ON 'I'lnC STOMACH GT-ANDS OF THE KAT AND RABBIT 
Lcpus caniculus, and to (listin<4uish the cardiac and pylorus portions. He 
stated that the Mucous Membrane of the former is thick anti tlie surface 
tufted. 
In I 87 1 , Rollett studied tlic stomach from a physiological side, and wrote 
that it is impossible to find a perfectly empty stomach among rabbits, and that 
even when fed with milk only, solids are to be found in the stomach. 
Langley and Sewell, in 1 879, tlivided the Stomach of Lepus caniculus into 
four regions. 
In 1889, Edelmann found that in Lepus timidus the cardiac glands are 
absent. Ikit as written above, I have, in the junction of the Oesophagus and 
the fundus parts, found a few cardiac glands. He further says on the Fundus 
glands of hares, "The fundus glands have large cells which in many cases are 
triangular or rounded on one side and contain large nuclei. They are not 
affected by Eosin staining and only show a weak red colour." He could 
find no cardiac glands in Lepus caniculus. 
Because specimens are so easy to obtain, many results have been gained 
by histologists which generally point to the same conclusion and I will there- 
fore not quote them further. 
In the foregoing lines, the chief points of structural difference of the 
gastric pouch of the rat from the rabbit's has, as I believe, been pointed out, 
and we will now turn to the summimg up of 
I) The characteritics of the rat's Stomach and the Duodenum, 
as follows : 
1. ) The stomach is divided into two parts equal in capacity ; the proxi- 
mal part constitutes the cardiac sac and the Distal part answers to 
the Ventricle in other mammals. 
2. ) The cardiac sac is distinguishable from the Oesophagus as regards 
its microscopical as well as macroscopical structure ; it is represented 
by a basal expansiou of the Oesophagus. 
3. ) The boundary ridge which marks off the two divisions of the sto-
