10. On the Alloys of Copper and Zinc ; by Frans H. Storer. (From 
the Memoirs of the American Academy, [N.S.,] vol. viii, p. 27),* Cam- 
bridge, 1860, pp. 32, 4to. 
In the words of the author :—“ This research was undertaken in order 
to ascertain what, if any, definite chemical compounds could be detected 
among the alloys of copper and zinc.” 
“ Several chemists had already been led to believe in the existence of 
Mr. Storer has prepared a large number of alloys of copper and zine 
containing different proportions of these ingredients, by methods which 
he has described in detail, and has found that they may all be crystallized 
by piercing the crust which forms upon the partially cooled molten metal 
and then quickly pouring off those portious of the latter which are 
portion of copper since they are liable to pass through a pasty plastic state 
similar to that assumed by zinc or soft-solder while solidifying. 
. The edges of all of them are rounded. The octahedra are in 
general more largely developed upon one side than the other, apparently 
upon the side from which the last drippings of the melted metal fell.
