usually appears; it is highest on the fourth to seventh day, corresponding to the 
period of most profuse eruption; there is a difference of 1° to 1.5° F. between the 
minimum morning and maximum evening temperature, which difference is main- 
tained until about the tenth to fifteenth day, when the temperature line becomes 
erratic, for at this time it is apt to take sudden jumps up and then as suddenly down, 
while at the same time the average tem^ierature is gradually going down, until by 
the end of the thhd week the patient is entirely free from fever. The Medical Sen- 
tinel (1899, p. 457), speaking editorial!}", refers to the fever as remittent in type. 
Montana . — The fever comes on with or rapidly follows the initiative chill, so that 
upon the first ^fisit the temperature is usually 102° to 104° F. ; it becomes gradually 
higher day after day until it reaches its maximum in 2 to 7 days, when it ordinarily 
registers 103° to 106°; there seems to be a slight evening rise above that of mornings; 
in probably all cases except the mildest, one may be misled in the latter days of the 
attack in thinking the fever abated upon feeling the skin, or by the thermometer 
registered in the axilla, while the rectal temperature shows to the contrary; this dif- 
ference in temperature is apparently caused by the slow, feeble, obstructed circula- 
tion, the exterior and the extremities becoming cool from a lack of blood supply; in 
cases where recovery takes place, the fever begins to abate about the fourteenth day 
and gradually recedes until it disappears, on an average, on the twenty-first day; 2 
cases had subnormal temperature mornings and about 1° of fever at 6 p. m. almost 
during the entire attack.. (Gwinn, 1902. ) 
McCullough ( 1902, p. 226) says that the temperature and pulse assume the form 
of most continued fevers, both gradually increasing, until the acme of the disease is 
reached in nonfatal cases about the end of the second week; very high temperature 
is not usual, ranging from 102° to 106°. 
According to Wilson and Chowning (1902a, p. 132; 1903a, p. 62; 1904a, p. 37) 
after the initial chill, fever rapidly develops, and may reach 103° to 104° F. on the 
second day; it gradually increases and reaches its maximum in from 5 to 7 days, 
when it may register 105° to 107° F. (rectal temperature); the difference between 
rectal and axillary temperature is sometimes as much as 2° F. ; usually a slight even- 
ing increase and morning decrease are noted; the temperature occasionally becomes 
normal or subnormal 18 to 24 hours before death; when recovery occurs, it is by 
lysis, much as in typhoid; the diminution of the fever begins about the end of the 
second week and reaches normal about 2 weeks later. 
Anderson (1903a, p. 507; 1903c, p. 21) states that before the distinct chill there is 
little or no fever in the morning, with a slight rise in the afternoon; after the chill 
there is an abrupt rise, and from then on the fever gradually rises in the evening, 
with a slight morning remission. The maximum is usually reached on the eighth to 
the twelfth day; then, in a favorable case it gradually falls, becoming normal about 
the fourteenth to the eighteenth day, usually going to subnormal for a few days; in 
fatal cases the fever remains high, from 104° to 105° or 106° F., and the morning 
remissions are very slight or not present. 
Gates (1903, pp. 48, 49) reports the temperature for two cases; in one case the 
patient was given small doses of aconite and spirit of nitrous ether and small doses 
of alcohol until the fever was reduced and bowels moved freely; the patient was 
sponged with cool and cold water, as needed for high temperature; the fever ran an 
irregular course, with great variation, reaching at times a temperature 104.5° F., and 
again sinking to 97° F. This low temperature was observed during the last of the 
first week of the disease, at which time the patient was in a state of collapse, being 
almost pulseless and having a hard chill at the tim.e. 
CoMPAEisoxs. — In Texas fever, if the temperature of exposed animals be taken 
once daily — say, in the morning — it will be found that at the onset of the disease it 
will rise within 24 hours from the normal to 104° F. or even higher. In the follow- 
ing 24 hours it may rise to 105° or 107° F. The continued daily record will then
