288 Dr. Hare’s Reply to Prof. Vanuxem. 
hak XXI.— Remarks respecting Mr. Vanuxem’s Memoir 
on a fused product, erroneously identified with the fused 
Carbon of Professor Silliman; with some additional 
Jacts and observations. By Prof. Ropert Hare. 
Proressor Silliman about two years ago, published an 
account of some phenomena observed during the iene 
of pieces of oe by a galvanic deflagrator, the poles o 
which they had been severally employed to terminate. 
On the acaba attached to the positive pole, a projection 
was observed to ensue—in the other, a corresponding con- 
cavity. The projection he supposed to consist of carbon, 
fused, volatilized and transferred from the charcoal of the 
opposite pole, where the concavity was discovered. 
Ina late number of the Journal of the Academy of 
Natural Sciences of Philadelphia, Mr. Lardner Vanuxem 
communicates his observations on a supposed specimen of 
fused charcoal sent to Professor Cooper by Dr. Macneven 
of New York, which appears to have been iron—and the 
author appears to have received, a“ é pel intends to 
convey, the impression, that the onsidered as 
fused or volatilized carbon by Professor + Silliman, must have 
been similarly constituted. 
Mr. Vanuxem, speaking of the mass which he has exam- 
ined, informs us, that— 
“Tt consisted of one large and one small globule, connec- 
ted together by a thread, or thin bar of the same materi ae 
and resembled a double headed shot.” 
breaking, and observing that it received a polish, it was eX- 
amined, and found to resembleiron. Toconfirm the analo- 
_ gy, it was next tried with a file, which acted upon it as it 
“ would. on soft steel or iron—after this it was subjected
