We regret to record the death, through an 

 accident, of Professor J. B. Johnson, dean of 

 the College of Engineering of the University 

 of Wisconsin. Born at Marlboro, Ohio, in 

 1850, Professor Johnson graduated from the 

 University of Michigan in 1878, and later 

 served as civil engineer on the United States 

 Lake and Missouri River Surveys. He was 

 called to the chair of civil engineering at 

 Washington University, St. Louis, in 1883. 

 While in St. Louis he conducted a large test- 

 ing laboratory, at which the U. S. timber 

 tests were made. In 1899 he accepted the po- 

 sition he filled at the time of his death. He 

 was the author of 'The Theory and Practice 

 of Surveying,' 'Modern Frame Structures,' 

 'Engineering Contracts and Specifications,' 

 'Materials of Construction,' etc. He was a 

 member of the London Institution of Civil 

 Engineers, the American Society of Civil En- 

 gineers, the American Society of Mechanical 

 Engineers and a fellow of the American As- 

 sociation for the Advancement of Science.

We learn from the Bulletin of the American 

 Mathematical Society that the Scientific 

 Society of Harlem has proposed, as the subject 

 for its prize in 1903, the investigation of the 

 Japanese mathematics of the middle of the 

 seventeenth century, and that the subject of 

 the prize competition for the present year of 

 the Societe Scientifique of Brussels is 'to make 

 a critical study of the works of Simon Stevin 

 on mechanics, comparing them with those of 

 Galileo, Pascal and other men of science of 

 the same period.' 



The optical works of John A. Brashear Co., 

 Ltd., have completed the 37j inch mirror for 

 the reflecting telescope to be used by the D. O.

 the southern stars in the line of sight. It is

 sail from San Francisco within the next sis 

 weeks.
