eration in'cases demanding surgical interference within the 
pharynx, or far back in the month where the soft palate is in 
the operator’s way. 
The value of voluminous intratracheal injections in wash¬ 
ing out the bronchi was very evident, the muco-purulent dis¬ 
charge from the trachea ceasing very promptly and remaining 
in abeyance until shortly prior to the destruction of the animal,, 
when new causes arose to bring about a recurrence of the 
malady. 
The danger from tracheotomy in the presence of suppura¬ 
tive bronchitis is strongly emphasized, for while the operation 
and handling of the wound were accompanied by the usual pre- 
cautions against serious infection they were evidently insuffi¬ 
cient and the ineffectiveness of these ultimately led indirectly 
to the death of the patient. 
An autopsy could not be had, and efforts to recover the sil¬ 
ver tube failed, but judging from other data coming into our 
possession after the operation and death, a serious error was 
made in the material composing our trachea tube because of its 
destructability in contact with the tissues, and the consequent 
irritation to the parts inducing suppuration and ulceration of 
the contiguous parts, while the discharges therefrom entering 
the bronchi aroused anew the previous muco-purulent bron¬ 
chitis and nasal discharge. The silver used in making the tube 
was represented to us as 925-1000 pure.' A somewhat similar 
tube of the same degree of purity, fixed in the trechea of a 
horse by us and kept in position for 28 months was found on 
removal to be greatly eroded, roughened, at some points com¬ 
pletely destroyed, losing on the whole approximately Y / 2 its 
weight. Whether this was due directly to the destruction of 
the metal or indirectly to the solution of the alloy in the metal 
has not been determined. Apparently all constituents of the 
metal have suffered alike. The tube at least shows that silver 
apparatus 925-1000 fine is not suitable for permanent fixation in 
the air passages of the horse, as it will gradually erode and 
irritate the contiguous parts.
