rounding vegetation in the form of a grayish-blue powder, an 
when these plants are eaten by horses, they may give rise t 
symptoms of poisoning. According to the author, the action c 
the lead does not cause symptoms similar to those in man, such a 
colics, but he holds that the poison acts upon the larynget 
nerves. While at rest the animal does not seem to be sick; bt| 
if put in motion, there is a slight whistling and dyspnoea, whic 
manifest themselves and continue for some time after the anira* 
has ceased to exercise; but, after ten minutes, all pass away, an 
do not again appear unless the animal is again moved. Thes 
symptoms are also observed during mastication, and especiall 
when eating hay. They vary in intensity according to the quar 
tity of lead absorbed; but the difficulty of breathing is alway 
present, and is so characteristic that there is no difficulty in diao 
nosticating saturnine intoxication from ordinary roaring. Th 
chemical analysis of the organs of these animals—such as th 
kidneys, liver, spleen, stomach, and intestinal walls—reveals th* 
presence of the lead. No treatment seems to be of any benefit 
even at the outset. Tracheotomy appears to be the only mean 
of continuing the usefulness of the horses for any great length o 
time.— Rundschau. 
CONTRIBUTION TO THE TREATMENT OF IMMOBILITY. 
By M. Klemm. 
After using the sulphate of eserine in sub-cutaneous injec 
tions, in doses of from ten to twenty centigrammes, withou 
obtaining any satisfactory results in the treatment of immobility 
the author had recourse to the hydrochlorate of pilocarpine, ir 
doses of one gramme in medium-sized animals, and one grannnt 
and twenty centigrammes in larger ones. The sialagogue anc 
sudorific action of this substance seemed to modify the cerebra 
circulation for a lasting period. The author claims to hav< 
obtained radical cures by this treatment. His numerous experi 
ments and observations have brought him to the following con 
elusions : 
1st. At the outset of the disease, the treatment with pilo 
carpine is followed nearly always by radical cure, and the cer
