To FacilitateFiltrations

Many me s f Aysis aowrecommend-the addition of smallamounts of filter pulp to expeditethe filtration of gelatinous precipi-tates ngdto. aid -in the retention of6ne precipitates.

WHATMAN ASHLESS FILTERTABLETS are the preferred sourceof pulp in many leading laboratory..ies. These tablets, made of hlighypurified pulp washed in HWF andHCl, break up easily in distilledwater to form a smooth even sus-pension which may be added to thesolution to be. filtered or ..poured onthe filter paper after it has been setin the funnel.

The use of pulp made fromWHATMAN ASHLESS TABLETSdefinitely expedites filtrations andspeeds up the work of busy- labora-.

By F. KLEIN. Translated from the 3rd German edition by E. R. HEDRICK and C. A. NOBLE.5Ax 8A, IX + 274 pages, 125 illustrations. $3.50

An invaluable work, serviceable alike to the university teacher and to the teacher in secondary schools.There is nothing comparable to it, either with respect to the skilfully integrated material, or to thefascinating way in which this material is discussed. Every teacher of mathematics should be acquaintedwith it.

"The work as a whole is a remarkable example of the distinguished apthor's mastery of the art of clearand stimulating exposition. We sincerely hope that it will have a. wide influence in arousing an active interestin a more serviceable preparation of our teachers." Bulletin of the American Mathematical Society.

TERMINAL PROGRAMS IN THE GRADUATE SCHOOLSBy Dr. CARL E. SEASHORETHE STATE UNIVERSITY OF IOWA

A TERMINAL program leading to the master's degreeis a program of study designed specifically on a one-or two-year basis as distinguished from the master'sdegree program leading toward the doctorate, whichis designed for the first year on a three-year basis.The terminal program is tailor-made, designed to fit

the individual needs of the student in relation to per-sonal and professional objectives. It is sponsored bya professor who gives particular attention to the or-ganization of terminal programs. It, therefore, be-comes student-centered as opposed to subject-centered.It represents a vocational or semi-professional bentbut should be distinguished from purely technologicalcourses and be dominantly of a liberal character but

with a vocational aim. The member of the staff whodirects the work takes responsibility for the maintain-ing of standards and a happy balance between con-centration in an area and reasonable spread of workwithin a chosen field, the securing of the privilegesinvolved and personal direction of the thesis. Thework on the thesis and the organized reading are de-signed to introduce the student to bona-fide graduatemethods of study. The terminal program ensuresadequate consultation between student and staff at thetime of registration and personal guidance throughouttoward a well-conceived objective.

The primary purpose of this type of organizationis the standardization of two types of master's de-
