The foregoing remarks upon some of the organisms studied 
during the session are necessarily limited by the space at my 
_ disposal. In conclusion, it may not be amiss to state the 
medium which was found most suitable for mounting the 
more delicate parts for examination under the microscope. 
After trying several media, it was found that the following 
gave excellent results, allowing the fine plumose setz to be 
clearly seen: Glycerine, 1 part; alcohol, 1 part; distilled 
water, 2 parts. Gold size should be used for making the 
cells and for sealing them after the cover-glass has been put 
_ on, and when dry a coat or two of good asphalt cement should 
be added. 
My best thanks are due to Mr T. Scott, F.L.S., Naturalist to 
the Scottish Fishery Board, and an Honorary Member of the 
Society, for revising the classification in the above Report.

At the concluding winter-evening meeting of the Society for 
the present session, on April 24, a paper was read by one of 
our honorary members, Mr Mark King, on “The Flora of the 
Shores of the Firth of Forth.” In submitting his communica- 
tion, the writer said that he had hoped to make it more worthy 
of the subject, but that he found his years of threescore and 
thirteen were not equal to the task. This paper, which is now 
published in our ‘ Transactions,’ is a valuable contribution to 
a large and important subject, and betokens much labour and 
careful observation, conjoined with botanical skill, on the part 
of the writer. Shortly after this communication was made to
