Abstract

In my preliminary notice of this substance, I stated, upon the authority of Dr. Aitkin, that it had been supposed that it very possibly had at one time been used as a pigment in Inverness; a eolourist there manufacturing a paint the nature of which he kept secret.

In re-arranging lately, a number of chemicals which had been made over to me in 1856 by my predecessor, Mr. Connell, I found a bottle with a powder of the same tint, but somewhat darker than the washed Abriachanite. The label of this bottle bore on it "Ultramarine made in 1841, by Murdock Paterson, dyer in Inverness."

I have not yet had an opportunity of analysing this powder, which may be merely abriaehanite darkened by simple treatment with an acid.
