Roup or avian diphtheria may attack all varieties
of the domesticated fowls, also cage and wild birds. The
characteristic symptom is the appearance upon the lin-
ing membranes of the mouth and nose of peculiar yel-
lowish patches which resemble those present in the
throats of children suffering from diphtheria. These
patches are adherent to the parts upon which they rest,
and when stripped off, cause a raw bleeding surface. In a
few days they become yellow, much thickened, and inter-
fere with the breathing and prehension of food. In some
cases the eye is affected. The eye-lids become glued to-

gether, nlild the mniiterinl collects upon the front of the
eyelbll causing great bulging and final destruction of tlhe
eye. A peculiar nauseating odor nccompanies the disease,
(hue to the decomposition of the pent-up secretions. Ema-l
citation is rapid, from the absorption of poisons formed
by the disease process, and from the inability to eat. In
some outbreaksl the disease attacks the intestines, result-
ing in bloody discharges aind great loss. It lasts from a
few days to a few weeks according to its being acute or
chroimic in character. Some claim that group is the
same as diphtheria in iiimi. If they are the samin disease
why canl we not findl the germ of diphtheria in roupy chick-
ens as certainly as we can in a case of true dilphtheria in
man? Moreover, why can we not 'apply the diphtheria
antitoxin treatnmnt to fowls with the same expectation
of favorable result as is now oht:ined by its use ii hlu-
man diphtheria.
I am unaware that anyone has yet satisfactorily
demonstrated that the initial lesions of roup are due to a
germ. Undoubtedly the putrefactive germs which are
found in the sores have much to do with, the progress of
the disease. Roup is often confounded with other affec-
tions, the most common ones being ordinary colds and
infectious catarrh. In any disease of this nature which
has lasted three or four days, and in which the formation
of yellowish patches upon the tongue, roof or back pairt
of the mouth has occurred, treat for group. If the fowl is
worth treatment, destroy it and burn the carcass.
The indications for treatment are isolation of the af-
fected ones, a completee renovation of the hen house by
scraping the floors, burning old nests, a liberal coat of
whitewash to all wood work, and coating the floors with

I layer of lime. This is to be followed Iy medicinal
treatment of the affected ones. This should, in part, con-
sist of the use of antiseptic washes for the nostrils, mouth
and throat.- Any of the following washes may be used:
a 2% solution of creolin applied to the parts with a
brush; equal parts of kerosene and olive oil, or cotton
seed oil; boric acid, 15 grains to the ounce of water. In
app)lyi1ng any one of these solutions, first remove those
portions of the patches which can be detached without
causing I)blod( to flow. It is considered good practice to
also dust the cleansed surfaces with (lowers of sulphur.
The following wash is recommended by Salmon:
Dissolve thirty-five grains of chlorate of potassium and
two grains of salicylic acid in one ounce of water, and
add one ounce of glycerine. Apply this liquid to the
spots two or three times a day, and give a teaspoonful of
the mixture internally to each fowl. Great relief is af-
forded the fowls by fumigation. Place the fowls in' a
tight building and pour oil of tar on a hot brick, piece of
iron or a shovel. Do this twice daily.
The tumors which form on the head should be opened
with a sharp knife, and their contents washed out. The
bleeding which frequently occurs camn be checked by fill-
ing the cavity with raw cotton saturated with chloride of
iron. Zurn recommends internally and externally a mix-
ture of 150 grammes of a decoction of walnut leaves (15
grammes to a quart of water) with 20 grammes of glyce-
rine, 5 grammes of chlorate of potassium, and 4 gramme
of salicylic acid in 15' grammes of rectified spirit. Of
this give once or twice daily a. tablespoonful to large fowls.
He also paints the parts with the solution twice a day.
In addition to using any of the above .treatments the

birds should be given soft feed, and in cases where they can
not eat, the food should be given by hand. They should
also be given a stimulating tonic, the following being
recommended: Cayenne pepper, sulphate of quinine, sul-
phate of iron, of each one drachm. Mix and add a little
honey or syrup as an excipient, and divide the mass into
sixty pills. Give each fowl one pill three times a day. Con-
valescent fowls should not be returned to the healthy
flock for at least a month after recovery.
