The Action of Iron in the Formation of Brood [Dr. 
A. Hojfmanri\ .—In animals to which iron preparations were fed, 
the author could detect an enormous exuberancy of cells in the 
marrow of the bones, up to its most peripheral parts, which 
plainly proves that the marrow of the bone has to be considered 
as a blood-regenerator. The irritation effected by the iron pro¬ 
duces a quicker transformation of the marrow cells into red 
blood corpuscles and a similar compensation of marrow cells 
through new production. The spleen and liver of animals fed 
with iron do not show any marked changes.—( Virch. Arch.) 
Treatment of Punctured Wound of the Foot with 
Pure Lactic Acid [Guillemain and Cadix~\. —The hoof is 
properly cleansed with a sublimate solution, and the horn sur¬ 
rounding the wound is removed. The lactic acid is then poured 
on the wound. After a few moments place a small tent of oak¬ 
um which is previously sterilized in boiling water, and which is 
saturated with lactic acid, as deeply as possible into the wound. 
In cases of severe lameness, the application of a cataplasm of 
flaxseed meal, and a strong antiseptic solution is advisable. 
The following day the tent of oakum, which will be dry, is 
removed and the wound moistened again with lactic acid. In 
very severe cases the use of the oakum tent and the poultice is 
continued. Generally after the first two days’ treatment the 
animal is considerably relieved, but in case there is no improve¬ 
ment on the third day, the same treatment should be continued. 
The authors claim that they have employed this treatment ex¬ 
clusively for a year, in more than 15 cases, with continual good 
results. On an average the animals were not laid up more than 
seven days.— [Recueil de Med. Vet .] 
The Treatment of Parapuegic FLemogeobinuria in 
the Horse. —The author considers four forms of this disease : 
(1) Mild cases ; (2) paralysis of one of the nerves ; (3) apoplec¬ 
tic form ; (4) paraplegic form. (1) The mild cases are charac¬ 
terized by profuse perspiration, staggering gait, and dark 
urine. Bleeding and friction with straw will soon bring about 
a cure. (2) Paralysis of one of the crural nerves. This form 
manifests itself by very difficult gait; excessive bending of the 
extremities, and dark urine containing haemoglobin ; in the 
first hours the patient is covered with perspiration. Bleeding 
in these cases is of doubtful value, applications of ice cold 
blankets to the loins, after perspiration ceases. In the case
