A pitted or sacculated appearance of various por- tions of the interior of the thoracic aorta with thinning of its walls at some parts; the lining membrane roughened at the spots affected; the roughening, however, is not of an athero- matous character, hut due to the membrane being thrown into delicate rugse, as if from contraction of the middle and outer coat. 4. Enlargement and softening of some glandular body adjoining the vessels at the base of the heart. Within the above four headings is comprehended everything abnormal that I have been able to detect, which seemed to imply any connection with the state of the blood under consideration.

These on closer examin- ation prove to be the male and female of the same parasite: the male worm being from one to two inches long, and y^th to Voti1 of an inch in diameter at the widest part; and the female from two to three and a half inches long with a transverse measurement of from Void1 to 7yth of an inch.
