The Motion of Animals.

. [Two lectures were lately S delivered. before the Birmingham t Natural Society, :ljy Professor Muybridge* of the Petvnftyl?vania University, on the subject; :ot- the motion of animals, rh revehled- by jhstan-. taneoua photographs, shown by the limelight. It appears thiit tlie'miiveisity.iits spent £8000 in forming this series/of photographs, the originof which , was the oft-debated question whether an American trotting horse is .ever entirely roffr tie ground when moving at full pace.- -^ Some of these photographs are taken in one four-thousandth part of a Hccond, and a series of them, is. over the length of'a'horse's'stride, so that they giy c, r the \ c^nsecutiv^ , ; as»uu»ed by.f.the.'aTiJ^iars^leg^ from.the beginning, ofjtlie.pace to the^'endi • < Itittishopni, for, ; instance,, .that" (! a jgalloping horse rests hip'weight,,upon his forefeet for, a longer period than upon his hind-feet, and that in, the \ case cjf aj thoroughbred < the stride of the fore-)ea^, 'alone may extend over a length ,e^ual\tb f the' height oi-the 'horse's"""withers from,the ground. 'This shows that, although, it is the common supposition, jthat.the hindrlegs do tho greater part of the running, it. is-really the fore-legs.that perform the major part of the work ; arid we can thus account for the well-known.-bjijt hitherto inexplicable fact,,that' a facer's, .forelegs , invariably break riown'first. Mr Muybridge also demonstrated how ,it is that a dog could outrun a-horse, and"> showed how it was conceivable tliat by,.training,a L horse to use h\» .leg's tli'e, same order,'in which a dog uses his the'speed of the horse might be-enoruiQusly..increased. ■ < t ,;, ;.■■)•, f %^y-^%
