IN the present volume I have endeavoured to explain, in simple language, some difficult problems in “Animal Mechanics.” In order to avoid elaborate descriptions, I have introduced a large number of original Drawings and Diagrams, copied for the most part from my Papers and Memoirs “On Flight,” and other forms of “Animal Progression.” I have drawn from the same sources many of the facts to be found in the present work. My best thanks are due to Mr. W. Ballingall, of Edinburgh, for the highly artistic and effective manner in which he has engraved the several subjects. The figures, I am happy to state, have in no way deteriorated in his hands.

Flight the poetry of motion, . - - - Flight a more unstable movement than that of walking and swimming; the travelling surfaces and movements of animals adapted to the earth, the water, and the air, • The earth, the water, and the air furnish the fulcra for the levers
formed by the travelling surfaces of animals, • • Weight plays an important part in walking, swimming, and flying, - •
The extremities of animals in walking act as pendulums, and
The body and wing reciprocate in flight; the body rising when
