Some months ago, the researches of WINKLER and VAN RiuNBERK 
were published, *) a series of experiments in which, by means of 
the SHERRINGTON isolation method they demonstrated on a large material, 
comprising 40 objects, the dermatomery of the hindleg in dogs. 
When that work was published, the series of my experiments was 
nearly completed and I could state an indeed striking accordance 
between the results obtained by those investigators as to shape, 
situation and extension of the dermatomata they found, and my 
strychnine segmental zones defined by means of this strychnine method, 
an accordance and a resemblance that in some cases grew nearly 
to identity, as will be shown here after. 
I intend in the following pages to give the results obtained by me 
in that respect, comparing everywhere my strychnine segmental zones 
with the proportions found by Winkier and van RIJNBERK for their 
dermatomata. 
The theoretical speculations and consequences resulting from the 
facts that will be told, shall not find any place in this communication. 
Th. XII. The strychnine zone of this segment, like those of the 
trunk segments, presents still a very simple shape, its various properties 
therefore are clearly enough demonstrated by the Fig. V and VI 
without adding anything.
