DR. HERBERT WATNEY ON THE MINUTE 
Fig. 42. Camera Lucida: obj. 8, X 600 nearly — oc. iil, obj. 9. 
Vertical section of the upper part of one of the plicse villosae ; from the 
stomach of a dog. 
The epithelium is drawn diagrammatically. 
v. Blood-vessel. 
m. Muscle-fibres. 
e. Endothelial cells. 
The disposition of the muscle-fibres and the perivascular spaces are well seen. 
Fig. 43. X 20 times nearly. Vertical longitudinal section of the point of transition of 
the stomach and intestine of a dog. This drawing was made from two 
specimens, and is therefore slightly diagrammatic. 
M. Part of the muscular wall. 
SM. Submucosa. 
mm. Muscularis mucosa. 
Ic. Lymphatic follicles. 
The coiled tubes are seen to break through the line of the muscularis 
mucosa and become continuous with the glands lying in the submucosa 
(Brunner’s glands). 
The ducts of two lobes of Brunner’s glands are seen between the crypts of 
Lieberkuhn. — I have to thank my friend Mr. Hope, of St. George’s Hospital, 
for this drawing.
