PREVENTION OF CANCER.

search work being done among the
lower organisms. including fish. rats.
mice. dogs, rabbits and the like, and
these Investigations have developed
many highly Illuminating facts of in
tense interest and significance to the
human family.
Bonnet in 1888 was probably the
first to note and describe a species of
cancerous disease of the thyroid gland
among trout Following this sugges-
tion, Investigators have found that
trout and other fish quite generally
all over the world are afflicted with
what appears to be a carcinoma begin
ming in the thyroid gland and from
there spreading to the adjoining bones
and muscles. The disease attacks
chiefly fish over two years old and the
general trend of opinion appears to
be that its origin is in some. way con-
nected with the food supply.
Gaylord found the disease to be con-
stantly present or endemic IN not less
than 75 per cent of the hatcheries con-
tanning salmonoids throughout the
United States. and that it became epi-
in general from time to time. He also
observed marked variations in the gen.
eral severity and characteristics OF
the disease in different epidemics.
In one hatchery more than so per
cent OF the tumors showed the struc-
ture of carcinoma, while in an en-
demic encountered In another locality
the growth was in general more like
simple goiter.
Marine and Lenhart endeavored. by
a comprehensive series of expert
ments, to discover any possible con-
nection between the ordinary goiter of
fish and animals and the so-called can
cerous affections of the thyroid gland.
They discovered that young fish were
more affected than the old, that the
glandular enlargements were checked
by the addition OF iodine to the water
of the pool and that the removal OF
the fish to an open brook effected
cure. These Investigators consider the
tumors to be directly related to the
water supply, but do not accept the
prevailing opinion that the disease is
true cancer
They consider that there are three
factors which, in some way still OBJ
scure. influence. thyroid enlargement.
namely. limited water supply, over
crowding, and overfeeding with high
ly artificial and incomplete food. They
found the water of the hatchery was
not intrinsicaIly goiterproducing, be-
cause fish did not develop the disease
unless one OF these other factors was
also in operation. That is to say. the
fish must either be fed with an in
complete food, or the pool must be
overcrowded with fish, which in the
end amounts to practically the same
thing, in order to produce the disease.
And II the Incomplete food was re-
placed by a complete food or the over
crowding was corrected. then recovery
took place even though the fish re-
NAMED in the same pool.
The Significance of the above to hui
manity lies in the fact that SO far as
fish are concerned the water of the
stream is synonymous with food. be-
cause normally fish derive their oxy-
gen and all other food matter directly
hence, II too many individuals are
crowded into n given pool or the water
normally does not carry sufficient ma
terial to maintain the group the weak

a deficiency of necessary elements.

some way not yet understood, convert
ed into a malignant disease. But.
granting that they begin as simple be-
nign enlargements, as they undoubted-
ly do, we do not know and are gen
orally quite unable to determine at
what stage an enlargement changes
from the benign into the malignant
type. Every enlargement should be
viewed with suspicion and concern
and should receive prompt attention
at the hands of some competent per

all hypertrophIes; that is to say. to
all and any engagements OF thicken-
ings of tissues anywhere in the body
