formation in a subject of 52 years of age, on the left side of 
the lower part of the neck. The base or lower part of this 
sac, which was shaped like a pear, was below the left cla- 
vicle; and the upper part, which was wrinkled (effilée), 
had an aperture furnished with, a kind of valve, which 
was near the commencement of the gullet. Its contexture 
had more density than the esophagus. From the aperture: 
to the extremity the length of this crop was two inches and 
a quarter in a relaxed state; its greatest diameter was an 
inch and three quarters ; the aperture was three-eighths of 
an inch. ; 
The size of this crop was considerably increased by infla- 
tion. It might contain about a pound of water ; and when 
filled, the water could not be evacuated without a strong 
pressure of the hand. 
The meat and drink taken by this man passed at first mto 
this sac, and remained there for more than two hours before 
passing into the stomach. 
M. Thielow: has developed in this memoir the reasons 
why this sac may be considered as a crop. He has given a 
description and a drawing of it in the second edition of his: 
work upon anatomy and pathology, published last Easter 
fair at Leipsic *.
