antidotes, such as sulphate of copper and permanganate of potash. 
In such desperate, but by no means rare cases, the only antidote 
which comes under consideration is the so-called ozonised oil of 
turpentine, which forms with the phosphorus the so-called turpentine- 
phosphorous acids studied by myself jointly with my pupil O. Busch^). 
We found that these acids are less toxic than phosphorus. As 
such a careful investigator as Stich^) had completely denied the 
existence of these acids, I determined to have Stich's statement, 
that these acids be only a mixture of phosphorus with oil of tur- 
pentine, submitted to a test. This task has just been completed by 
my pupil August Fischer^). The result obtained by him shows 
that the so-called turpentine - phosphorous acid is not a mixture of 
phosphorus and oil of turpentine (as Stich maintains), but on the 
contrary that, as Busch had already assumed, it represents a mixture 
of several compounds of phosphorus (differing in their phosphorus- 
content), with oil of turpentine. This admitted, the treatment of acute 
cases of phosphorus poisoning with ozonised oil of turpentine remains 
fully justified. I propose to study the action of turpentine-phosphorous 
acids on animals once more with my pupil R. Glette. 
13. Group of Dermerethistics, 
There is no reason to assume that the application of remedies 
provoking irritation of the skin is out of date, because they have 
been borrowed from popular medicine, and are looked at askance by 
some theorists. On the contrary, in practice we very frequently use 
the aethereo'oleosa belonging to this class, and obtain excellent results 
in the following indications. 
In order to produce in cold feet the pleasant feeling of warmth, 
and to stimulate the circulation in them, mustard-baths and rubbing 
with spirit of juniper and especially spirit of mustard, are useful. 
After the mustard -bath the feet, which have become red as a lobster, 
are given a douche of cold water, rubbed slightly, and then put into 
clean dry stockings and shoes ; this produces an exceptionally pleasant 
feeling which continues for a long time. An examination of the toxic effect 
of oil of mustard was made at one time by myself and R. Heinz 
When the skin is badly nourished, atropic, dull, and pale, as occurs 
so often in scrophulous and rhachitic children in addition to a high
