III tlie rabbit and the mouse small differentiations of the mucous 

 membrane occur between the orifices of the pyloric glands as well 

 as betw^een those of the fundus glands, to which no better name 

 could be given tiian tiial of /•//// of the stomach: slightly promiiuMit, 

 blunt ele\ations, rich in i)lood-ca|)illaries and supported by a uieshwork 

 of connective adenoid tissue, l)ut in w liich iKdiiiug of a cciili-al 

 chyle-vessel, nor of smootli muscle-tlbres coidd be detected. They 

 were clothed willi a single layer of cylindric epithelium, of which the 

 cells, situated on or in the neigiil)ourhood of the iqjper part of such 

 a gastric villus carried outside of the above-mentioned Iwundary 

 layer of the modei-n histologists, an outer Vnnh, which seemed to 

 consist of closely [)acked fibrils, probably cell-processes. 



Each cell has its own apparatus; at the edges of the cells, where 

 the "Schlussleisten" lie between the cells, the fibrils are wanting. 

 Tangential sections of the upper part of those epithelium-cells of the 

 stomach (sections of 1 ƒ« were studied J showed tinely speckled 

 pentagonal and hexagonal figures, separated by pretty wide furrows. 

 They were stained violet with diluted Ivibbekt's pliosphormolybdenons 

 hematein. 



The length of these bundles of cell-filaments is rather different in 

 the various cells, but for one single cell pretty regular; tiiey form 

 externally gently convex lines; each cell is, as it were lined with a 

 dome-siiaped i-alhcr ihick coxeriiig. There is not the least donbl thai 

 we have }iot to deal with adhesive gastric contents. These lie on 

 these dome-shaped elevations and are separated from it by a small 

 interstice, which was prol>ably originally caused by shrinking during 

 the process (alcohol, carbondisulphide, paraffine, etc.) 



Tiie different "outer limbs" of the cells may be grouped between 

 two extremes: on the one side the extended cell-processes are seefi 

 to diverge more or less, i)est to be coiiij)are(l to a short brush witii 

 diverging hairs ; on the other side we notice the pseudopodia drawn 

 in, settled like stiff little hairs on the cell "membrane", and then such 

 an outer limb resembles the well-known striated border of the resorb- 

 ing epithelium-cells, or expressed in a more neutral expression : the 

 surface-epithelium of the intestine. 



These epithelium-cells of the stomach Avith outer limbs now 

 show in the preparations a peculiarity at their base which has 

 been noticed and photographed l)y Carlier ^), but the reality of 

 which has been doubted amongst others, bv Von Ebner in Kölliker's
