Analysis by W. H. Ellet, M. D. I have examined a sub- 
stance labelled "Acetate of Morphine," furnished me for that 
purpose. It was in the form of a powder of unequal fineness, 
but with no appearance of crystalline structure. It had a 
slighlty yellowish colour, an acid taste, and an odour resem- 
bling that of sulphuric acid, which has been contaminated 
with small quantities of vegetable matter. It was very 
slightly soluble in water, which liquid however, even in 
small quantities deprived it of its taste, and became itself 
acidulous. The acid matter contained in the solution was 
found on examination to be free sulphuric acid. The undis- 
solved portion proved to be sulphate of lime. No indications 
were obtained, from experiments made for the purpose, of 
the presence of morphia, or any other of the vegeto-alkalies. 
As nearly as I was enabled to determine from the small 
quantity of the article furnished me, it consists of sulphate of 
lime, mixed with from seven to eight per cent* of impure sul- 
phuric acid.

Analysis by J. J. Tobin M. D* and S. Rosengarten. Having 
been requested by Messrs. Rushton and Aspinwall to analyze 
a powder which they had received as acetate of morphine, 
We herewith inform you of the result of our chemical investi- 
gation, and the method we employed in order to determine 
with accuracy the composition of the said powder* in as far 
as it was in our power so to do, in the short space of time 
which those gentlemen could allow us, and our other occu- 
pations would permit.
