1425 B66 1890 PREFACE IN the following pages the author has interwoven knowledge compiled from various sources with his personal official experience in both urban and rural districts. In the plan of the work and in its treatment he may perhaps claim some originality; at all events it is intended to convey the author's idea of the subjects of special knowledge necessary for those engaged in either an administrative or subordinate capacity in the Public Health Service to be acquainted with. The author has to thank Mr. Henry Law, M. Inst. C.E., for revising the statistical section and the mathematical formulæ, and for the useful tables at pages 217 and 218; to Professor Fuller the author is indebted for the scale at page 36; to Dr. Richard Budd, of Barnstaple, for the loan of original photographs and drawings; to Professor Stewart, of the Royal College of Surgeons, for facilities for copying pathological specimens in the Museum; and to Mrs. Wynter Blyth for drawing and colouring most of the lithographs. |
