deenshire. Professor Liautard, with whom we frequently con- 
ferred during the autumn, did not attempt to give any name to 
the disease. The same was true of Professor James Law, the 
accomplished professor of veterinary science at the Cornell Uni- 
versity, Ithaca, N. Y., whose attendance we had the good for- 
tune to secure at one of the last post-mortem examinations made 
at the National drove yards, One Hundreth street. The latter 
eentleman has, with characteristic thoughtfulness, kindly forwarded 
to us the subjoined communication relating to the points we are 
here examining: 
The „darn“ as seen by us in Great Britain (Professor Law 
is a native of Scotland) is usually a very mild affection. Its cause 
is agreed on all hands to be the ingestion of irritant, resinous 
and adstringent plants, as its common names — in England, 
wood-evil; in Germany: Holzkrankheit, and in France: Maladie 
de bois — would indicate. The symptoms are those of intestinal ir- 
ritation, the colicky pains being often severe, with constipation ; 
the faeces, if passed, being coated with mucus or even blood, and 
in bad cases forming a tarry mass evidently due to altered and 
effused blood. The urine, red or black, contains large quantities 
of blood-colormg matter and albumen. 
If seen in the early stages, measures directed to the obtaining 
of free evacuations from the bowels are almost always followed 
by a speedy restoration to health, so that I have never seen a fatal 
case. 
It is worthy of note, that it often prevails on the same lands 
with the anthrax or carbuncular affections, and appears then to 
be complicated by this disease, or modified by a similar cause. 
Röll, of Vienna, says there will sometimes appear „a gelatinous ex- 
sudation into the sub-cutaneous areolar tissue, and extravasation 
beneath the serous membranes, showing a complication with an- 
thrax. The malady begins with the appearance of gastro-enteritis, 
accompanied by renal irritation, scanty, red or bloody urine, great 
sensibility of the loins and intense fever, mucous and bloody 
faeces, foetid and bitter milk, with not unfrequently spasms or 
convulsions. The complication with splenic apoplexy (Milzbrand) 
is seen, and may be shown by swelling and emphysema of the sur- 
face of the body.“ 
Hering and others speak in analogous terms, indicating its 
close connection with the anthrax affections, though whether only
