THE MICROSCOPE. 217 



will find a schematic cell. Now I think, I do not know, that there 

 is some reason in that scheme. Pfliiger goes into quite a discussion 

 in nerve terminations, in Strieker, page 308, but there is in his own 

 showing room for more study. 



If you will look at my osmic acid preparation of the bronchial 

 epithelium, you will find in some cells by oblique light and very 

 cautious focussing a fine line which seems to connect the nucleus 

 with the tissues beyond, and this fine line passes into one of the 

 processes of the epithelial cell. I find it in by no means all cells, 

 but sometimes I see it or think I do very plainly. Now in some of 

 these lining membrane cells I think I see just such appearances. 

 In many cells a long process is distinct, in some cases twice as long 

 as the cell-body. There are also cells of connective tissue in con- 

 nection with the other processes of the cell. I sketch cells and send 

 them. It may be that my little drawings suggest Pfliiger's, but all 

 pictures of horses should resemble each other in having four legs. 

 I know this is no Heitzman frame-work. It may be that I am mis- 

 taken but I think as I say. I am not fully satisfied, hence I ask 

 you. 



Also in the same mucous membrane there are cells above two 

 diameters larger than the connective tissue corpuscles which send 

 processes to the smallest capillary walls and communicate only with 

 each other and receive the very finest nerve fibres. This I am quite 

 certain of. 



But to state my conclusions or rather lucubrations in a pro 

 forma shape: 



There is an epithelium lining the sow's womb made up of cells 

 three to five times as long as broad, so set that seen from above, 

 they resemble pavement cells. There is but orte line of these cells. 

 Some cells present ciliation, some cell contents and distinct 

 nucleus, some both nucleus and nucleolus as well. Many cells can 

 be traced as branched into communication with connective tissue 

 corpuscles. There are certain cells of a type distinct from these 

 presenting an open mouth. In these the cell contents is wanting. 

 The nucleus stands free in these cells and presents a process which 

 passes beyond the cell.
