nature, using for its text the rocks and stones of the neigh- 
borhood of Philadelphia, on both sides of the Delaware. 
It leads the reader by a series of excursions to points of special 
interest in connection with geological inquiry, and directs him 
how to observe, and what to observe. 
Ue above work is intended as an introduction to the study of 
“ Professor Heilprin’s explanations of principles are so clear, 
and his methods of investigation so admirable, that a careful 
perusal of his book ought to give the would-be student all the 
cues he may need for an intelligent study of the geology of his 
neighborhood, no matter where it may be.’’—Philadelphia Even- 
ing Telegraph. 
“His delightful book subordinates the dry scientific to the 
picturesque and poetic. There is no gentleman or lady dwelling 
anywhere near Philadelphia, on either side of the Delaware, who, 
if endowed with any taste for the work of creation, will not enjoy 
this curious monograph.’’— Philadelphia Evening Bulletin. 
‘‘ Professor Heilprin adopts that happy style of presenting the 
scientific facts with which he is familiar which Hugh Miller and 
Huxley and Tyndall, and many others, have done much to 
associate both with sound and with unsound science.’’—Journal 
Franklin Institute. 
‘‘The present volume is an admirable exemplification of the 
true method of geological study. . . . The work is admirably 
done, and the studious citizens of the Quaker metropolis owe 
their best thanks to the young geologist who has performed the 
task.’”’— Popular Science Monthly.
