Of the fundamentals of the subject matter of chemistry listed by Mr. R. W. Oshorne3' in a report on this topic, this course provides for every one the 42 applications; for 9 out of the 11 types of chemical change; for 14 out of the l(i theoretical topics; and for 9 out of the 13 laws.

We have attempted to outline a course which, in Dr. Gordon's words, "shall tell what chemistry has done and is doing, hut which shall not neglect an explanation of how it is done." It would seem to be impossible to give an adequate appreciation of chemistry without giving a t least a minimum understanding of the principles and methods of chemistry.

Recommends Cancer Centers for U. S. Organized cancer centers should he established hy the U. S. government, where full-time specialists and research workers will devote themselves to the study of this disease and acquire special skill in its treat- ment.

This recommendation has just been made to the Senate Commerce Committee by Dr. Ellice McDonald, research worker of Philadelphia.

A special cancer sub-committee of the Senate Commerce Committee will hold hearings soon after the return of the Senate the latter part of August, on the Harris resolution recently passed, calling for the investigation into the whole subject of cancer work with a view to discovering what the United States government should do to further it in this country.

Dr. McDonald's letter calls attention to the cancer work done by the British Empire and Belgium.

In Belgium the requiren~ents for a grant for a cancer center are: 1. Complete surgical service with facilities lor consultation for cancer patients. 2. Installation of machines for deep X-ray therapy, consisting of a t least two

pieces of apparatus, with a minimum capacity of 200 kilovolts. 3. An amount of radium of not less than 500 milligrams. 4. A laboratory where research work, examinations, and necessary analyses for

diagnosis and treatment shall he carried out. In Great Britain, Dr. McDonald points out, financial assistance is given cancer

research centers in order to keep them a t maximum eficiency. Also individual cancer research workers are given financial support, under approved conditions.-Science Service

Science Most Popular High-School Subject. Declaring science to be one of the most popular subjects in the high school, Prof. Francis D. Curtis, University of Michi- gan, told the Science Section of the National Education Association a t its Atlanta meeting:

"The past twenty years have witnessed remarkable ndvanccs in the improvement of methods and materials for science teaching. These advancco have been due to several causes hut chiefly to the influence of educational research in helping to determine subject matter and teaching methods better suited to the individual pupil."

Prof. Curtis further explained the popularity of the subject of science by calling attention to the fact that the recently adopted courses in general science give the high- school students an all-round practical training which could not be obtained from the special scicnccs as formerly taught.-Srienre Service
