President's Address.

— 42°-3 C, cuprite at --4°'3, and beryl at — 4°'2. Beryl, when heated, 

 unlike ealcite, contracts in the direction of its axis, and expands in a 

 direction making right angles with the axis. Quartz, rutile, cassiterite, 

 spartalite, corundum, and hematite were found to expand in every direc- 

 tion when heated ; but in each case the expansion in the direction of the 

 principal axis was different from the expansion in a direction at right angles 

 to the principal axis. 



M. Fizeau is also the author of many other important researches — on 

 Moser's images, on photography, on the automatic engraving of photogra- 

 phic images on copper, on the interference of rays of heat, on electricity 

 and the velocity of its propagation, and on the position of the plane of po- 

 larization of light reflected from striated metallic surfaces. 



Professor Miller, 

 I have to request you to transmit this Medal to Monsieur Fizeau, in 

 testimony of our interest in his researches and our high respect for his 

 merits, which you have yourself been especially instrumental in placing in 

 a clear light before the Council.
