818 PROCEEDINGS OF THE AMERICAN ACADEMY 



one for the medal at this time. The Rumford Committee has been pre- 

 sented by Professor Marcou with copies of forty-eight letters written by 

 Count Rumford to Professor Pictet of Geneva. The committee voted to 

 recommend to the Academy that it authorize the printing at the expense 

 of the Rumford Fund of the following four papers, and that a sum of 

 $25 be appropriated for illustration of these papers. 

 The titles of these papers are as follows : — 



1. Thermo-electric Interpolation Formula;, by S. W. Ilolman. 



2. The Melting Points of Aluminum, Silver, Gold, Copper, and Plati- 

 num, by S. W. Holman with R. R. Lawrence and L. Barr. 



3. Pyrometry : Calibration of the Le Chatelier Thermoelectric Pyro- 

 meter, by S. W. Holman. 



4. Calorimetry : Methods of Cooling Correction, by S. W. Holman. 

 The committee voted to authorize the publication in the American 



Journal of Science of a preliminary account of an investigation on the 

 thermal conductivities of certain kinds of stone, by Prof. B. O. Peirce 

 and Dr. R. W. Willson. Professor E. H. Hall's paper on the Thermal 

 Conductivity of Mild Steel was presented to the Academy, January 8, 

 1896, and has been published by the aid of the Rumford Fund. 



It is the desire of the Committee that the vote of the Academy at its 

 last annual meeting to appropriate from the Rumford Fund the sum of 

 one thousand dollars, to be expended at the discretion of the committee 

 in aid of investigations in light and heat, — payments from the sum to 

 be made on the order of the Chairman of the Committee, — should be 

 reaffirmed at the present meeting.

Chairman Rumford Committee. 



Report of the C. M. Warren Committee. 



I have to report that the recipients of the money granted by the 

 Academy from the Cyrus M. Warren Fund have been doing good 

 work. 



This statement is borne out very emphatically by the publications of 

 Professor Mabery, which are of a high order of excellence. 



At the last annual meeting it was voted by the Academy " that the 

 C. M. Warren Committee be requested to consider the propriety of np 

 propriating $50 from the income of the C. M. Warren Fund for the 

 purchase of books relating to chemical research."
