_ Academy of Sciences.—Distribution of Prizes, 411 
Academy has already four times awarded the prize to this astronomer 
for the discovery of the five planets, Thetis, Proserpine, Bellona, Lewco- 
thea, and Fides. 
The prize for Mechanics was awarded to Mr. Giffard for the inven- 
tion of a new feeding apparatus for steam boilers, which he ealls an 
“automatic injector.” “The report; made by Combes, gives great praise 
to this apparatus. The injector very advantageously replaces the feeding 
nig of steam boilers. In addition to the fact that it avoids all loss of 
t, other than that which results from the cooling of the exterior of 
the tubes in which the steamy and hot water circulate, the absence of any

furnaces 
iven Mr. Giffard a hint which has led him to the invention for whick 
Mr. Giffard, who is a f st spirit, is known in France 
; ’ person of very earnest spirit, 1s a 
by his attempts at guiding balloons. Some years since he obtained 
evident results in directing them, since he succeeded in making his bal- 
to continue his researches upon this point, Giffard was not discouraged. 
nd representing himself as 
martyr to an idea, he left balloons for the 
pursuits. 
Physical. sciences —A prize has just been -divided between Daubrée, 
Dean of the Faculty of Science at Strasbourg, and Delesse, mining en- 
gineer at Paris, The question pro for competition was in respect 
« the Meta ism of Rocks. The report of the eommittee will not 
wnvey to the readers any more knowledge than they have already ob- 
‘ined from this Journal which has often made mention of the labors of 
Messrs, Delesse and Daubrée. P Son 
Pic Prize for experimental Physiology has been awarded to Pas _
