112 THE MICROSCOPE. 
Dr. W. J. Holland gave an interesting account of the eclipse 
expedition sent to Japan a few years ago. The talk was illustrated 
with many photographs. 
The other members of the society, as usual, had interesting ex- 
hibits of diatoms, vorticellze and zoophytes. 
At the meeting March 12th, about thirty members were present, 
Vice-President C. C. Mellor in the chair. 
Dr. T. L. Hazzard gave an interesting talk on the “ Microscopie 
Structure of the Intestinal Canal,” illustrating his subject with

ised us further particulars for our next issue. 
InpivipuaLity oF THE CeLLt.—The discovery of Schwann in 1839, 
that all animals were composed of cells, marks the birth of the science 
of Biology, and from that day to the present, there has been an 
almost uninterrupted advance in our knowledge of the histology and 
functions of animal and vegetable bodies. But until within compar- 
atively recent years, biologists have looked upon the cell only as an 
integral particle of tissue, much as a mason considers a single brick 
part and parcel of the structure foreshadowed in the plans of the 
architect. More and more, however, the observer of to-day is
