On April 19 the soreness became much worse, and shooting* pains 
began radiating from the axilla through the shoulder, down the arm 
and side of the body. Patient had a severe chill, followed by high 
temperature and aching pains in back. These gradually extended to 
the whole bod}". Patient felt better on April 20 and 21 in the morn- 
ing, but was worse again in the afternoon. 
On April 22 she was brought to St. Patrick’s Hospital, Missoula, 
and placed under the care of Dr. McCollough. On the evening of 
April 22 spots began to appear first on the wrist and ankles. On the 
morning of April 24 spots were well developed all over body, being 
of the small petechial type and quite rosy in appearance. Patient’s 
mind at this time was quite clear (except for slight wandering imme- 
diately after awakening) and remained so until a few hours before 
death. 
- Patient examined April 24, 9 a. m., by Drs. McCollough, Gwinn, 
Spottswood, and MTlson. Fresh blood showed a few red cells which 
contained ovoidal bodies with amoeboid movements (an alcohol lamp 
was in front of concave mirror). Count showed — 
Red blood corpuscles 4, 920, 000 
Leucocytes 7,400 
Hemoglobin per cent. . 100 
Cultures with blood taken from the ear Were made on agar and 
serum. These showed no growth after three days in the incubator. 
Patient was examined again April 26 by Dr. Wilson. Condition 
was apparently the same as when last seen except the patient was 
more restless. Fresh blood showed many more infected cells than that 
collected April 24. Count showed — 
Red blood corpuscles 4, 600, 000 
Leucocytes 7,600 
Hemoglobin j)er cent. . 80.
