Mr. Slack thought it might be termed an oblique unilateral illu- 
mination. 
Mr. Wenham said it was the only plan by which the object could 
be obliquely viewed by the central portion of the object-glass. At the 
suggestion of the President, Mr. Wenham then drew a more enlarged 
diagram, showing clearly the method of mounting and the position of 
the object upon the slide. 
The President announced that the Council was endeavouring to 
arrange for a scientific meeting to be held on Wednesday, April 14 — 
subsequently changed to 21st; also that at the next ordinary meeting 
of the Society he hoped to be able to read a paper " On some New 
Contrivances for the Study of Spectra, and for applying the mode of 
Spectrum Analysis to the Microscope." 
The Secretary, Mr. Stewart, called the special attention of the 
Fellows to some extremely beautiful preparations of Polycistinss 
exhibited in the room by Mr. Stephenson. Some of them were new, 
and some were very delicately mounted, preserving the spines in a 
very perfect manner.
