PREFATORY NOTE
IN putting this first edition into the hands of the
student, I desire to emphasise two facts. First,
that the collection is very far from being exhaustive,
although it is hoped that in due time it may he fairly
representative of the building stones of the world.
Secondly, that the descriptive notes, which precede the
catalogue, do not in any degree aspire to the character
of a geological exposition: they are only an attempt to
weave together a few facts, which may he useful to
the student.
I am greatly indebted to Professor Hughes and his
colleagues, indeed to all who are officially connected
with the Sedgwick Museum, for their unfailing kind­
ness, and the friendly assistance they have at all times
afforded me. Special thanks are due to Mr A. Harker
in undertaking to be responsible for the penological
designation which appears on the labels of the Igneous
rocks.
I wish to express my acknowledgments to Professor
Grenville A. J. Cole of Dublin for the kind help he has
given me whilst collecting specimens to illustrate the
building stones of Ireland; and to Dr G. P. Merrill of
thej United! States National Museum at Washington,
for his advice and ready assistance in my endeavour to
form a representative collection of specimens from the
United States.
vi PREFATORY NOTE
Lastly, I desire to record my deep sense of gratitude
to Professor T. G. Bonney, who has kindly revised my
manuscripts. I need hardly add that his revision has
attached a scientific value to the contents of this publi­
cation which otherwise it would not have possessed.
Through the courtesy of the Woodwardian Pro­
fessor, sufficient space has been allocated in the museum
for this collection*, and ample room still remains for
additions to it. It is therefore hoped that whenever
students and others find that they can contribute
fresh examples, they will avail themselves of the
opportunity. By following this suggestion, the donors
will have the satisfaction of knowing that not only are
they enhancing the value of the collection for educa­
tional purposes, but also that their names will be
enrolled among the many benefactors of the ancient
and renowned University of Cambridge.

INTRODUCTION
Specimens of Building Stones brought together to
form a collection are usually arranged according to
their lithological character irrespective of their age.
Possibly this method may have been found to be
the most convenient for architects and builders, other­
wise it would not have been so generally adopted.
Bearing in mind however that the present collection
is primarily for the use of students of geology at
Cambridge University, it has been thought that the
specimens will be more helpful to them, if they are
arranged in stratigraphical order, hence this method
has been adopted, except in the case of the igneous
rocks.
For convenience of reference, the examples repre­
senting the building stones of the British Isles have
been arranged separate from those obtained from the
Colonies and from foreign countries.
The specimens are chiefly in the form of 4^-inch
cubes, the sides of which are dressed in the usual style
adopted for the purposes for which the stone is
generally used in the region from which the specimen
comes. One face of the cube is polished, when it admits
of this treatment, and another side is usually left
rough, in order that the grain and texture of the rock
may be clearly seen.
A label is affixed to the front of each specimen,
bearing the following particulars:—
1. The name by which the stone is best known in
commerce.
