| (eiissites years ago Professor Phillips published a neat little 
volume, small enough to go into a schoolboy’s pocket, for it 
contained only 189 duodecimo pages and two outline diagrammatic 
plates. Yet it professed to be a ‘Guide to Geology,’ and dealt, in 
that small space, with the great problems of the mineral composition 
of the globe, its temperature, physical geography, the arrangement 
and origin of rock-masses, and the distribution of life; and gave a 
description of all the formations which aqueous and igneous forces 
have manufactured or moulded into shape. The author was not yet 
a Professor, but he was Secretary of the British Association, and a 
Fellow of the Royal Society. His love of tables and calculations 
was shown as strongly in this early performance as in all his subse- 
quent writings; and the methodical division of his subject might 
have served as a model for his competitors. Each series of strata 
had a separate heading for its thickness, mineral character, stratifi- 
cation, cleavage, sub-divisions, physical geography and topography, 
organic remains, and bibliography. 
In 1838 a third edition of the ‘Guide’ appeared, with 186 pages 
of letter-press and four plates, the frontispiece being an admirable 
little bird’s-eye-view of the Isle of Wight; and the small geological 
map of England was now shaded with engraved lines, to show the 
extent of the principal strata. These editions were dedicated to the 
Yorkshire Philosophie Society; those which succeeded are inscribed 
to the University of Oxford. 
In the edition of 1854 the text was increased to 211 pp., and the 
little map of England converted into a yet smaller map of the British 
Isles. And in the new version, which has just appeared, there are 
314 pages; the little geological sections are remodelled, though 
essentially the same as before, and 53 woodcuts, or ‘diagrams,’ are 
added to the text. Although thus grown to more than twice its 
original bulk, Professor Phillips’ ‘Guide’ is still the most portable 
of text-books; and it has this great and distinctive recommendation 
—that it is the work of one who has himself seen and understood the 
things about which he writes ; and, when we remember that there 
are eminent professional geologists who are neither engineers, 
mathematicians, chemists, mineralogists, nor paleontologists, we 
cannot sufficiently admire the amount of severe study and self- 
discipline implied in every aspect of Professor Phillips’ ‘many-sided’ 
mind.
