TRICHINIASIS IN SWITZERLAND. 
M. ZuNDEL, of Mulhouse, writes that trichinae have made 
their appearance in the canton of Ticino, at Ravecchia, near 
Bellinzona, and that several persons had suffered from trichi- 
niasis, five of whom had died. Professor Zangger, of the 
Veterinary School, Zurich, had instituted an inquiry on the 
spot, and discovered trichinae in some pork obtained from a 
ready-cooked pork-shop."’^ 
It is not known by what means the entozoa were imported 
into Switzerland; but the researches of Professor Metzdorf 
have shown the presence of trichinae in rats killed at the 
common slaughter-house in Zurich. M. Ziindel adds that 
similar researches made at Mulhouse have not shown either 
the flesh of pigs or rats to be affected with trichinae. 
CRUSTA LACTEA IN LAMBS. 
Our attention has been called to some interesting cases of 
skin disease which have shown themselves in several parts of 
the country among the lambs. The disease has most of the 
characters of so-called Crusta Lactea of the human infant; 
indeed, it appears to be identical with it in its pathology. 
The parts affected are chiefly the face, eyelids, and ears; on 
the latter especially the crusts are thick, and of a dark colour. 
In some lambs the eyes suffer considerably, and a glutinous 
discharge comes from the conjunctiva, which glues together 
the lids. In a few cases the disease extends down the neck 
of the animal, after having existed for a few weeks; but in the 
majority it is confined to the head and faee. It is accompanied 
with mueh irritation, and the young animal frequently breaks 
the crusts, and causes slight haemorrhage from the surface, 
by scratching and rubbing the parts. Death has followed m 
a few instances from irritative fever. The attack generally 
comes on when the lamb is about three weeks old, but only 
about half a dozen cases are usually found in a flock of 150 
to 200. The disease does not yield readily to treatment. 
We have found it necessary to bring the lambs with their 
dams into the sheds, so as to protect them from the sun, and 
also inclement weather. Good nursing is required, and also 
careful dressing and cleansing of the affected parts. The 
application of the oxide-of-zinc ointment has proved bene-
