Facts and Observations. 
STATISTICS OE DOMESTICATED ANIMALS IN FRANCE. 
The Minister of the Interior has addressed a circular 
to the prefects, directing that a general census shall be 
taken throughout the whole of France of the number of 
domesticated animals which exist in each department of the 
Empire. It is expected that this census will hereafter be 
taken in the first fortnight in December of each quinquennial 
period. 
EILARIA BRONCHIALIS OE THE CALF. 
We learn that numerous cases of Filariae in the bronchial 
tubes of calves exist in many parts of the country. An in- 
stance has just come to our knowledge in which thirteen 
well-bred calves, all belonging to the same person, died 
within a few days of each other from this cause. These 
creatures quickly multiply by the production both of living 
young and ova, a fact which is revealed by a micro- 
scopic examination. The irritation they excite in the mucous 
membranes leads to effusions which possess more or less a 
plastic character, and helps materially by its retention, within 
the bronchial tubes, to increase the difficulty of respiration 
and to produce ultimate suffocation. Terebinthinate com- 
pounds are very efficacious if early had recourse to, but in 
protracted cases they should be alternated with mineral 
tonics, of which the sulphate of iron is the best. We have 
also known the inhalation of diluted chlorine gas for two or 
three days in succession to effect the happiest result, espe- 
cially if used as an adjunct to other remedies. 
CASE OE POISONING BY YEW. 
Mr. Thomas Taylor, M.R.C.V.S. Burton-on-Trent, in- 
forms us that he was requested on August 19th to make a 
post-mortem examination of a cart-mare belonging to the 
Earl of Chesterfield, which had died very suddenly that 
morning. On opening the chest the lungs were found
