THE MUSCLE ENGINE.

WHY WE SHIVER. "Shivering is Nature's dodge to work tip temperature," said Professor Osbonie, in the course of a recent lecture on "Physiology of Exercise," at Caulfield. "When a person is contracting a cold there is always an inclination to shiver, and this is one of the most effective v:ays of increasing tlio teat of the body." The lecture dealt with muscles—their •composition, how they are fed, and their uses, "it is probable," said Pro- . fessor Osborne, "that sugar is 'broken down' and used as fuel for the muscle engine. For every 100 units of energy in the shape of sucrar about 70 per cent, is used to produce ]i«it and 30 per cent, for work. In people who do not keep themselves 'Jit' the. percentage available for work is probably lower. "The digestive organs can only work properly when the muscles of the trunk arc in good working order. Some people wonder why they find if, hard to perform an exorcise for the first time, 'fiie reason is that far too many muscles are brought into us-?. After a time only the muscles Hint avn actually needed ore used. Tiiis is Nature's ' Economy. Whey does stiffness follow an unusual exercise? There is some evidence to show that this stiffness is pnin caused by small fibres in the muscle being ruptured or torn. "Have you over wondered why the heart beats quickly when you are afraid or are facing some danger ? Here is tho reason. You must either resist and fight the danger or run auav (Laughter.) Either will mean heavy demands on the muscular system. Tli'c rapid heart-heating is N'nliirc working up the circulation of nuisciitar energy. Naturally the man who is physically fit requires less 'Hogging of, the heart' in such an emergency." Golfer on the green (after several attaints to hole the ball): "What shall I do. caddie?"
