INTRODUCTION. 
Again there has been an increase in the number of titles, although less 
marked than in the two previous years, due not so much to purely zoo- 
logical papers as to papers relating to human pathology, chiefly cancer 
and malaria. An idea of the extent of work on this subject may be 
obtained by referring to page 26. 
Under Anatomy, the most important papers of the year appear to be 
those by RiiUmbler on Foraminifera. Gould confirms Greeff’s obser- 
vations as to the foam-like structure of the protoplasm. Zaciiarias 
returns to the views of Ehrenberg and Saville Kent, abandoned for some 
time, regarding the structure of Volvox. Under Embryology we may 
draw special attention to Brauer’s account of the encystation of Actino- 
sphcerium. Under Physiology, there are some valuable papers on diges- 
tion and digestive ferments by Hartog & Dixon and Greenwood & 
Saunders. Ryder’s experiments on Euglena viridis , under abnormal 
conditions, when growing, but restrained to two dimensions of space, have 
led to interesting results.
