use with KodachromeType B film without the need of auxiliary filters.

* Both condenser and lamp positions are adjustable forobtaining proper optical alignment.

ADDITIONAL MICROSCOPE ACCESSORIES

The Leitz Magarc... A carbonarc microscope lamp employ-ing an entirely new principle-feeding of the carbons ismagnetically controlled assur-ing continued positive per-formance throughout the lifeof the carbons.

The Leitz Micam Camera At-tachment . . . Light-weight, _sturdy, highly precise . . . at-taches to any microscope withstandard eyepieces . . . hasvertical ground glass forviewing and focusing. May beused for micro-projection.

Lens Performance Magnified 240XTHE new Photographic Lens Testing Pro-

jector, designed and built by B&L engi-neers, shows visually on a large screen the exactquality of image produced by the lens. To testthe Animar 8mm motion picture camera lens,Bureau of Standards test chart, covering thediagonal of an 8mm frame, is projected, by thelens being tested. The result is an image on thescreen at a magnification of 240 diameters . . .

approximately /4 inch magnified to 42% feet!The lens is focused to give the best possibledefinition at the center of the field. For thissetting, resolution is read at the center andmargins ofthe field. At the same time, variationsin focus from the normal value are read on a

dial gauge. Parfocality of these lenses is con-

trolled within a tolerance of ± .001". Excep-tionally fast, simple, and accurate, this method

insures uniformly high quality lens performance.Another method in progressive optical engi-

neering for testing performance of lenses-animportant factor in establishing American-made B&L photographic lenses as the ultimatein quality among photographers everywhere.
