At the meeting of the Royal Society, held

 ture on "Michael Faraday and the Foundations 

 of Electrical Engineering." Many of Fara- 

 day's original experiments were repeated, and 

 on the lecture table were some of the original 

 apparatus he employed, lent by the Royal In- 

 stitution, where all his work was done. The 

 Science Museum at South Kensington also 

 lent models and examples of early electrical 

 machines. 



Dr. Charles W. Waidner, chief physicist 

 of the Bureau of Standards, known for his 

 studies of temperatures and heat measuremsnts,

 sad duty to announce the death, on March 4, 

 of Associate Professor William Logan Wood- 

 burn, who for twelve years has been our col- 

 league in the department of botany at North- 

 western University. Born near Bloomington, 

 Indiana, in 1882, he prepared for college in 

 the near-by high school, completed the course 

 for A. B. at the University of Indiana in 1908, 

 was elected to the honorary societies of Phi 

 Beta Kappa and Sigma Xi, acquired the mas- 

 ter's degree by graduate work in 1909, and the 

 doctorate of philosophy in 1912 at the same 

 institution. During his twelve years at North- 

 western University, he proved himself to be a 

 conscientious, enthusiastic, and inspiring teach- 

 er, and a loyal, unselfish and sympathetic col- 

 league. As an investigator he carried to suc- 

 cessful completion and publication several 

 valuable research problems in cytology, large- 

 ly along the line of spermatogenesis in liver- 

 worts and mosses."

 Clark was born in Tyringham, Massachusetts, 

 a small hamlet in the Berkshire HUls, on

 Gottingen in 1857. In 1859 he held the chaii-

 ceived the degree of M. D. from the College
