Argentum Crede no Substitute for Maelein.— Prof. 
Roeder, Dresden, has experimented with Argent. Crede to de¬ 
termine its value as a diagnostic agent in glanders, for which it 
had been recommended by Dr. Rerhoff. A horse which showed 
characteristic swelling of the snbmaxillary glands and one-sided 
nasal discharge was given O. S. Argent. Crede in 50.0 water, by 
intravenous injection. The temperature rose in six hours from 
39.1 C. to 41.0, remained so for twelve hours, and after twenty- 
four hours was found to be again 39.1. On the height of re¬ 
action the breathing was greatly accelerated, whereas the pulse 
remained at 44-48 throughout. The post-mortem examination 
revealed nasal glanders, the lungs being healthy. Roeder then 
applied intravenous injections of Argent. Crede in cases of 
strangles, influenza,pneumonia, pyaemia, purpura haemorrhagica, 
and to several horses in the surgical ward which were free from 
fever, in every case producing a rise of temperature of from 1-2 
degrees Celsius, the particulars being carefully noted and re¬ 
ported. Finally he injected an old, healthy anatomy-horse 
which gave reaction of 38.1 to 39.2 within four hours. Two 
days later this horse received 0.5 mallein without reaction and 
on being killed for dissection was found to be healthy. The 
results go to show that so far no chemical agent has been found 
which can be looked upon as a substitute for mallein, which up¬ 
holds its claim as a biological product on a scientific basis.—

ENGLISH REVIEW. 
Laparotomy [By IV. Panier]. — Antisepsy has certainly 
opened the doors for interference in abdominal cases, where 
before it, the surgeon would hesitate and often refuse to act,— 
and while peritonitis would not often follow abdominal surgical 
manipulations in dogs, to-day, thanks to antisepsy, these can be 
almost considered as never fatal. The author reports the case 
of an Airedale dog which was brought to him suffering with
