heter. If a soft
rubber or elastic catheter is used with reasonable care, little damage
can be done, even by a novice. The catheter should be boiled in water
for ten minutes, and after washing his hands thoroughly the attendant
should anoint the catheter with sweet oil (which has been boiled) or
clean vaseline and proceed to introduce the catheter slowly into the
urinary passage until the urine begins to flow out through the
instrument.

A medium-sized catheter is most generally suitable, as a No. 16 of the
French scale, or a No. 8-1/2 of the English scale.

=BRIGHTS DISEASE OF THE KIDNEYS.=--Bright's disease of the kidneys is
acute or chronic, and its presence can be definitely determined only
by chemical and microscopical examination of the urine. Acute Bright's
disease coming on in persons previously well may often, however,
present certain symptoms by which its existence may be suspected even
by the layman.

=ACUTE BRIGHT'S DISEASE; ACUTE INFLAMMATION OF THE KIDNEYS.=--Acute
Bright's disease is often the result of exposure to cold and wet.
Inflammation of the kidneys may be produced by swallowing turpentine,
many of the cheap flavoring extracts in large amounts, carbolic acid,
and Spanish flies; the external use of large quantities of turpentine,
carbolic acid, or Spanish flies may also lead to acute inflammation of
the kidneys. It occurs occasionally in pregnant women. The contagious
germ diseases are very frequently the source of acute Bright's disease
either as a complication or sequel. Thus scarlet fever is the most
frequent cause, but measles, smallpox, chickenpox, yellow fever,
typhoid fever, erysipelas, diphtheria, cholera, and malaria are also
causative factors.

=Symptoms.=--Acute Bright's disease may develop suddenly with pallor
and puffiness of the face owing to dropsy. The eyelids, ankles, legs,
and lower part of the belly are apt to show the dropsy most. There may
be nausea, vomiting, pain and lameness in the small part of the back,
chills and fever, loss of appetite, and often constipation. In
children convulsions sometimes appear. The urine is small in amount,
perhaps not more than a cupful in twenty-four hours, instead of the
normal daily excretion of three pints. Occasionally complete
suppression of urine occurs. It is high-colored, either smoky or of a
porter color, or sometimes a dark or even bright red, from the
pressure of blood. Stupor and unconsciousness may supervene in severe
cases
