The average quantity used is. there- 

 fore, 2.1 per cent. It is, therefore, clear 

 that this method enables one to detect 

 and estimate approximately the quantity 

 of cedar wood oil in an admixture of 

 the two oils. Of course, further ex- 

 periments may show that slightly wider 

 limits are necessary in the figures, but if 

 this is so, it can only be to a very slight 

 extent, and would not alter the general 

 value of the process. In conclusion, I 

 may say that the 12 samples here dealt 

 with are of absolutely guaranteed authen- 

 ticity, for which I am able to vouch with 

 certainty.* 



THE HODQKINS FUND PRIZES. 



REPORT OF THE COMMITTEE APPOINTED 

 BY THE SMITHSONIAN INSTITUTION 

 TO AWARD THE HODGKINS FUND 

 PRIZES. 



The Committee of Award for the 

 Hodgkins prizes of the Smithsonian In- 

 stitution has completed its examination 

 of the two hundred and eighteen papers 

 submitted in competition by con- 

 testants. 



The Committee is composed of the fol- 

 lowing members : 



Dr. S. P. Langley, chairman, ex offi- 

 cio ; Dr. G. Brown Goode, appointed by 

 the Secretary of the Smithsonian Institu- 

 tion ; Assistant Surgeon-General John S- 

 Billings, by the President of the National 

 Academy of Sciences ; Professor M. W. 

 Harrington, by the President of the 

 American Association for the Advance- 

 ment of Science. 



The Foreign Advisory Committee, as 

 first constituted, was represented by 

 Monsieur J. Janssen, Professor T. H. 

 Huxley and Professor von Helmholtz ; 

 and after the recent loss of the latter, 

 Dr. W. von Bezold was added. After 

 consultation with these eminent men, the 

 Committee decided as follows : 



♦Read at the British Pharmaceutical Conference. 



First prize, of ten thousand dollars, 

 for a treatise embodying some new and 

 important discoveries in regard to the 

 nature or properties of atmospheric air, 

 to Lord Rayleigh, of London, and Pro- 

 fessor William Ramsey, of the University 

 College, London, for the discovery of 

 Argon, a new element of the atmos- 

 phere. 



The second prize, of two thousand dol- 

 lars, is not awarded, owing to the failure 

 of any contestant to comply strictly with 

 the terms of the offer. 



The third prize, of one thousand dol- 

 lars, to Dr. Henry de Varigny, of Paris, 

 for the best popular treatise upon atmos- 

 pheric air, its properties and relation- 

 ships. Dr. de Varigny 's essay is en- 

 titled: " L'Air et la Vie." 



After having performed the function 

 to which the Committee was called, as 

 announced by the circular of the Secre- 

 tary of the Smithsonian Institution, dated 

 March 31, 1893, which function did not 

 include the award of any medals, there 

 remained several papers to which the 

 Committee had been unable to give any 

 prize, but to which they had felt desir- 

 ous to give some honorable mention, 

 and on their representing this to the 

 Smithsonian Institution they have been 

 commissioned to do so, and also to give 

 certain medals of silver and bronze which 

 had been subsequently placed at their 

 disposition 



The Committee has decided that 

 honorable mention should be made of the 

 papers, twenty-one in number, included 

 in the following list, which also gives 

 the full names, titles and addresses of the 

 authors, and the mottoes or pseudonyms 

 which in four instances were employed. 

 To three of the papers a silver medal is 

 awarded and to six a bronze medal. 



HONORABLE MENTION WITH SILVER 

 MEDALS.
