ANIMAL VACCINATION. 
the animals. In this case, however, they give rise to an 
unarmed Taenia, whilst t^ie same worm, if swallowed by a 
carnivorous or omnivorous animal, would become in its in¬ 
testines an armed Taenia, that is, provided with the hooks of 
the scolex from which it originates, and which in the former 
cases it loses. 
Some unarmed and armed Taeniae are therefore two adult 
and parallel forms of the same worm, and the differences, 
often very great, which they present (as in the Tcenia per - 
foliata of the horse and the T. echinococcus or T. nana of the 
dog which originate from the same worm), are due ex¬ 
clusively to the difference of the habitations in which their 
final metamorphoses are accomplished.— Journ. Hoy. Mic.

ANIMAL VACCINATION. 
Dr. Cameron has introduced a Bill into the House of 
Commons with a view of obviating the objection which 
some people have to vaccination, on the ground that, if the 
lymph has been obtained from an unhealthy child, some 
maladies may unintentionally be communicated along with 
the cow-pock. The Bill imposes on public vaccinators the 
duty of vaccinating a child with animal lymph whenever its 
parent or the person having charge of it requires them to do 
so. The Local Government Board is directed to take 
such measures as may from time to time be necessary to 
secure for the public use a supply of animal lymph, and to 
provide for its distribution to public vaccinators and medical 
practitioners, the cost of such measures being defrayed out 
of moneys provided by Parliament. A maximum penalty 
of three months’ imprisonment, or of a fifty pound fine, is 
imposed on those who knowingly supply or use as an animal 
lymph for vaccination anything that is not so. fc Animal 
lymph ” is defined as being vaccine lymph, either fresh or 
preserved, obtained directly from cow-pock vesicles upon a 
calf or heifer, and derived by propagation through a series 
of calves or heifers from virus obtained from a case of natural 
cow-pock. The Bill has been withdrawn from lack of time, but 
the subject will require to be dealt with .—Sanitary Record.
