and Smith. The first three were taken at Delamere; WV. zonaria ochracea at 
Wallasey. We are indebted to Mr. S. Gordon Smith for the loan of the block, 
which was used in illustration of the article quoted above; and tender our 
congratulations to the authors on the discovery of these remarkable and 
interesting additions to the fauna of the district. 
GEOLOGICAL SECTION. 
During the past session three successful Sectional Meetings were held. On 
October 23rd, Mr. T. W. F. Parkinson, M.Sc., F.G.S., of Manchester, lec- 
tured on “‘ Development of the River Systems of England and Wales.” Mr. 
Sneyd Kynnersley, on January 23rd, at short notice, lectured on ‘“‘ The 
Danube,” and the large audience assembled to hear the advertised lecturer, 
who was prevented from fulfilling his engagement, was more than satisfied 
with the substituted lecture. Professor P. G. H. Boswell gave an illuminating 
lecture on February 19th on ‘“‘The Discovery and Exploitation of Mineral 
Oils,” and in his concluding remarks warmly advocated closer relationship 
between the Universities and Societies such as the Chester Natural Science 
Society. At the same time he laid particular emphasis on the practical side 
of the study of Geology. 
The Geological Section has suffered a heavy loss by the death of its 
Chairman, Mr. A. W. Lucas. Mr. Lucas was devoted to the work of the 
Society, with which he had a long and useful connection, As early as 1876 
he became a member, was appointed Secretary of the Geological Section in 
1887, and elected Chairman in 1898. His first lecture to the Section in 1887 
was on ‘‘ The Origin and Age of the World in which we live,” his last in 
1918 on ‘‘ Coast Erosion in North Wales.’’ In 1908 he was presented with 
the Kingsley Memorial Medal. His interest in the section was maintained 
to the last, and his parting gift of the ‘‘ Lucas Collection of Fossils ’’ bears 
witness to this. The arranging and classification of this collection—unfinished 
through his death—was his last work in connection with the Society. On 
excursions, and in the conduct of Field Meetings, his kind, patient, and clear 
explanations were freely given, and much appreciated. To his single-minded 
devotion, disinterested attachment, and faithful labours, the Section acknow- 
ledges its great indebtedness. Such men as he have given to the Society 
whatever of value it possesses. 
MICROSCOPICAL SECTION. 
One meeting only has been held during the past Session, on Thursday, 
27th November, 1919, when a microscopical demonstration was given, Dr. J. 
Elliott, J.P., presiding. The members who exhibited were Mr. J. Davies, 
Mr. J. Lyon Denson, Dr. Elliott, Mr. A. E. Goodman, Prof. R. Newstead, 
Mr. A. Newstead, and Dr. Lawson Russell, who also gave brief 
descriptions of the object each displayed. 
The Chairman intimated at the commencement of the meeting that Mr. 
Michael Johnson, who had been Secretary for a number of years, felt com- 
pelled, owing to continued ill-health, to resign the position, and after express- 
ing the profound regret which all the members felt, and the sympathy they 
had for Mr. Johnson, nominated Mr. A. E. Goodman, F.L.S., as Secretary. 
This was seconded by Prof. R. Newstead and unanimously carried, the selec- 
tion being endorsed by the General Committee, in accordance with rule, at 
their next meeting. 
NATURAL PHILOSOPHY SECTION. 
Under the auspices of this Section, a lecture was delivered by Mr. H. 
Morrell, B.Se., on ‘‘ Combustion.” The lecturer dealt first with the various 
theories -of combustion which have at various times held the field, and in- 
dicated how the phlogistic theory was ultimately defeated, despite the fact
