' PLEURAL CAVITIES. 
No adhesions were reported in cases 107, 89, 91, and 120. In case 93 the pleura 
was intensely adherent over entire surface of lioth lungs; the adhesions were very 
thick and fibrous; there was a history of pleurisy several years before. (Wilson and 
Chowning, 1903a, pp. 47, 51, 52, 54; Anderson, 1903c, p. 33.) 
In 190d the pleural cavities of case 11 were normal except a few 
adhesions between left lung and pericardium. 
Comparisons. — In canine piroplasinosis, the peritoneal and thoracic cavities may 
contain fluid (Hutcheon); sometimes there is brownish serous exudate in thorax; 
in Lounsbury’s chronic case there were pericarditis and j^yothorax. 
LUNGS. 
See also Gangrene; page 50. 
Wilson and Chowning (1904a, pp. 41, 42) report hypostatic congestion; all the lungs 
show considerable congestion and swelling of the capillaries; many red blood cells 
containing parasites are present; in most cases many phagocytes are found which 
have taken up infected red cells and pigment granules; in one case ther.e was con- 
siderable broncho-pneumonia; pleura was normal. 
Anderson (1903c, pp. 33, 38) reports that the plurae are normal and do not contain 
excess of fluid; lungs show hypostatic congestion, occasionally pneumonia; in case 
120 there were no consolidated areas, except a few points resembling emboli. 
See also Complications, page 87. 
Upon autopsy, the lung tissue incase 93 was fully crepitant; there was slight hypo- 
static congestion on both sides; in cases 89 and 91 both lungs were normal, except 
hypostasis on both sides; in case 107, the lungs were apparently normal, no pneu- 
monia (Wilson and Chowning, 1903a, pp. 47, 51, 52, 54). Incase 120, the lungs were 
normally inflated, no consolidated areas, except a few points resembling emboli 
(Anderson, 1903c, p. 33). 
During the season of 1904, case 2 died of edema of the lungs; in case 
3 also edema of the lungs developed; in case 8, slight edema of the 
lungs developed; there was edema of the right lung May 29, and on 
May 30 both lungs were edematous. In case 11, on autopsy, the right 
lung was lead color on upper surface, very dark posteriorly; several 
dark spots one-eighth inch in diameter anteriorly, but apparently old; 
entire lung edematous; posterior portion extremely congested, in a 
condition of hypostatic pneumonia, and sinks in water; left lung shows 
same appearance as right, except pneumonic area is less marked and 
less extensive. 
Comparison. — In Texas fever the lungs are, as a rule, healthy; there is, in many 
cases, pulmonary edema, with or without emphysema, noticeable after death; in a 
few instances foci of dark red hepatization were observed in one of the principal 
lobes, which involved one or several lobules. (Smith and Kilborne, 1893, p. 26. ) 
In canine piroplasinosis the lungs are rarely affected (Hutcheon); Nuttall noted 
edema and pinkish frothy fluid in the bronchi and trachea; in France apoplectiform 
foci have been found; in young dogs dying quickly, usually there are acute edema 
and reddish foamy secretion in bronchi and trachea. 
Hypostatic lobar pneumonia herds have been recorded in carceag.
