sarcoma. These names are common

| to the location and character of the
new growth.
A number of letters of inquiry in
regard to this disease have been re-
ceived by the veterinary of the Ar
kansas Agricultural Experiment Sta
Iion from cattle owners from various
sections of the state, and 1t is to be
hoped this article will cast some light
upon this seemingly very prevalent
disease among cattle of the state.
AT very early date is was known
to few that the disease was due to
a specific organism, and because it
belongs to the higher forms of bac-
terial life, it was discovered by
botanist, DR.. Harz. Professor Boil
linger was the first to isolate and
describe this organism as it occurs
in connection with the disease as it
is found in cattle. DR.. Israel first
found the organism in connection
with similar disease in man. In
cattle this disease is widely distribut-
ed throughout the world, particularly
in America and Europe. 1t is, how
ever, rather difficult to collect re-
liable statistics, because the vast ma
jority of the animals which suffer
from this disease are slaughtered
for home consumption. The U. s.
Bureau of Animal Industry reports
give one animal in 1000 in this coun-
yryh1 nh in, m mil tc ~
estimate since the statistics were
taken at the federal packing houses,
and as before stated the greater num-
Der Of cattle suffering from this dis
ease are slaughtered by our local
butchers and placed on the market
for home consumption.
Etiology (cause of this disease) is
the rayfungus or actinomyces. The
rayfungus is principally known only
as parasite associated with the dis
ease. A complete rayfungus can be
detected with the naked eye in pus
properly collected from an actinomy-
cotic tumor and spread on a glass
slide. The manner and form in which
this organism gains entrance into the

is quite probable that they enter the
body by the digestive tract, as in
most all cases it is during the she'd
ding of teeth, or shortly after, that
the animal shows evidence of dis
ease, and no doubt exists but that
certain food stuffs will convey the
infection, such as barley, straw and
rye. In the opinion of the writer,
which opinion is based upon observa
ton, in the vast majority of the cases
it is abrasions and wounds of the
head that become infected My OBJ
servation is that this trouble is quite
common in dairy cows and the infec-
ton is located in those regions of
the head that are most likely to be
abraided or wounded by the stanton
or the halter.
Definition-ln order to properly I'M
derstand any disease under consider
alton it is first well for one to get
proper definition of such disease fix
ed in the mind; and such definition
should lead up to some of the char
acteristics found in the symptoms of
the disease as well as to the pathol.
ogy of the disease. By pathology we
mean that abnormal condition of the
body or parts of the body existing at
the time of the disease.
Actinomycosis Qumpy jaw is a
| chronic infectious disease character

in the region of the head
Symptoms-These will depend to a
| great extent on the localization of
| the disease The disease may be
| found involving the bones or soft
structures of the upper or lower jaw,
| pharynx, lungs, liver, spleen, pam
creas, skin or udder, or the Emphatic
| glands of any part of the body. The
tongue is rarely involved in this
country, but the bones and soft struc-

| ed is likely a small enlargement in
the region of the head or jaws which
may or may not cause a difficult pre-
hension gathering food) and mastica-
| ton. After the disease is well estab-
lished you will find loss of facial
I symmetry and If the enlargement is
palpated you will find that you are
| dealing with hot, firm, painful en-
largement. In the course of one, two.
four or six months this tumor mass
will rupture either externally or in
| ternally. If the rupture takes place
externally, very offensive discharge
takes place, usually mixture of
blood and pus, and the enlargement
| will subside to certain extent. The
animal gradually emaciates (becomes
poor) due to the fact that mastica-

When the lungs becomes the seat of
the trouble, there is usually a cough

animal gradually emaciates, and is
easily exhausted. In this form of in.
