Gates (1905, p. 115) reports endocarditis as sequela in his case 8. 
One of the cases of 1903 had not fully regained the use of his legs 
in the summer of 1904. 
Autopsies. 
The following autopsies have been made: 
Idaho . — Apparently none. 
Montana. — 1897: Case 35, by Buckley, reported briefly in Wilson and Chowning, 
1903a, page 33, and Anderson, 1903c, page 13. 1902: Case 89, by Wilson, Longeway, 
Brethauer, and Buckley, reported in Wilson and Chowning, 1903a, page 50; case 91^ 
by Wilson, Brice, Longeway, and Buckley, reported in Wilson and Chowning, 
1903a, page 52; case 93, by Wilson and Spottswood, reported in Wilson and Chown- 
ing, 1903a, page 54; case 94, by Wilson, Chowning, and Buckley, reported in Wilson 
and Chowning, 1903a, page 56; case 97, by Chowning, reported in Wilson and 
Chowning, 1903a, page 55; case 107, by Wilson and Longeway, reported in Wilson 
and Chowning, 1903a, page 47. 1903: Case 120, by Anderson, Wilson, Gwinn, Mills, 
Olson, Pixley, and Spottswood, reported in Anderson, 1903c, page 32. 1904: Case 
11, by Ashburn, Mills, and Stiles, reported in Stiles, 1905, p. 109-110. 
(?) : Case — , by Hanbidge and Gwinn, reported briefly in Gwinn, 1902. 
(?): Case — , briefly referred to by Gwinn, 1902. 
Pathology. 
Idaho . — “The pathological conditions, as at present understood, may be described 
with a large-sized interrogation point.” — Maxey, 1899, pp. 434-435. Fairchild (1896) 
has seen no autopsies. The lesions, so far as Figgins (1896, p. 64) knows, are con- 
fined to the skin. 
Montana . — Gwinn (1902) reports slight enlargement of the liver and kidneys, 
together with slight degeneration, in one case on autopsy. 
The gross lesions are very uniform; intense rigor mortis appears early (Wilson 
and Chowning, 1904a, p. 41). 
The changes are those which can be ascribed to interference with capillary circu- 
lation; the extravasation into and pigmentation of the skin account for the persist- 
ence of the spots for long periods after the recovery of the patients; there, is acute 
parenchymatous degeneration of the heart muscles, spleen, liver, and kidney; the 
central nervous system is but little affected (Wilson and Chowning, 1904a, p. 43). 
Anderson (1903c, p. 38) summarizes the post-mortem findings in 7 cases (6 of 1902, 
1 of 1903) in the Bitter Boot Valley. 
Rigor mortis was intense in cases 89, 91, and 93 (Wilson and Chowning, 1903a, 
pp. 50, 52, 54), but not in case 120 (Anderson, 1903c, p. 32).

CLINICAL HISTORIES. 
During my work I did not take clinical notes, as I had so many 
other things to occupy my time. Clinical notes were, however, taken 
b}^ the attending physicians and to some extent also by Doctor Ash- 
burn. As both Wilson and Chowning (1902a, 1903a, 1904a) and Ander- 
son (1903a, c) had studied the clinical side, and as I was looking especially 
for the life history of the parasite as a basis for prevention, I natu- 
rally neglected to go into an especially detailed clinical study, blood
