Yorkshire Geologists at Hull. 
clays of Mr. Clement Reid had about 80 per cent, of their pebbles of York- 
shire Carboniferous rocks or Norwegian rocks. The Hessle clays included 
large quantities of Cheviot and South Scottish rocks. 
Professor Kendall, commenting upon the high significance and im- 
portance of the observations of Mr. George Sheppard and Mr. Stather, said 
that the work done by amateurs in science in England was the wonder of 
the Germans. Our friends the enemy never could understand how it was 
when they met a party of geologists in the field they were usually 
amateurs, with perhaps not a professor among them. Though, added the 
speaker, there are some professors who are amateurs too in the literal 
sense of the word. 
Miss M. A. Johnstone, B.Sc. (of Manchester and late of Bradford) 
read some notes on an interesting calamite which she had collected in a 
clay-pit in Bradford. This threw much light on the growth of that plant. 
Mr. John Holmes (Cross Hills) showed some lantern pictures of the 
stone quarries in the mill-stone grit about Keighley, and indicated the 
problems raised. A discussion followed, which was taken part in by 
Mr. A. Gilligan, (Leeds University). 
Mr. J. J. Burton gave a lantern lecture on coast erosion in Yorkshire, 
in which he illustrated the various ways in which the cliffs are being worn 
away, especially where the rocks are of a soft nature. 
Air. \Y. R. Barker (Barnsley), described the ‘ Fossil Plants of the 
Coal Measures,’ principally in the Barnsley area, and illustrated by 
lantern slides the remarkable structures of these ancient floras. 
Mr. H. Hamshaw Thomas submitted a paper on ‘ The Thinnfeldia 
Leaf- bed of Roseberrv Topping,’ where a recent important discovery has 
been made, showing plant remains in an extraordinarily complete state of 
preservation. Mounted preparations of these were exhibited and kindly 
presented by Mr. Thomas to the museum. This paper will appear in 
extenso in The Naturalist. 
Mr. T. Stainforth gave suggestions for ‘ A Central Collection of In- 
dicator Boulders.’ 
Mr. C. Bradshaw, of the Sheffield Museum, exhibited some interesting 
geological specimens recently added to that institution. 
Mr. H. C. Drake contributed a paper on some ammonites from a rock 
known as Cornbrash, which is so well developed in Peacock’s quarry near 
Scarborough. 
Mr. C. Thompson, of Hymers College, exhibited some of the more 
interesting ammonites from the Yorkshire glacial beds. 
Mr. T. Sheppard handed round the publications of Mr. William Smith, 
the father of English geology, a set of which he has in his possession.

Plant Life in the British Isles. By A. R. Horwood, Yol. II. London : 
Churchill, 1914, pp. 14 + 358, 6s. 6d. net. In the second volume of this 
work, which deals with selected types from the different natural orders 
of British plants, the author continues the introductory matter from vol. 
I., and deals brieflv with the cell and tissues, the organs and their work, 
absorption, transpiration, respiration, photo-synthesis and transport of 
materials. In covering a wide field in short space, the author has allowed 
numerous errors to creep in, e.g., on p. 10 he says : 1 In the cuticle of 
leaves are the stomata,’ on the next page he speaks of ‘ the upward trans- 
port of starch ’ ; we are told (p. 76), that in the Barberry ‘ there are long 
shoots with the leaves forming groups of spines owing to arrest of the 
branches.’ Figure 3 of a ringed stem is likely to mislead and the descrip- 
tion of it on p. 37 does not clear up the difficulty. Much interesting in- 
formation is given in the description of the types which will prove helpful 
to many who wish to widen their knowledge of the common plants around 
them. The usefulness of the volume is enhanced by 71 photographs of 
the types dealt with, and there are also 7 clearly drawn diagrams.
