The Engines of the Human Body - Being the Substance of Christmas Lectures Given at the Royal Institution of Great Britain, Christmas 1916-1917 #265255

I therefore introduce the reader to the human body in its entirety - as a complete, living, and moving machine. In all of these three respects, I believe, this work differs from its numerous predecessors.<br><br>While I have made my main appeal to the general reader - to the man or woman who desires to know what modern medical teachers think of the marvellous contrivances of the human machine, - I hope that the account here given of the human body may also appeal to medical men and to professional engineers.<br><br>I hope, too, that students of Medicine and of Biology, as well as lecturers and teachers who have to impart an elementary knowledge of human Physiology, may also find assistance and guidance from its pages.<br><br>I am glad to have this opportunity of thanking Sir James Dewar of the Royal Institution for much helpful counsel, and of acknowledging my indebtedness to Sir Thomas Wrightson, Bart., M.Inst.C.E., and to Mr Allan A. C. Swinton, F.R.S., M.Inst.C.E., for reading over the proof-sheets of those chapters which deal with mechanical and electrical contrivances.
