Additional evidence of Cutbush's chemical activity at this early age
may be seen in a contribution to the Philadelphia _Medical Museum_
(1808) upon mercury fulminate. This interesting body he declared to be
mercury oxalate and cited as his authority Aikin's Chemical and
Mineralogical Dictionary. He believed that its oxalic acid content was
due to the action of nitric acid upon alcohol. Such being the case, he
argued that he saw no reason why the salt could not be prepared in a
way by which "no alcohol is employed." Accordingly, he mixed
intimately two parts of salt of sorrel and one part of red
precipitate. Upon this mixture he poured sixteen parts of water, and
rubbed the solid mass intimately together. In time the red-colored
mass assumed an ash color, when it was collected on a filter and
dried. In his own words--
"On trying a part of this powder on an anvil with a hammer,
it exploded very violently, the comparison of which to that
prepared by Howard's process was nearly equal."
While Cutbush was in error, relative to the true composition of the
fulminate, he at least gave to the scientific world a characteristic
property of mercuric oxalate, which does explode with considerable
violence, while at 180 deg. C. it quickly breaks down with a mild
explosive effect. Singularly enough, he seems not to have abandoned
the view that the interaction of alcohol and nitric acid give rise to
oxalic acid.
While doing experimental work, Cutbush was active in the dissemination
of science facts through the medium of his pen. Thus it was in this
year (1808) that he published the "Useful Cabinet."
