Thoracic and abdominal aorta, splenic and left renal minimal, left and right 
coronary and right renal moderately effected. 
Case V. Male, 76. Acute infection, likely influenza. 
Thoracic and upper abdominal and right coronary moderate, descending 
branch of the left coronary pronouncedly, splenic, left renal and internal caro- 
tid negative, pulmonary minimal. 
Case VI. Male, 72. Died from cerebral apoplexy. This case was rather ad- 
vanced but was studied with a view of noting the condition of the vessels in 
general in relation to the apoplectic insult. 
Pronounced sclerosis of the aortic arch, atheromatous ulcer of the abdominal 
aorta, splenic and coronaries pronounced with calcification of the latter, right 
renal moderate, left renal, pre fossi sylvian and pulmonary minimal. The sub- 
clavial and common carotid pronounced, the hasalar and vertebral were nega- 
tive notwithstanding the cerebral hemorrage. 
Case VII. Male, 39. Died from pernicious anaemia. 
The aortic bulb at the origin of the left coronary as well as the latter itself 
show minimal localized sclerotic patches, the left common carotid moderate, 
coeliac, both renals and the splenic minimal. The right coronary and prefossi 
sylvii were not studied. 
Case VIII. Male, 47. This was a medico legal .case, the man dying sud- 
denly after falling on the sidewalk. Examination revealed pronounced scler- 
osis and some atheroma of the aortic arch and pronounced sclerotic stenosis 
of the origin of the left cornary. The right coronary was minimally effected. 
The other vessels were free. 
The diagnosis of angina pectoris was established. 
Case IX. Male, 68. Died from carcinoma of the ampulla of the rectum. 
The aortic arch showed minimal sclerosis, the abdominal aorta moderate 
sclerosis with atheromitous ulcers about the original of the renals. The cere- 
bral vessels were not examined but the other vessels revealed no macroscopic 
changes. 
Case X. Male, 34. Died from peritonitis, caused from a perforating carci- 
noma of the stomach. 
The arch of the aorta showed minimal circumscribed slightly elevated yel- 
lowish sclerotic patches. The other vessels were free. 
Case XI. Male, 40. Died from typhoid fever. 
The aorta and the pulmonalis showed moderate circumscribed slightly ele- 
vated yellowish sclerotic patches. The other vessels are not diseased. This case 
is of interest because of the infection which existed, some authorities claiming 
infections, particularly typhoid, as an important etiological factor in arterlo 
sclerosis. 
Case XII. Male, 33. Died from heart disease. This case is of special in- 
terest because the sclerosis was practically limited to the pulmonary arteries 
while the systemic vessels were free. I have reported the case elsewhere. 
(Arch, of Internal Med., April 15, 1909.) 
The aortic arch showed minimal sclerosis but the pulmunary, especially the 
medium and smaller branches revealed a pronounced diffuse sclerotic thickening 
limited to the intima. 
Case XIII. Male, about 50. Died from cerebral hemorrage. 
The coronaries, the basilar, the pre fossi sylvii and the cerebral all pro- 
nouncedly affected. The aorta, the renals and the splenic only minimal
