BRONCHITIS IN CATTLE. 179 
would gain much credit, and confer an essential benefit on your 
country; for thousands of young cattle are destroyed every year 
by these worms in the air-tubes. 
Oil of tupentine is peculiarly destructive to worms. It is also 
one of those drugs that enter into the circulation ; that are re¬ 
cognizable in the urine and the breath, and produce their effect 
by immediate contact with the part on which they operate. 
Can it, through the medium of the circulation, be brought into 
contact with these worms ? It is worth the trial. Or are there 
medicines which promote expectoration, or loosen the morbidly 
viscid mucus secreted in these tubes, and cause it to be more 
easily discharged in the act of coughing? There is no doubt that 
certain drugs effect this purpose in the human being ; the exha- 
lents of the bronchi under their influence pour out an increased 
quantity of mucus, and that far less adhesive, and expelled with 
little difficulty. From the erroneous habit of contracting our 
pharmacopoeia, and shunning almost every drug in which the 
human practitioner places confidence, we have made few ex¬ 
periments for this purpose even on the horse, and none on cattle. 
The turpentine should take the precedence in this mode of treat¬ 
ment; and, that failing, it might be worth while to try the effect 
of squills or gum benzoin, or the balsams of Peru or Tolu. 
Worms in the Bronchial Passages of other Animals .—Sheep are 
far less troubled with these worms than young cattle, but several 
cases are on record in which the bronchi of these animals have 
been filled wdth the strongyli. In the deer they are oftener 
found. They are exceedingly troublesome, and often fatal in the 
hog, and they destroy thousands of poultry. In the year 1822 
almost all the pheasants in Colonel Berkeley’s preserves died; 
and on examining them the bronchial passages were choked 
with worms. Turpentine might be administered to the sheep 
and the hog;—to birds it is poisonous. 
ON THE NEGLECT OF THE MEDICAL TREATMENT OF 
CATTLE IN THE PAGES OF “THE VETERINARIAN.” 
jBj/ Mr.W. Clarke, Wymondham, near Melton, 
Although not a member of the veterinary profession, yet, 
as an agriculturist, I have always taken a great interest in every 
thing relating to it, and therefore devour with avidity the intel¬ 
lectual repast which your excellent periodical offers ; but among 
the great number of highly respectable correspondents who con¬ 
tinually enrich it with their valuable communications on the pa¬ 
thology, &c. of the horse, I am extremely surprised that there are 
none who appear to take that interest in the investigation of the
