Mr. A. W. Bennett called attention to the first number of the 
“ Phycological Memoirs,” a serial which it was intended to bring out 
regularly as a record of the work done in the British Museum in the 
department of Algae, edited by Mr. G. Murray. 
Prof. F. Jeffrey Bell mentioned that in response to an application 
made to the Geological Society for some portions of their Proceedings 
to complete the series, the Council of that Society had very kindly 
forwarded the volumes asked for, together with a catalogue of the books 
in their library. 
Mr. E. M. Nelson exhibited one of Messrs. Watson’s Edinburgh 
Student’s Microscopes to which several novelties had been applied (see 
p. 236). 
The President thought this was a very excellent form of Microscope, 
especially as it was a low-priced one. It seemed to be particularly 
applicable to the examination of long lines of sections such as were now 
being so much used. He did not know whether the slide could be passed 
along without coming into contact with the milled head, as so often 
occurred where this was not carefully kept below the level of the surface 
of the stage. In his own work he found he was constantly being brought 
up by the slide touching the milled head when he had occasion to examine 
a series of sections. 
Mr. Nelson said this defect had been noticed and was obviated in 
the model before them, where the milled head had been kept just clear 
of the stage. Though this Microscope was so convenient it did not cost 
as much with the mechanical stage as a smaller one of similar appear- 
ance did without it — the price complete, with the revolving nose-piece, 
being 111 . 10s. 
Dr. W. H. Dallinger thought these additions were no doubt a great 
improvement to the original form of this Microscope, which appeared to
