EXPERIMENTS IN
 DIET AT YALE Professor Fisher Proves Sue cess of Thorough
 Mastication.
STUDENTS MAKE TRIALS
Large Decrease in Meat Con- sumption Result of

and Professor Chittenden of Yale uni-
 verslty, in regard to the effectiveness
 of thorough mastication of food in re- Istoring perverted appetite to normal
 instincts, are corroborated by Profess
 sor Irving Fisher of Yale university in
 the report just issued describing one of series of experiments he is con- lducting. This report of Professor
 Fishers shows that nine healthy Yale students who participated in the ex-
 pertinent doubled their working power physically and increased their mental
 capacity by strict attention to thor tough mastication of food and obedi- lence to the dictates of appetite. Under the chewing regime the appetite grad Iually called for less and less meat
 and other high-proteid foods.
 The report of another experiment, (which was with forty-nlne flesh eaters
 and flesh-abstainers, has already been
 made public, and showed that those
 who either abstalned from meat alto
 gether or ate it sparingly had greater endurance than those who ate meat i in the ordinary quantities.
 Professor Fisher is an economist and
 not Q physlologist, and is making these studies solely to get at the pric-
 tical truth as to what the factors are
 which induce fatigue, for it is fatigue which sets the limit to the days out put of man.
 Professor Fisher is still engaged in ! his Investigations, and other reports
 are to follow
 The report is issued of one of the l diet experiments in the series which
 Professor Irving Fisher of Yale uni-
 versity is conducting. This report shows that the nine healthy Yale stud ents who participated in the experi- ment, by following the rules of thor
 ough mastication and strict obedience to taste-instinct, gradually reached of
 their own accord and almost uneon-
 sciously large reduction In their con
 sumption of meat. Their appetite no longer seemed to require it. The ul- innate result was that their working power, both physical and mental, be-
 came tremendously increased as prov
 en by tests taken at the beginning, in
 the middle and at the end of the ex-
 pertinent Professor Fishers conclu- sons are to the effect that thorough
 mastication restored normal appetite instincts, and that these are our best guides to the proper amount and kinds of food to be used. --@
 Another experiment, the report of
 which has already been issued, was with forty-nine fesh-eaters and flesh- abstainers. This report showed marked superiority in muscular ehdur- ance of the fiesh-abstainers over the fesh-eaters. The superiority Professor Fisher ascribed not strictly to the ab- stentlon from meat but to the use of a How proteid dieth This he explain- ed might be maintained without be- coming vegetarian, although the amount of neat-eating must be great ly reduced. Professor Fisher is still engaged in his Investigations and oth- CT reports are to follow. Thus far his reports corroborate the claims of Mir. Horace Fletcher and Professor Ghittenden of Yale university as to the effectiveness of thorough mastlca- ton in restoring perverted appetite to normal instincts.
 That the basis of physical and men, tai efficiency is largely matter of | physiology, and that most physiologi- | cal evils are due to diet has been so strongly impressed on Professor Irv- ing Fisher, professor of political econ | omy at Yale university in his studies of economic ondltions-labor, etc. that he has undertaken a series of diet | experiments, the report of one of | which is just issued by the Connecti- cut Academy of Arts and Sciences.
 Professor Fisher does not pretend to | be physiologist and has no pet the ories to prove, but has undertaken the experiment solely to get at the prac- tical truth as to what the fatcors are which induce fatigue, for it Is fatigue which sets the limit to the days out put of man.
 Professor Fisher seems to show in this report that one of the principal causes of excessive fatigue is hurry at meals, which induces the excessive use of high-proteid foods (that Is, meats, I fish, eggs and other hearty foods) li which are stimulating in their effects. This stimulation the stomach craves when food is not properly prepared for { t by thorough mastication. If exces- tive use of high-proteid foods is the primary cause of early fatigue, while It the same time the high price of Ei hese very articles of food helps hold he laboring man in poverty, the im- lC of this discovery to the lab- N ,ring man is immeasurable It would 'eem, from the report of Professor Fishers investigation, that under nor nal physiological conditions the lab ( ,ring man should not experience at the h md of the ordinary days labor such 1 atigue as would hinder his spending l ome time in improving himself and in ( rying to lift himself in the economic { cale.
 This investigation is one of series f If studies into the factors which make l or efficiency. The report of another ! experiment. has already been made Z public. This showed from tests of a lumber of flesh-eaters and flesh-ab- tainers Cor comparative flesh-abstain- { rs) that the abstainers had sometimes 1 Iouble the working endurance of the {
 Thus far Professor Fishers investi- i ;ations show, first that insufficient $ hewing of food induces excessive use 7 f high-proteid, and, second, that the I se of high-proteid induces early II atigue. His reports corroborate the f
