1881 Excerpt: ...some degree a continuous retort, but to a greater
degree belonged to the class of intermittent ones. Henderson
cleverly modified this, dispensing with the delicate arrangement of
the air lute, and substituting a neat simple door on the bottom, by
which he dropped the hot shale into a fire below, and converted it
into a purely intermittent retort. Unquestionably Henderson's was
the best intermittent retort in uso at present. Many other plans
had been tried, such as causing the simplo combustion of the shale
to distil itself, to distil by hot gas alone, Mr. Kirk. by hot
steam alone, and revolving retorts, which he had seen at work in
North Wales, but none of these had been established in settled
practice. Now, to come to the Author's comparison of Henderson's
retort with a vertical retort, or what he termed the " old retort";
here unfortunately there were many and serious misstatements of
facts. Mr. Henderson's retorts were not " originally adopted by the
Broxburn Oil Company." They were originally adopted by the Oakburn
Oil Company, and it was while in their employment, after they had
worked both of Mr. W. Young's retorts, as described above, under
Mr. Henderson's more immediate superintendence, that they, when Mr.
Henderson proposed his improvements, adopted them so far as their
extensions required. That was in 1874-5, and for the two following
years Mr. Henderson remained in their employment, working his
retorts along with Young's and the old retort. When after that he
went to the service of the Broxburn Company, he naturally was able
to introduce further improvements, the result of experience. The
Author's comparison of the products from the rectification of 100
gallons of crude oil, as made by Henderson's and by the old retort,
