crease the expense, whilst, by four or six such heating ap- 
paratus, with which sixteen to twenty-four pots can be 
constantly kept in operation, larger quantities can at once 
be concentrated than have ever been concentrated in the 
largest platina still, and that at only the sixth or eighth part 
of the cost, not reckoning the expensive repairs which a pla- 
tinum still requires from time to time. — Pharm Jour., Feb.,

Solubility of Iodine in Cod-Liver Oil. By Fleischmann. — 
In order to discover in what proportion iodine is soluble in 
the fatty oils, Fleischmann rubbed down one and a half gr- 
of iodine with a few drops of ol. jecoris aselli album, and 
found that it soon dissolved. The oil at first assumed a dirty 
brown color; but upon the addition of five ounces more oil, 
this color disappeared, and no difference could be observed 
between the pure oil and this mixture. — Pharm. Jour., from 
Buchnefs Repertorium, 1849, No. 11. 
White Enamel for cementing Earthenware and Glass. — 
Four parts of red lead, two parts of white sand, and three 
parts of crystallized boracic acid are to be finely powdered? 
washed, mixed, and fused in a Hessian crucible. The mass 
is then poured on a sheet of metal and finely triturated. The 
powder is applied with mucilage of tragacanth to the bro- 
ken pieces, which are then joined and heated in the muffle, 
but only to such a temperature that the enamel binds them 
firmly together, without completely fusing. — Pharm. Jour., 
from Pharm. Central Blatt, 1850, No. 13.
