The liver In malarial fever Is enlar Cd,
OF dark slate color. and when cut into
the color is of deep bronze. Under the
microscope a large number OF dark pigment
particles are to BIO seen; in many az the
hcratic cells a large number OF pigment
grsnules are deposited.
The liver in uncomplicated cases OF yell
low fever is OF a golden yellow color and
but little blood is TO be found The color
varies with the length OF the attack. Cases
winch ave died early IN the attack are
frequently engorged with blood. Again,
we meet with n notified liver, the yellow
color predominating These are the cases
which have suffered from previous Diseases.
especially from malarial fever This golden
| yellow color, which We find uniformly
| throughout the liver IN yellow fever. is
due to fatty degeneration of the proto-
| piasm of the organ and also TO a fatty in
| filtration, the Dletanlorphosis not always
| being complete. With some specimens of
| the liver placed under the microscope j
have noticed that the structure OF the liver
seemed entirely gone, yet. after washing
the specimen with ether the original struc-
! ture would reaprear, showing fatty infii-
| uatlon Again, the treatment OF other
/ specimens with ether had no such effect,
| the cellular protoplasm having been replace

acted upon by acids or alkalies. piece of

readily dissolved, the decocticn having the

action is produced by the same solution on
the liver Of yellow fever. 6ecocCion of
the liver may be made with either alcohol
or water, the decocticn of The malarlal
liver being of yellowish brown; that Of
yellow fever of golden yellow. The fatty
infitration Of many OF the tissues in yell
low fever points TO the fact that the al
bumenoid elements of the blood have UNI

their tissue also infiltrated with fat.
THE KIDNEYS IN HEMORRHAGIC MA
LARIAL FEVER.
The exterior of the kidneys are of dark
blush red presenting here and there on
their surface dark blush spots: when open
ed the same dark, blush red color is found.
The whole organ is heavily coneested; in

Illumination. All blood vessels from the
largest to the smallest, are distended with
blood. There Is evidence Of hemorrhage
in the malpighian corpuscles filling u
large number OF the tubuli uripiferi with
coagulated blood. These latter structures
are IL addition, desquamated and almost
totally denuded of their pavement endotbe-
lium, and in many Instances entirely so.
In yellow fever the color of the kidneys |
is somewhat lighter than usual, owing To |
the presence OF fat. At times we find a
