Papers relating to the H'usion of Carbon. 109 
In the experiment detailed in Vol. V. p. 363, of the same 
Journal, the carbonic acid found, probably had a similar 
origin, and the disappearance of the globules may have been 
owing to their incorporating themselves with the piece of 
brick upon which they were placed, as the brick was vitrified 
at the point where they were placed. 
Professor Silliman seems disposed to lay great stress on 
the loss in my examination, of the globule, sent by Dr. Mac- 
neven. I thought I had well accounted for it, as the particle | 
how 
moment entertain the idea that carbon existed in it, in any 
notable proportion ; for I know of no combination of iron and 
carbon at common temperature, which could give a product

I was sorry. to observe that Se Silliman in his reply 
to my paper, seems offended that I did not notice his com- 
munications upon the subject of ri globules, particularly 
as the discovery was his, and was justly entitled to such con- 
sideration. My silence certainly * uncourtly, but it 
was not owing to ignorance of his labours, or a want 
regard to him personally, or as a chemist ; Professor Silli- 
man’s merit is too well known to be affected by me

in the spring of 1823 Professor Silliman paniahet in this

courteous, especially when, not possessing the means of obtaining f fused 
carbon, he omitted to apply for it to the person most inte: gag who
