w- f AcreoNAr~o AROLEMShere's help for youT HIS tireless servant in your laboratory will automatically
collect any number (up to 200) of rigidly controlled samplesof predetermined fluid volumes. Each collected sample maycomprise any number of drops from one to four hundred. Aseach separate sampling is completed, the carriage automat-ically advances to repeat identical collections consecutivelyuntil the whole fractionation has been made.
All you have to do is to set it up for the conditions of thechosen experiment, short or long, and then leave it alone.The machine will plod along without attention hour after hour,all day (and night) long. When the job's done, it will shutitself off.
The Technicon Fraction Collector has been thoroughlytested in actual laboratory installations, where it has proveninvaluable to busy research staffs. We shall be happy to sendyou details.
Ref. Chromatography of Amino Acids on Starch Columns-W. H. Stein and S. Moore, Jrnl. hol. Chem. 176, 337,(1948)
' savestime and laborrelieves laboratory staff of the fretful and time.consuming chore of froction-cutting: releases workersfor other duties.
' triples work outputyou can run it twenty-four hours a day, continuously,to triple fractionation output as compared with an 8hour laboratory day.
' gives greater resolutionby collecting a large number of small fractions,rather than a few gross *nes, you'll get more datafrom a given fractionation, e.g. a chromatogram, ora fractional distillation.
'assures accuracybecause the Possibility of human error is automati-cally ruled out. Now fraction-collection becomes a
straightforward mechanical procedure.

Here is a new text for a standard course in statistical theory with a calculus prerequisite.The author first develops the necessary concepts and models of probability theory and thenproceeds with distribution and sampling theory. This leads to thorough exploration of the twomajor problems of scientific inference: the estimation of quantities and the testing of hypotheses.

With all the precision and qualitytraditionally associated with the name
Leitz, these improved Medical Mkroscopes embodythe latest advancements optical science can provide. Stands
are larger, yet lighter, with a longer bearing surface for the focusingmotion. Both coarse and fine adjustment are easier working, offer greatestaccuracy yet devised. New, built-in mechanical stage with low-set driveson a common axis, traversing area 3" x 2", means easier, smoother opera-tion. New substage condenser with swing-out upper element permits theuse of all tenses from lowest to highest magnifications. The oil immersionens 1/12th, N.A. 1.30, lOOx is anti-reflection coated for maximum definitionand better color rendition.

KERN Full-Circle PolarimeterIts three-part field of vision facilitatesadjustment and assures precision.
Ideally suited for chemists, physicians, hospitals andresearch laboratories for the determination of sugar andother optically active substances, the Kern Full-CirclePolarimeter has its field of vision divided into three parts-areas of equal illumination bound the contrasting cen-tral portion-unlike most standard polarimeters in whichthe field is divided into two semi-circular areas. Its full-circle scale permits rotation measurements up to plus orminus 180° and, with the vernier, enables readings of0.05° and estimations of 0.010. For small angles thesource of illumination may be daylight or electric bulb.Greater rotations are determined under sodium light.For further information write for our Kern Bulletin.71-792 Kern Full-Circle Polarimeter, equipped withthree tubes, 100, 200 and 95.04 mm. in length; in hard-wood cabinet; Each ............. $333.65

Less Adjusting ... Less Time loss.. . Better ResultsYou merely set the projector as indicated by a translucentchart (easily legible in a darkened room):calibratedfor a wide range of Micro Tessar and Achromatic Objec-tives (72mm-4mm)-giving you simple, accurate, com-
- plete coverage of all general micro-projector problems.THE CHART shows the proper settings; saves time.
PERMANENT ALIGNMENT of optical parts insures accuracy, eliminates "fiddling."You'll appreciate the many other outstanding advantages of the Model AA Micro.Projector that make it easier to use-to meet your most exacting requirements.
