SECTIONAL SECRETARIES’ REPORTS. 
The following Reports and Records of the various subjects 
dealt with at the Lectures during the past Session have been 
kindly provided by the Honorary Secretaries of the Sections :— 
BOTANICAL SECTION. 
On December 18th, Professor J. Lloyd Williams, D.Sc. (of the Botany 
Dept., the University College of Wales, Aberystwyth), delivered a Lecture 
entitled “The Life History of the Laminariacec,’? ‘The more common 
British species of the family of Seaweeds were interestingly described and 
illustrated. A brief summary was given of the results of many years’ care- 
ful observation, by the lecturer, of the life histories of these plants. The 
most important feature of the lecture was the Professor’s discoveries relating 
to the reproduction and development of the embryo in some of the species, 
which were fully illustrated by original slides. 
The second Lecture of the Session was delivered on March 11th by Miss 
G. Wigglesworth, M.Sc. (Botany Department, Manchester Museum), her sub- 
ject being ‘‘ Aquatic Vegetation.’? The lecturer demonstrated by means of 
lantern slides and specimens from the ‘‘ Charles Bailey’? Herbarium, how 
aquatic conditions modified the structure of plants. The main differences 
between marine and fresh water plants were briefly dealt with, whilst the 
principal structural features and distribution of selected species were de- 
scribed and illustrated. 
ZOOLOGICAL SECTION. 
The first of the Sectional Meetings was held on October 9th, when Mr. 
_G. A. Dunlop, Sub-Curator of the Municipal Museum, Warrington, lectured 
to a large and appreciative audience on the subject of ‘‘ British Food Fishes 
and Fisheries.”’ The science of the sea, the craft of the fishermen, the harvest 
of the sea, the value of fish as human food, the commercial aspect of the 
fishing industry, were all treated in a very practical manner by the lecturer. 
In reply to a vote of thanks for his interesting lecture, Mr. Dunlop re- 
minded the audience of the heroic part the British fishermen played in the 
Great War, chiefly in connection with the British Navy. 
The lecture was illustrated by lantern slides from the lecturer’s own 
negatives. 
On January 15th, Dr. A. R. Jackson, M.C., delivered a highly interesting 
lecture entitled ‘‘A Naturalist on the Western Front.’? Dr. Jackson saw 
active service on the Western Front as an Officer of the R.A.M.C., attached 
to the 9th Division. During his period of service he made good use of the 
opportunities afforded of personal observations in the field on the Birds, 
Fishes and Insects which occur in the area mentioned. Photography in the 
Army being vetoed, there were no lantern slides to illustrate the lecture; but 
_ the lecturer presented his hearers with a graphic word picture of his travels 
and observations. The most interesting remarks were naturally those made 
on animals which occur on the continent, but which are rare or unknown in 
Britain. Such were the Hoopoe, Grey Grey Shrike, Icterine and Marsh
