758 General Notes. 
versity, may serve to illustrate the importance and the fruitful- 
ness of the methods of microscopic physiology. 
Starting from the well-known facts of gland histology and phys- 
iology where it has been now for long known that activity and 
rest produce corresponding visible changes in their contents, etc., 
the authors sought to ascertain whether some discoverable change 
in the active (or worked) nerve cell could not also be distin- 
guished. 
Hodge reports as a result, that a marked shrinkage of the nucleus 
occurs in worked nerve cells over those not worked; a shrinkage 
amounting sometimes to 33 per cent. In brief :— 
“,, The nucleus and cell body both decrease in size as a result 
of stimulation. 
“2. The protoplasm of the cell becomes vacuolated as a result 
of stimulation. 
“3. Differences appear in staining.”
