minute portion of iron, it would not have surprised me. 
With respect to the colourless globules, resembling dia- 
mond, Professor Silliman has never treated them as carbon 
unquestionably ; and I have no evidence to offer from my 
experiments with the deflagrator. which has any tendency to 
prove that diamond globules can be produced. Iam not 
of course disposed to deny that there is much room for skep- 
ticism on this subject.

That two memoirs on fused carbon have been inserted 
in the Journal of the Academy of Natural Sciences, of 
Philadelphia, while answers to them have only appeared in 
other Journals, may excite some surprise—especially as all

Journal, Vol. Vili. p. 288,) will smile on reading the follow- 
ing report of a committee, by which it was denied publication, 
because I could not conscientiously admit that it contained

on this account, to be introduced into the Academy’s Journal, 
both in justice to the chemist, and for its own intrinsic interests. 
They would not therefore hesitate to recommend its publication.
