out 3 peripheral segments and originate a central cell. The central 
cell now divides into an outer and an inner cell. The latter is 
the first cell of the axial row. The outer cell grows considerably, 
and again the 3 peripheral segments and the inner cell are cut off 
The latter divides into an inner and an outer cell. Thus the 
second cell of the axial row arises just as did the first, and KUHN 
holds that all subsequent cells of the axial row are produced in the — 
same manner. 
In 1872 JANCZEWSKI (9) made a study of the archegonia - 
several mosses. He names 2 species of Sphagnum, Atrichum (Catha 
rinea) undulatum, Bryum crudum, Funaria hygrometrica, and Phas- 
cum cuspidatum. JANCZEWSKI’s account of the development of 
these mosses is very brief. He mentions only the chief points, and : 
gives no details. It is unfortunate also that the paper has no illus- 
trations. In regard to Atrichum undulatum, Bryum crudum, Funa- 
ria hygrometrica, and Phascum cuspidatum, his chief points are 
as follows: There is development by an apical cell with 2 uw a 
- faces, producing a few-celled structure which at this time cant ; 
be distinguished from a young antheridium. In the uppermos
