FRIENDS of Professor Chandler presented in 1910 to Columbia University a sum of money which constitutes the Charles Frederick Chandler Foundation. The income from this fund is used to provide a lecture by an eminent chemist and to provide a medal to be presented to the lecturer in further recognition of his achievements in science. Previous lecturers on this foundation were L. H. Baekeland, W. F. Hillebrand and W. R. Whitney. The lecturer this year will be Frederick Gowland Hopkins, professor of biological chemistry, Cambridge University, England. The Chandler Medal will be presented to Dr. Hopkins in order to recognize his pioneer and very valuable work in the study of food accessories, such as vitamines. Professor Hopkins' subjects will be “Newer Aspects of the Nutrition Problem." His lecture will be in Havemeyer Hall, Columbia University, on the evening of April 18.

Dr. A. J. LOTKA, who is working as a guest in the department of biometry and vital statistics of the school of hygiene and public health of John Hopkins University, gave in April a series of four lectures on “ The dynamics of evolution and the foundations of physical biology."

SIR WALTER FLETCHER, secretary of the Medical Research Committee of Great Britain, will deliver the Tenth Harvey Society Lecture at the New York Academy of Medicine, Saturday evening, April 16. His subject will be: “ The state's relation to medical activities in Great Britain."

DR. HERBERT HAVILAND FIELD, who in 1895 founded at Zurich the Concilium Bibliographicum, died suddenly of heart disease on April 5, at Zurich, where he had lived. He was born in Brooklyn in 1868, graduated from Harvard in 1888.

DR. THOMAS BENJAMIN DOOLITTLE, of Branford, Conn., said to be the originator of the first telephone switchboard and associated in the organization of the original Bell Telephone Compnay in Boston, died on April 4, at

the age of eighty-two years. Dr. Doolittle in 1898 received the Edward Longstreth medal from the Franklin Institute of Philadelphia for developing the process of producing handdrawing copper wire.

DR. ALFRED DOOLITTLE, professor of mathematics and instructor in astronomy at the Catholic University since 1898, died on February 23.

We learn from the Journal of the Washington Academy of Sciences that Mr. Frederic Perkins Dewey, assayer of the Bureau of Mines of the Treasury Department, died on February 10, in his sixty-sixth year. Mr. Dewey after graduation from Yale University became instructor in chemistry at Lafayette College. From 1881 to 1889 he was connected with the U. S. Government, first as chemist with the Tenth Census, then as mineralogist with the Geological Survey, then as curator in the National Museum. After 24 years in chemical and metallurgical patent practise he became assayer of the Mint in 1903.

DR. E. BÉRANECK, professor of biology at the University of Neuchâtel, has died at the age of sixty-one years.

The death is also announced of Dr. León Becerra, chief health officer of Guayaquil, Ecuador, a member of the Rockefeller commission studying the yellow fever situation.

A COURSE of four public lectures on the history of plant delineation was given during March in the botany department of University College, London. The first two, on the art of the ancient empires and the dark and middle ages, was delivered by Dr. Charles Singer, and the other two, bringing the subject down to recent times, by Dr. Agnes Arber.

The United States Civil Service Commission announces an examination for the position of scientific assistant in the U. S. Bureau of Fisheries at $1,200 (plus $20 a month), to be held on April 27. Applicants will be rated chiefly upon zoology in its relation to the fisheries, and general biology.
