managing editor: A. D. Kuzovkovtranslated from Russiatn

A new monthly covering a wide variety of research into problems inthe development of new drugs for the treatment of malignant neo-

plasms and cardiovascular, neuropsychic, viral and other major dis-eases. It covers both experimental methods and research as well as

practical achievements in the field. Many articles will be devoted totrends in the pharmaceutical chemistry industry, quality of manufac-tured drugs, methods of analysis, preparation and control. In addition,economic, organization, production and planning problems will also bediscussed. The most urgent questions concerning the structure andbiological activity of drugs, the technology and apparatus of drug pro-

duction, and other advanced areas of research and engineering willbe covered. This important journal is of wide interest to chemists, phar-macists, biochemists, biologists, physiologists, medical research workersand all those concerned with the pharmaceutical industry.SUBSCRIPTION VOLUME 1 (12 ISSUES): $80.00(OVERSEAS SUBSCRIBERS: PLEASE ADD $5.00'SINGLE ISSUE S30.00 SINGLE ARTICLE: $15.00

The Image-Splitting Measuring Eyepiece

XThree hundred and twenty-

seven years ago, WilliamGascoigne of Yorkshire con-

structed a micrometer meas-

uring device suitable for use

in the relatively crude opti-

cal instruments of that day.M-dtficateon of Gascosgne'Micrometer, Since 1639 many refine-

Circa 1700 4

ments have been made upon

Gascoigne's achievement but these were refinements only. The first basicadvance in microscope measurement technique occurred only recently in1962 with the introduction of the Vickers-A.E.I. Image-Splitting MeasuringEyepiece. v The image splitting technique makes obsolete (for nearly allpurposes) Gascoigne's family of filar micrometers and eyepiece graticules.The image splitter is much more accurate. It is faster and more convenient

to use. It has an entirely unique capability for instantaneous, multiple com-

parative measurements. v Nearly one thousand Vickers Image Splittersare now being used by your colleagues and competitors. Here are just a fewof the things it can do for you.

* Measure with accuracies up to better than 0.1 micron (0.000004")* "Dial in" sizes so that objects anywhere in the microscope field can bechecked for conformity without measurement.

* Make particle size analyses without measurement.

* Measure moving or vibrating objects.* Measure without the possibility of parallax error or errors due to micro-scope instability.

If accurate and fast measurement techniques are essential in your work,please let us know. We will immediately send our descriptive brochure.
