recognized it to be similar in its nature and appearance, to a 
product of the iron furnaces of Belgium, which has been 
described by Mr. Bouesnal in the “Journal des rezweh 
(Vol. 29. p. 35,) under the name of Cadmia. Having had 
an opportunity of collecting on the spot* the most satisfac- 
tory proofs in support of my opinion, I beg leave to offer to 
the Academy the following account of this substance: It 
was first noticed at Ancram in the year 1812, when it was 
found in pulling down a stone wall connected with the iron 
urnace, which belongs to general Livingston, and is now 
under the direction of Walter Patterson, “Esq. It excited 
some interest among the mineralogists of New-York, but 
no public notice was taken of it until lately. Mr. Boues: 
nel’s observations on this subject are very full; these and a 
few short notes by Messrs. Collet De scotils, Heron de 
Villefosse and Berthier in the “Journal and Annales des 
Mines,” are the only notices of it I have ever met with; 1 
sought in vain for a mention of it in English works. The 
cadmia of Belgium is a new and rare metallurgical product, 
which is formed in iron furnaces about five or six feet below 
their orifice, and immediately under the charge; it there 
forms an annular disk or ring, which increases ne in 
thickness, and which, if not removed, would choke 
furnace ; it forms in the Belgian furnaces, according to un 
Bouesnel, a ring of about sixteen inches in height, offering 
in the profile or vertical section, a curvilineal triangle, a 
base of which rests upon the sides of the furnace; and 
apex which corresponds with its greatest breadth, is but lit 
tle distant from the lower part of the ring, so that the trian- 
gle appears in some cases almost rectangular.” T have seen 
a piece found at Ancram, which presented tolerably well 
the above described characters, and corresponded exacily 
with Mr. Bouesnel’s description; hke the European, it 
was found in tabular masses, presenting in many cases a 
distinct slaty structure. The substance has often a striped 
aspect; its color is grayish, inclining to yellow, green or 
black. The specific gravity of the European is 5. ae 
the American 4.92; this difference is not very great, and 
may in part be accounted for, by the fact that the foptier
