Mrs. Rodolph Stawell 3d3q3g

We all have our own talents, our special gifts. Sometimes these gifts seem to come to us from our forefathers, but more often it is difficult to trace their origin.

Henry Curtis 4lo5i

The capacity and aptitude for motion, observable in man, naturally lead us to an enquiry into the general principle of his corporeal functions.

Aware of the intricacy of my subject, and that the operations of the animal body necessarily embrace agents not within the range of our senses, I can..

William Harvey 1p5r3o

Harvey’s work, by which his name has been made immortal, strikingly illustrates this. He was the first to show the nature of the movements of the heart, and how the blood moved in the body.

F. H. Hall 573p5s

The flavor of good milk and cream, then, is an inherent quality due to the normal constituents of the milk; the flavors of butter, both good and bad, except that due to the fat and to odors absorbed by the milk, are held to be the result of bacterial action; the fundamental flavors of cheese are probably due to chemical decomposition, started by un..

Charles Howard Hinton 3cx6c

The fourth dimension is a subject which has had a great fascination for many teachers, and though one cannot pretend to have quite grasped Mr. Hinton’s conceptions and arguments, yet it must be itted that he reveals the elusive idea in quite a fascinating light. Quite apart from the main thesis of the book many chapters are of great independent ..
