(2.) In the two dogs, especially in the first, remarkable collections 
of leucocytes were seen in the adventitia of the smaller and medium 
sized vessels, in all the sections. Here and there the inner coats of the 
vessels would not be seen for the accumulations of corpuscles. This 
condition was well marked in the oblongata, and in the motor centre 
of the trigeminus. In several localities small hemorrhages were de¬ 
termined. No trace of abscesses of pigment flakes. 
(3.) The section of the horses’ brain showed a perfectly normal 
structure, T he blood vessels were almost completely empty, and pre¬ 
sented only a few rather doubtful traces of increase of the leucocytes in 
the adventitia. 
(4.) In the ox nothing abnormal was fouud. 
In normal brains of the dog and man treated by similar methods, 
no trace of these collections of leucocytes were found about the vessels, 
which establishes the pathological significance of this condition of hy- 
diophobia, though it was not constant, and never so marked as in cases 
of piogressive brain palsy. The small hemorrhages result from dis- 
tUibances in ihe circulation during the paroxysms, and the same are 
met with after epileptic attacks. I hese changes occur so frequently in 
many acute and chronic affections—progressive paralysis, typhus, epi¬ 
lepsy that they cannot be regarded as in any way pathognomonic of hy¬ 
drophobia .—Deutsche Zeitschrift fiLr Thierinedicin . Bd. II /, Hft. IV. 
THE TRICHINA EPIDEMICS OF SAXONY. 
During sixteen years from 1860 to 1875—39 trichina epidemics 
weie observed in Saxony. The total number of cases, exclusive of light 
ones, which were not reported, was 1,267, and of these 19 died—1.58 
per cent. 
In relatively few cases was the infection produced by eating raw 
flesh ; by far the larger number of the cases were due to the ingration 
of smoked or fried sausages, 630 of the former, and about 340 of the 
latter. These sausages were made of chopped flesh, smoked for a few 
days, and then eaten cold, or fried for a few minutes. Among other 
sources oi infection were brain sausages, thick sausages and ham. Of 
the 19 fatal cases, 3 had eaten raw flesh, 2 smoked, 8 fried sausages, and 
2 ham. The source of infection in the other four cases was not ascer¬ 
tained. Of these cases, 15 were women, and only 4 men. The epi¬ 
demics appeared in 22 localities ; in Dresden, occurring seven times \ 
m Leipzig, twice. In only one place did two epidemics break out with-
