a belief in it; nevertheless, we do hope that our experiments may 
contribute, in some degree, to the elucidation of this great pro¬

we should not hesitate to reply, No ! !

ON BRONCHITIS IN CATTLE. 
Bi/ Mr. Meyer, Sen.y F.-S., ISewcastle-under-Line. 
Messieurs Editeurs, 
As many of your contributors will, no doubt, feel interested in 
having the ultimate results attendant upon the treatment of those 
cases of bronchitis noticed in a former number of your journal 
(vol. vii, p. 585), I have much pleasure in forwarding the par¬ 
ticulars without further preface, except that I would apologize to 
Mr. Youatt for not having noticed, in my last paper, his article 
upon bronchitis in that valuable publication. The Farmer's Series ; 
it did not meet my eye till some time afterwards: had I seen it, 
it would have superseded much that mine contained. Having 
thus made the amende honorable^ I shall proceed :— 
The little patient, upon which the operation of tracheotomy 
had been performed, recovered much of its condition, spirits, and 
appetite; but as the wound in the trachea gradually healed up, 
it pined away again, and ultimately sunk, although the Indian 
pink, conjoined 'with saline medicines and fumigations, were 
followed up to the last. On a post-mortem examination, I found 
not more than half the quantity of worms as in the first case, 
many of them having, no doubt, been expelled or crept out 
through the opening into the trachea. The anterior and middle 
portions of the lungs were of a bright vermilion hue, shading 
gradually off to their natural colour towards their posterior por¬ 
tion. The lining membrane of the bronchi and air-cells was 
much inflamed, but not so that of the trachea. 
I consider the operation of tracheotomy, in extreme cases, as a 
most valuable aid; but it should be done low down, as it af¬ 
fords, in the first place, greater facility for the expulsion of 
worms ; secondly, by admitting currents of cold air immediately 
upon their nidus, it renders their habitation less tenable. 
Thirdly, it allows you, as the wound closes up, the opportunity 
of operating again above. The operation is of the highest im¬ 
portance too in taking off the spasmodic effect produced upon 
the laryngeal muscles from the sympathetic irritation and effects 
of the worms, occasioning asphyxia to a great degree, but which
