The PANPHOT combines permanentlyaligned microscope, camera and lightsource in one convenient unit.

Universal Camera Microscopeyour|| |Only the Leitz PANPHOT enables you to switch from

microscopic observation to photo-micrography without moving* ~~~~~fromyour chair, for it's the only universal camera microscope

with operating parts for both functions right at hand. Changeover from one to the other is fast,simple, dependable. Now available to industrial and technical laboratories, the PANPHOT isa perfect combination of research microscope and reflex camera.The PANPHOT permits the use of transmitted light, reflected light, darkfield illumination andpolarized light. The permanently aligned light source provides a filament lamp for observationand an arc light for photo-micrography.Easy observation of the image to be photographed is provided by a large ground glass in the reflexmirror camera. The camera accommodates 3Y4" x 4'4" plates or cut film for black and white orcolor work.A full range of accessories is available to equip the PANPHOT for every phase of photo-micrography, photo-macrography and for drawing and projecting micro-images.

New (2nd) Edition

Gardner's Fundamentals of

NEUROLOGYNew (2nd) Edition. The continuing popularityof this book is due to the clear way in which theauthor presents the principles of neurology be-fore attempting to explain the details.Dr. Gardner's aim in writing this text is to givethe student a knowledge of the structure and func-tion of the nervous system, without confusing himwith a mass of unrelated anatomical data, physio-logical events, and signs and symptoms. The subjectis covered with neatness and dispatch and the textprogresses systematically from the development ofelementary fundamentals to more advanced andcomplex concepts. All the material is fully under-standable to the student who has had a minimumbackground in biology.

There is much new material in the New (2nd) Edi-tion on motor pathways, nerve conduction, cerebralcortex, etc. There are also 39 new illustrationsmaking a total of 223 illustrations on 142 figures.

This is a close-up view of a rack of microslidesundergoing staining on the Autotechnicon. Theprocess is completely automatic, and geared tosplit-second timing. The slides are now descend-ing into one staining-fluid beaker: at the precisemoment when the required immersion period hasbeen completed, they will be promptly raised,and rapidly shifted to the next station in thesequence . . . automatically, infallibly. Duringimmersion the slides are rotated gently within thefluid, thus assuring rapid, even stain permeation.

Any technique prescribed by the pathologistmay be employed. Once the master dial has beenset for the correct time intervals, the method maybe repeated time after time, without the minutestvariation, and independent of any supervision.Each batch of slides' put through is stainedin exactly the same way, resulting in unvaryinguniformity.Autotechnicon staining is not only convenient,

dependable, time-saving. . . it produces "Sunday-best" slides . every day.
