OXYGEN. ' 
Oxygen was repeatedly resorted to in emergencies in 190-i with 
temporary good effect. 
BLEEDING. 
Case 11 (1901) was bled twice with very marked temporary relief. 
On June 27. p. m.. about 12 ounces of blood were taken, after which 
the patient had a good night's rest: the next morning the spots were 
much lighter in color. On June 28, p. m., about 1 ounce of blood 
was taken, followed by noticeable temporary improvement; the next 
morning the spots were lighter, but the patient died later in the day. 
SUPPORTIVE TREATMENT. 
“As supportive treatment as well as germicidal, and having a particular action on 
the blood, I have found useful: E. hydrarg. bichlor., gr. i; liq. pot. arsenitis, 5 iu 
tinct. ferri chlor., 5 ss. ; acid phos. dil., 5 i: syr. limonis q. s., 5 vi. M. sig. Tea- 
spoonful in wineglass of water four times a day. 
“In addition to the above medication, the special symptoms require careful treat- 
ment best adapted to such complications individually.” — McCullough, 1902, p. 228. 
Prevention. 
“In the way of prophylaxis, I have advised an occasional dose of calomel, the 
drinking of boiled water, and thorough protection against cold and Avet.” — Gwinn, 
1902. 
“If, as seems very probable and almost proA'ed, the tick is the means by which 
the disease is spread, the question of the prevention of the disease resolves itself 
into the destruction of the tick. This is an almost impossible task over such a large 
area, especially of such varied topography. When conditions Avill permit, burning 
the undergroAvth and stubble will be an effective method for the destruction of ticks. 
This may be done either in the early fall or, preferably, in the early spring, when 
the ticks are just beginning to move about.” — Anderson, 1903c, p. 41. 
“In view of the almost certain role of the tick in the conveyance of pyroplasmosis 
to man, measures should be taken to reduce the numbers and limit the spread of this 
arachnid. The burning of underbrush, sawdust, etc., wherever practicable, is recom- 
mended. Persons going into the brush in the infected area should use all possible 
precautions to preA’ent ticks from biting them. As soon as a person is bitten by a 
tick, the arachnid should l>e removed and the wound cauterized by 95 per cent car- 
bolic acid.” — Wilson and Chowning, 1904a, p. 56. 
Definite statements regarding prevention can not be made until the 
cause of the disease and its method of transmission are definitely 
known. All that can be said at present seems to be that people in the 
valley should take the best pos.sible care of themselves during the 
spring months, and in case one member of a family is taken sick no 
other person should occupy the bed with the patient. 
Sequelv. 
Idaho . — Dubois (1896) states that tio constitutional symptoms are left. The only 
sequela which Maxey (1899, p. 438) has noticed is a little stiffening of the knee 
joints, lasting some weeks.
