for ages 55-59, representing risks that 

 have been under observation for a longer 

 period. 



Special investigations in connection with 

 this experience show in general that there 

 is considerably more sickness among the 

 outdoor industrial classes than among the 

 indoor industrial classes and slightly more 

 sickness among the indoor industrial classes 

 than among the clerical and professional 

 classes. The amount of sickness in the 

 north and west is about the same and in 

 each case is less than in the south— while 

 the amount of sickness in large cities is less 

 than in the small toAvns. 



The following subjects were read by

Two Neglected Subjects of Social Econ- 

 omy, including interment and crema- 

 tion considered from sanitary and senti- 

 mental standpoints : by Mrs. L. Osborne 

 Talbott, Washington, D. C. 

 Relation of Death Bates and Birth Bates, 

 applying well known natural laws to the 

 explanation of sociologic phenomena, and 

 concluding that the far-reaching socio- 

 logic effects of the reduction of the birth 

 rate are reduction of death rate, survival 

 of the most intelligent, loss of physical 

 robustness, and growth of higher civili- 

 zation and democracy: Charles E. 

 Woodruff, U. S. A., Plattsburg, N. T. 

 The Brain and Education: Thomas M. 

 Balliet, New York University. The 

 main thesis being that while our knowl- 

 edge of the brain is too scanty to build 

 a theory of education on it, neurology 

 can throw many side-lights on educa- 

 tional problems.

Brief abstracts are given of all chemical

The appearance of this journal marks an 

 epoch in the progress of chemistry in America, 

 and is an achievement of which the American 

 Chemical Society may well feel proud. The 

 establishment of such a publication has been 

 made possible by the untiring efforts of the 

 editor. Dr. Noyes, and the loyal support of 

 more than 130 of the leading chemists of the 

 country who are acting as assistant editors 

 and abstractors either gratuitously or at a 

 merely nominal remuneration. The society is 

 to be congratulated also on the fact that it has 

 had the courage to undertake this publication 

 single-handed and without entering into 'en- 

 tangling alliances ' with any other organiza-
