and in conducting experiments. Very recently a calf and 
Iamb had administered to them several segments of those 
varieties of the tape-worm, well filled with matured ova, on which 
the so-called "measle," or rather "mizzle," of beef and mutton are 
believed to depend. The " measle " is in reality an embryotic 
tape-worm, or a tape-worm in its larval or hydatid stage of 
development from the ova, which, on entering the digestive 
organs of man, in its living condition in beef or mutton, quickly 
matures into the perfect entozoon, often many feet in length. 
A period of three months at least is necessary for the develop- 
ment of hydatid embryos from the ova ; and should success in 
these cases attend the exhibition of the ova, it may be hoped 
that the experiments will be sufficiently complete to be communi- 
cated to the Society in the next quarterly Report. 
It will be in the remembrance of the Society that a year since 
an inquiry into the ravages committed by the Strongylus hron- 
chialis was undertaken at the request of the Lincolnshire Agri- 
cultural Society — that county having often suffered severe losses 
by the death of lambs from attacks of the parasite. A series of 
questions has been circulated by the Society among its members 
and others, and the answers already received have been arranged, 
but no correct conclusions can be arrived at until certain experi- 
ments now being conducted are completed. These experiments 
have for their immediate object the further elucidation of the 
natural history of the entozoon, more especially during the period 
of its existence extern to the bodies of its victims. 
Referring again to the lung-worm of the calf, it may be 
stated that the parasite gives rise to the disease commonly known 
by farmers as the " hoose or husk," from the peculiarity of the 
cough of the affected animal. The malady is accompanied with 
great emaciation of the animal, so that death not unfrequcntly 
results from inanition and persistent irritation, as well as from the 
structural changes which take place in the lungs. The cure lies 
chiefly in the early destruction of the worms, and for this purpose 
medicated inhalations are of essential service. These are best 
applied by burning tar in a shed in which the calves are tem- 
porarily confined, and casting sulphur on the flame from time to 
time, care being taken that there is a sufficiently free access of 
air to prevent suffocation. 
The exhibition of oil of turpentine, tincture of assafcetida, 
decoction of savin, and other allied agents, will also effect much 
<rood. To these remedies should succeed tonics both mineral and 
vegetable, of which the preparations of iron and the barks are 
the best.
