layer of the epitlielium to the surface passing between the 

 interstices of the larger cells. Between the two are situated 

 the third or forked kind of cells, if such they can be called, 

 consisting of a fusiform body Avith delicate processes, which 

 arise from either pole and in varying number. Those spring- 

 ing from the peripheral pole penetrate between the calyx-cells 

 to the free surface of the epithelium ; and they are frequently 

 divided once or twice dichotomously. The processes arising 

 from the opposite or centrad pole, and which in appearance 

 resemble an axial nerve-fibre, also subdivide once or twice, 

 and appear to terminate in the connective-tissue substratum 

 of the papilla. 



A branch of the gustatory nerve on entering the papilla, 

 divides into a leash of branches which divide and subdivide, 

 till at length they form or terminate in a sort of cushion 

 upon which rest the central processes of the cylinder- and 

 furcate-cells. In this nerve-cushion may be observed very 

 delicate fibrillae, but whether or no these are continuous with 

 the inner processes of the furcate-cells has not been ascer- 

 tained, though there appears to be every probability in 

 favour of the view that they do.

 Eberth, of Zurich. 



This is an interesting paper just at the present time, when 

 the structure of the liver is so much under discussion. 

 The researches of Hering, and the natural injections of 

 Chrzonseuzezki, have shown that the finest branches of the 

 gall-ducts ramify between the ultimate liver-cells in mam- 

 mals, bounded by only two cells, whose sides are grooved to 

 form the channel ; in other vertebrata surrounded by a larger 

 number of cells, large in size relatively, but still more closely 

 approaching a typical gland duct. Eberth has already pub- 

 lished in ' Virchow's Archiv' an account of his investigations, 

 in which he points out the complexity of the structure of the 

 mammalian liver, as compared with that of Batrachians in 

 particular. In the present communication he gives a special 

 account of the comparative histology of the liver, illustrated 

 with a beautiful coloured plate. The two points which he 

 discusses are : 1st. The gall-capillaries, their structure, and 

 distribution. 2nd. The pigment of the liver, and its varia- 

 tion in the amphibia. He alludes to Hering's paper with 

 high praise, but at the same time expresses a disagreement 

 with him as to the lateral blindlj^-ending process of the
