(probably Carboniferous Limestone stained with haematite) 

 which has clearly been crushed out and the fragments partly 

 separated by the southward movement of the ice (Fig-. 2). Above 

 the layer of stones is a finely laminated stoneless clay, about two 

 feet in thickness {c, Fig. i), which is a fairly constant feature in 

 the Holderness cliff sections. The gravel next above \.\{\?>{d, 

 Fig. i) is very fine, the largest pebbles being 3 or 4 inches in 

 diameter, whilst they average i or ij inches in diameter. They 

 are generally waterworn, but there are a few sub-angular.

Mixed with the gravel is a large quantity of sand with a few 

 thin layers of clay. The upper five feet of the cliffs consists of 

 Hessle boulder-clay of the usual foxey-red colour, though it is 

 here much broken and weathered {e, Fig. i). It contains only 

 a few small stones, amongst which are two hard sandstones 

 (Carboniferous) and a fragment of Cheviot porphyrite. 



x\s this interesting section will probably disappear in the 

 coming winter it is as well to have it recorded. I am indebted 

 to Mr. B. Woolass for the photograph on page 301.

Thoug-h this is essentially a handbook for students, and unques- 

 tionably a perfect work of its kind,- it also particularly appeals to the 

 naturalist. By the aid of this book it is an easy matter, without any 

 technical knowledg^e, to understand the principal features in connection 

 with the natural history of man — a species far too frequently neglected by 

 naturalists who may be fairlv familiar with other members of the animal 

 kingdom. It is perhaps difficult to select the chapters most likel_v to 

 interest the readers of this journal, but those which appeal to the writer 

 particularly are 'Human Embrvology, ' 'Comparative Craniolog^y and 

 Craniometry,' and 'Comparative Osteology.' In these chapters the respec- 

 tive subjects are dealt with with unusual clearness and precision. An 

 important feature in the book is the great number of illustrations (over 330), 

 which principally consist of the author's own sketches illustrating- the points 

 he describes. 



Mr. Charles Bailey has favoured us with a reprint of his paper on 

 ' Sisyvibriiiin stricfissimtim Linn., at Heaton jMersey, for the last fifteen 

 years ( 1890- 1904).'
