A MEMOEiAL to Dr. D. B. St. John Eosa 

 was unveiled in the Post-graduate Medical

 which he was the president from its founda- 

 tion, in 1881, to his death in 1908. The bronze 

 tablet, which represents in relief Dr. Eosa in 

 academic robes, is the work of Mr. Henry 

 Merwin Shrady. 



Dr. John William Mallett, P.E.S., pro- 

 fessor emeritus of chemistry at the University 

 of Virginia and eminent for his contributions 

 to chemistry, died on November 7, aged eighty 

 years. 



Dr. John Monroe Van Vleck, professor of 

 mathematics at Wesleyan University from 

 1853 until his retirement as emeritus pro- 

 fessor in 1904, died on November 4, aged 

 seventy-nine years. 



Major General Egbert Maitland O'Eeilly, 

 U.S.A., retired, former surgeon general of the

Mr. Bradford Torrey, the American author 

 of books on natural history, has died at the

Mr. James B. Parker, of Oxford, known 

 for his work in archeology and geology, has 

 died at the age of seventy-nine years. 



Mr. William Bottomley, the nephew of 

 Lord Kelvin, who assisted him in his scientific 

 and engineering work, died on October 19,

The U. S. Civil Service Commission an- 

 nounces an examination for assistant chemist 

 in radio-activity, for men only, to fill vacan- 

 cies in the Bureau of Mines, at Washing-ton, 

 D. C, or Denver, Colo., at salaries ranging 

 from $1,800 to $2,160 a year. For the same

A Mental Hygiene Conference and Ex- 

 hibit was conducted at the New York City 

 College by the National Committee for Mental 

 Hygiene and the Committee on Mental Hy- 

 giene of the New York State Charities Aid 

 Association. Provision had been made for a 

 large public attendance, and physicians guided 

 parties through the exhibit every half hour, 

 afternoon and evenings. The exhibit, which 

 closed on November 15, was opened on No- 

 vember 8 with addresses by President Finley, 

 Dr. Lewellys P. Barker, Dr. James U. May

We learn from Nature that on October 16 

 a conversazione was held by the Eoyal Micro- 

 scopical Society in the great hall of King's 

 College, about four hundred fellows and guests 

 being received by the president, Mr. H. G. 

 Plinuner, F.E.S., and Mrs. Plimmer. The 

 object in view was, so far as practicable, to 

 gather together a series of exhibits which 

 would indicate the many uses, both in science 

 and commerce, to which the microscope is put 

 at the present time. In addition, the con- 

 versazione afforded an opportunity for those 

 engaged in microscopic work to show objects 

 of interest or to demonstrate the use of appa- 

 ratus or appliances for special purposes. 



The International Photometric Commis- 

 sion, commonly known as the " Zurich Com- 

 mission," was created by the International 

 Congress of Gas Industries which convened in 

 Paris in 1910. This commission, composed 

 of representatives from the various national 

 technical gas societies, with the cooperation 

 of certain of the national laboratories, has 

 been concerned with general questions of 

 photometry in addition to its more specific 

 functions in connection with the photometry 

 of the incandescent mantle. Inasmuch as 

 there has developed a wide-spread apprecia- 

 tion of the need of an international, thor- 

 oughly representative commission to deal with 

 general questions of photometry, and pos- 

 sibly also of illumination, it has been proposed 

 that the International Photometric Commis-
