m with good ventilation and sunlight.
Dressings and objects coming in contact with him must be burned or
boiled. The diet should be liquid, such as milk, beef tea, soups, and
gruels. The use of cloths wet constantly with cold water, or with a
cold solution of one-half teaspoonful of pure carbolic acid to the
pint of hot water, or with a poisonous solution of sugar of lead, four
grains to the pint, should be kept over small inflamed areas. Fever is
reduced by sponging the whole naked body with cold water at frequent
intervals. A tablespoonful of whisky or brandy in water may be given
every two hours to adults if the pulse is weak. Painting the borders
of the inflamed patch with contractile collodion may prevent its
spreading. The patient must be quarantined until all scaling ceases,
usually for two weeks.

=Malaria and Yellow Fever=

_The Malarial Parasite--Mosquitoes the Means of Infection--Different
Forms of Malaria--Symptoms and Treatment--No Specific for Yellow
Fever._

=MALARIA; CHILLS AND FEVER; AGUE; FEVER AND AGUE; SWAMP OR MARSH
FEVER; INTERMITTENT OR REMITTENT FEVER; BILIOUS FEVER.=--Malaria is a
communicable disease characterized by attacks of fever occurring at
certain intervals, and due to a minute animal parasite which inhabits
the body of the mosquito, and is communicated to the blood of man by
the bites of this insect.

In accordance with this definition malaria is not a contagious disease
in the sense that it is acquired by contact with the sick, which is
not the case, but it is derived from contact with certain kinds of
mosquitoes, and can be contracted in no other way, despite the many
popular notions to the contrary. Mosquitoes, in their turn, acquire
the malarial parasite by biting human beings suffering from malaria.
It thus becomes possible for one malarial patient, coming to a region
hitherto free from the disease, to infect the whole district with
malaria through the medium of mosquitoes.

=Causes.=--While the parasite infesting mosquitoes is the only direct
cause of malaria, yet certain circumstances are requisite for the life
and growth of the mosquitoes. These are moisture and proper
temperature, which should average not less than 60 deg. F. Damp soil,
marshes, or bodies of water have always been recognized as favoring
malaria.

Malaria is common in temperate climates--in the summer and autumn
months particularly, less often in spring, and very rarely in winter,
