378 VETERINARY SURGICAL THERAPEUTICS. 
For a long time, it was believed that adenitis were primitive, but it is ad- 
mitted to-day that the glandular inflammation results, in all cases, from 
an inoculation produced either directly through a wound of the gland, or 
indirectly by a lesion some distance from it, existing on the course of the 
afferent blood-vessels. Glands seem even more sensitive than the vessels ; 
in clinics, lymphangitis without adenitis are exceptional; adenitis with- 
out lymphangitis are not. 
If the most varied micro-organisms circulating in lymph may irritate the 
glandular sifter, acute adenitis, like lymphangitis, are ordinarily produced 
in animals by staphylococci and sometimes by streptococcus. The re- 
searches of Schwarznecker and ours show that ordinary adenitis of horses 
are generally due to the staphylococcus albus. The clinical varieties of 
adenitis (tumefaction, induration, suppuration) are related to the varying 
virulence of this staphylococcus. It is the streptococcus of Schiitz which 
causes the suppurating adenitis of distemper. In bovines and other 
animals, acute adenitis of various nature have also been observed, most of 
them due to ordinary pyogenous microbes. 
Ordinarily produced by inoculation from a wound at some distance from 
it, adenitis demands first the use of antiseptics on the wound and the 
afferent lymphatic blood-vessels, completed by a wadded dressing. The 
primitive lesion, cutaneous or mucous, should be treated by antiseptic 
irrigations, pulverizations or baths frequently repeated. Hot balneation 
is to be preferred. Upon the inflamed gland, tincture of iodine may 
be applied, a blister, or better, when possible, tepid antiseptic com- 
presses. Intra-glandular injections of phenicated water 3 p. 100 
(Hueter) have not been tried in animals. General and local bleeding are 
abandoned. 
The march of the inflammation depends on the degree of virulence of 
the germs. A well made antisepsy will get the best of a microbe with 
weak virulence ; little by little, the swelling diminishes, the pain subsides, 
resolution takes place. Other germs, more active, produce pus. As soon as 
it is formed, it must be allowed to escape and then antiseptic washes used. 
The opening of some glandular centers—subparotid or retro- pharyngeal 
abscesses, those of the axilla or of the groin—demands some attention ; in 
these regions, the bistouri must be handled with prudence, if large vessels: 
and nerves-are to be avoided. The free incision of the maxillary glands is 
without danger, and the puncture occupying dependent location, pus always 
runs freely. At times, specially under the parotid, the pus has reached 
the periadenic cellular tissue, there are great underminings and the 
glandular origin of the abscess is difficult to locate. In such cases the 
incision must be made large ora counter opening established ; drainage is 
also obligatory. Ordinarily the wound closes rapidly. If healing goes on
