As absorption of the
particular drug employed is not necessary, and therefore not to be
desired, Dr. Mackenzie now uses creosote only, either pure or dissolved
in one to three parts of rectified spirits. "Whether," says he, "the
success so far attained is due to the antidotal action of creosote and
carbolic acid on a specific tubercular neoplasm, or to their action as
preventives of septic poisoning from the local center in the lungs,
it is certain that their continuous, steady use in the manner just
described has a decidedly curative action in acute phthisis, and is
therefore, worthy of an extended trial."

ON THE LAW OF AVOGADRO AND AMPERE.
The Scientific American Supplement of May 14,1881, contains, under this
head, Mr. Wm. H. Greene's objections to my demonstration (in No. 270
of the same paper) of the error of Avogadro's hypothesis. The most
important part of my argument is based on the evidence afforded by the
compound cyanogen; and Mr. Greene, directing his attention to this
subject in the first place, states that because cyanogen combines
with hydrogen or with chlorine, without diminution of volumes, I have
concluded that the hypothesis falls to the ground. This statement has
impressed me with the conviction that Mr. Greene has failed to perceive
the difficulty which is at the bottom of the question, and I will,
therefore, present the subject more fully and comprehensively.
