Dr. Ruston. I believe I have.
Couns. for the Pris. What is the form of these medicines?
Dr. Ruston. Powders, pills, and drops.
Couns. for the Prisoner. What are the ingredients which compose the powder?
Dr. Ruston. I verily believe the powder to consist entirely of calomel and æthiops mineral.
Couns. for the Pris. What are your reasons for thinking so?
Dr. Ruston. My reasons are founded on chemical experiment and analogy.
Couns. for the Prisoner. What experiment and what analogy?
Dr. Ruston. 1st. To a small quantity of Mr. Sutton’s powder, which was of a greyish colour, I added a few drops of volatile alkali, which immediately changed it to a deep black. 2dly. To a small quantity of the same, a few drops of a solution of salt of tartar were added, which produced the same colour. 3dly. A few drops of lime-water were added, which also changed the powder black, but not quite so black as in experiment 1 and 2. The colour and weight of Mr. Sutton’s powder were exactly imitated by the addition of six grains of æthiops to ten grains of calomel, and by repeating the above experiments with this composition, it was found to exhibit exactly the same phenomena.
Couns. for the Prisoner. Now, Sir, as to the pills?
