cts were laid bare. Frequent favorable mention was made by Cutbush
of John Redman Coxe, hence probably the appearance of several of his
contributions in the pages of the Philadelphia _Medical Museum_,
edited at this particular time by Coxe. For example, in 1809, Cutbush
published an article on the formation of ether in this journal, and
suggested that the product of the interaction of sulphuric acid and
alcohol could be best purified by distilling it over manganese or lead
dioxide and not over caustic potash as was customary. He also dwelt on
the production of ethylene in this process, attributing its presence
to the dehydrating action of sulphuric acid upon the alcohol.
Momentarily, he rejoiced over this observation, believing it was new,
but promptly subsided when he discovered that Fourcroy and Vauquelin
had long before made the same observations and given the same
explanation. Two years later (1811), in the same journal, Cutbush
reported results gathered from experiments to determine the value of
the hop to brewers. He said much in regard to its essential oil in the
preparation of malt liquor and repeated earlier personal observations
upon the importance of chemistry in the brewing operations--

"An art in which, to the principles of chemistry, many
improvements have been made. To our worthy and ingenious
countryman, Mr. Hare, much praise is due for various
improvements in this art, which, we may add, were in
consequence of his correct principles in chemistry and
natural philosophy."

Here is one of the few references to Robert Hare made by Cutbush. It
was when Hare was devoting most of his time and mental energies to the
development and improvement of his father's business. He applied his
scientific knowledge to it, only in the end to have it fail through
the conditions which came upon the country during the period of the
War of 1812. One cannot easily forget the filial devotion of Robert
Hare to his father in this particular business. Gladly would he have
pursued pure science, but he knew his duty and assumed it, although
unable to devote much time to science until 1818. But that story has
been told. Another appreciation from Cutbush which appears years later
reads as follows:

"The deflagrator of Professor Hare of Philadelphia is an
apparatus well calculated for many interesting experiments
on galvanism. To that gentleman we are indebted for the
compound blowpipe, which
