In response to many solicitations, I have added to this edition a few
hints on teaching, deduced from physiological facts, which may prove
useful by stimulating the advance of thought in a new direction.

These hints are extracts from a series of articles on "Science and
Singing" which I had the pleasure of writing in the _Edinburgh St.
Cecilia Magazine_; and I am indebted to the Editor, Mr. A. C. Miller,
for kindly permitting me to reproduce them here.

PREFACE TO THE SECOND EDITION.

The favourable reception and rapid sale of a large first edition has
stimulated me to revise this little book, and without alteration of my
original scheme of practical utility, to somewhat enlarge on one or two
points which appeared to demand further elucidation.

In this, as in the former edition, I have received great assistance from
my friend Mr. Lennox Browne, the eminent throat surgeon, who, by ever
patiently discussing with me debatable points, and by giving me access
to cases, interesting from a physiological point of view, both at the
Central Throat and Ear Hospital, Gray's Inn Road, and in his extensive
private practice, has afforded me opportunities of increasing my
knowledge and experience which would not have arisen otherwise. I feel
it a pleasure as well as a duty publicly to acknowledge my indebtedness
to him, which I have, many times before, expressed in private.

My best thanks are also due to Mr. J. Spencer Curwen, for the help he
has rendered me in many ways.

And finally, it would indeed be ungrateful on my part, if I did not
place on record the obligation under which I consider myself to my
reviewers for the uniformly favourable notice they have so kindly taken
of my first effort, and for several useful hints of which I have duly
taken advantage.

One objection has been made which strikes at the very root of the plan
upon which I have proceeded in my little volume, and to which,
therefore, I beg leave to say a few words in reply. A learned writer in
the _Athenaeum_ finds fault with me for making use of popular instead of
scientific terms, which, he says, may be the cause to the reader of
great confusion if he refers to other works, and he adds that "Back
Ring-Pyramid Muscle" is almost as hard a mouthful as "Crico-Arytenoideus
posticus." I have asked several non-scientific friends of good general
education to read this sentence to me, and they succeeded very well with
"
