The Committee has succeeded in locating all the Rumford medals 

 which have been awarded, and has procured casts or photographs from 

 which replicas can be made at any time. 



At the meeting of Nov. 8, 1911, the Committee made a change in 

 the requirements as to the publication of papers embodying the re- 

 sults of researches aided from the Rumford Fund. The rule as modified 

 now reads, " Persons carrying on researches with the aid of the Rum- 

 ford Fund should submit to the Academy an account of their researches 

 not less complete than that published elsewhere. These researches 

 may be published in any place or form, with the proviso that due rec- 

 ognition be made of the grant." 



At the meeting of the Committee held on February 14, 1912, it was 

 unanimously voted for the first time, and at the meeting held on 

 March 13 it was unanimously voted for the second time, to recommend 

 to the Academy the award of the Rumford Premium to Frederic Eu- 

 gene Ives for his Optical Inventions, particularly in Color Photogra- 

 phy and Photo-engraving.
