MICROSCOPICAL AND NATURAL HISTORY SECTION. 
Annual Meeting, April 18th, 1887. 
Professor W. C. Williamson, LL.D., F.R.S., President 
of the Section, in the Chair. 
The Hon. Secretary read the Annual Report of the 
Council. 
In presenting the Twenty-ninth Annual Report, the Council 
has again the satisfaction of being able to congratulate the 
members and associates on the continued healthiness and 
increased vigour of the Section. 
At the meetings there has been a very good average 
attendance, better than in many recent years, and there has 
been no lack of original papers, and interesting communica- 
tions to discuss, and exliibits to examine ; and it may be 
confidently asserted that the past session will compare very 
favourably with any previous one. 
As a very full account of exhibits, communications, and 
papers has been printed in the Society’s proceedings, it is 
not necessary to recapitulate them here ; but perhaps special 
mention should be made of the two admirable addresses of 
our president. Professor Williamson, one “ On the present 
state of our knowledge of the Carboniferous Calamitinse,” 
the other “On the structure and development of young 
Roots.” The various records and descriptions of new species 
of Hymenoptera, by Mr. Peter Cameron ; Mr. J. C. Melvill’s 
papers on rare Heterocera, and on two rare grasses discovered 
by him in Scotland; Mr. Bailey’s paper on Ranunculus 
Flammula, and R. reptans and their connecting links ; Mr. 
Rogers’ paper on the varieties of Lastrea Filix-mas ; Mr. 
J. Barrow’s admirably illustrated description of the micro- 
scopical structure of some Seeds; Dr. Hodgkinson’s paper
