and it will be necessary to continue it for a number of years before 

 it will be completed. 



Two other researches for which the aid granted was employed were 

 begun in September, with the assistance of Dr. Herman C. Cooper 

 and Mr. Yogoro Kato. 



Theo. W. Richards, Harvard University. Grant No. 41. For in- 



vestigation of values of atomic weights, etc. $2,500. 



Abstract of Report. — Professor Richards has submitted a memoir, 

 about to be published by the Carnegie Institution, containing the 

 records of his experiments on a new method of determining com- 

 pressibility. By means of this method the compressibilities of 

 bromine, iodine, chloroform, broraoform, carbon tetrachloride, phos- 

 phorus, water, and glass have been determined over a range of 700 

 atmospheres. 



Besides the continuation of the preceding work, several other in- 

 vestigations are in progress, assisted by this grant. One of -these 

 concerns the effect of pressure on the electrochemical solution ten- 

 sion of metals ; another concerns the heat capacity of solutions ; 

 and another concerns the atomic weight of sodium. 



J. Bishop Tingle, Illinois College, Jacksonville, 111. Grant No. 40. 

 For continuing iitvestigations on the derivatives of camphor and 

 allied bodies. $500- 



Abstract of Report. — The work under this grant was not begun till 

 late in the summer. A number of bases have been tested as to their 

 power to undergo condensation with camphoroxalic acid and its 

 ethylic salt. Experiments have also been made to obtain further 

 information as to the possible presence of hydroxyl groups in cam- 

 phoroxalic acid, with encouraging results. 



Engineering. 



W. F. Durand, Cornell University, Ithaca, N. Y. Grant No. 64. 

 For experiments on ship resistance and propulsio?t. $4, 120, 



Abstract of Report. — Professor Durand reports that certain equip- 

 ment necessary for the conduct of the experiments was completed 

 early in the spring. Experiments in connection with the work on 

 propellers was begun, and all of the work of observation required 

 for the complete determination of the performance of thirty-five
