Sir CHARLES LOCOCK, Bart., F.R.S.,

FIRST PHYSICIAN-ACCOUCHEUR TO HER MAJESTY THE QUEEN.

Dear Sir Charles:

Your kind and flattering approval of this little Book, and your valuable suggestions for its improvement, demand my warmest gratitude and acknowledgments, and have stimulated me to renewed exertions to make it still more complete and useful, and thus more worthy of your approbation.

You have greatly added to my obligation, by allowing me to indicate those passages of the work that you considered required correction, addition, and improvement. On reference to these pages, it will be at once perceived how greatly I am indebted to you, and how much I have profited by your valuable advice.

I have the honor to remain,

Dear Sir Charles,

Your faithful and obliged servant,

PYE HENRY CHAVASSE.

Priory House, Old Square,
