A New Treatment of Purpura Hemorrhagica.— 
About a year ago Prof. Dickerhoff announced a series of ex¬ 
periments with argentum colloidale crede, in the treatment of 
this disease, the results of which appeared exceedingly favor¬ 
able. This remedy, manufactured by Heyden, in Radebeul by 
Dresden, has since been tried in practice, and veterinarian P. 
Meisseur reports three interesting cases of recovery by its use. 
The first case relates to a horse which had fairly recovered from 
influenza, when on November 16 he was found suffering with 
purpura hsemorrhagica. Meissner first applied intratracheal 
injection of Rugol’s solution (iodide of potass.) with bathing 
of the swollen parts with Brown’s mixture, but the horse be¬ 
came worse, and on November 20 showed a pitiable appearance 
from great emaciation and gangrene of the skin. M. tele¬ 
graphed for the new remedy and on the next day gave an in¬ 
travenous injection of 0.5 gramm of argentum crede and 50 
gramms distilled water, repeating within two hours. On No¬ 
vember 22 he found the horse greatly improved, especially the 
swellings having diminished, and he applied a third injection. 
On the next day, two days after first injection, M. found the 
horse on the way to recovery, the swellings of the legs having 
almost entirely disappeared, the swelling of the head remaining 
latest. The haemorrhagic nasal discharge was changed to a 
clear mucous discharge, and the petecliiae had entirely disap¬ 
peared. He then turned his attention towards the treatment of 
the complications and on December 5 the horse was put to 
light use. The second case is that of a heavy Belgian horse 
which was suffering from croupous pneumonia, and on Decem¬ 
ber 3 developed purpura haemorrhagica. The sheath was so 
enormously swollen that it almost touched the ground. M. ap¬ 
plied two injections of argentum crede on that day, one injec¬ 
tion on December 4, and on December 5 he found the horse quite 
free from the more pronounced symptoms of purpura, and was 
hereafter mainly treated for a severe cough and copious nasal 
discharge, and on December 11 was considered cured. The 
third case was a Shire filly, which had been suffering from 
strangles, and on February 7 showed first symptoms of purpura
