IA LUST of us know what 1t means to WI feel good" and those who do
 not certainly know what it means to feel bad" Few people, however, have any definite idea of the exact causes that produce these states of feeling. We know for instance. that a pleasant breeze on moderately warm day is likely to make us feel good. We know that a good dinner properly digested has similar effect But the exact paths by which this feeling is spread all through our organism is mys tery to most people.
 Professor George V. N. Dearborn of the Tufts College Medical and Dental Schools Boston, and the Sargent Normal School Cambridge, has made most ingenious at tempt to explain scientifically what it is that makes us feel good" and also, to some extent, what makes us feel bad"
 Among his conclusions he finds that the 100000 yilh of the intestine, little tufts, rich in smooth muscle and sympathetic nerves adapt the nutritive fats and pro teins of the blood to the immediate needs of the nerve cells and may, besides, send sympathetic influences which, fusing in the brain. make us feel good" or gen. era1ly happy.
 "Euphoria" is the pretty scientific word, that he uses for the condition of feeling generally well and happy. "Dysphoria' is the corresponding word for feeling bad.
 This scientist finds that three classes of factors principally make up the condi- tion of "Euphoria': (A) Nutritiona1 and sympathetic influences from the active in testinal villi; (B) Kinesthesia, or the sense of movement, and co the epicritic i'm pulses or the impulses which flow from sensations felt in the skin
 The nutritionaF influences toward good humor or feeling good go to the neurons or nervous units, and especially to those in the gray layer of the brain and trunk nerves through the blood streams from the liver and digestive centres. The sympa- thetic impulses that also contribute to feeling good are certain nerve currents which experimental physiology and the investigators personal experience both suggest to be in operation. These i'm pulses from the intestines have much to do with the determination of moods and passions and temperaments.
 Professor Dearborn says that under normal conditions there is a direct rela- tionship between absorption of food from the small intestines and the general state of the mind This is why acute fatigue is so immediately relieved by a glass of hot milk or matted milk or some variety of soup This profound physiological truth also explains why the worried man on coming home from the office feels his
 
 dinner. There is direct nutritive stimu- lation" of the central, and especially the cortical, nerve centres.
 "It Is not a traditional delusion," says Professor Dearborn, "that fat men and boys are usually good natured and lean women cuttingly keen and not, obviously, too happy. On the one hand, the Eskimos, and on the other hand, the races of South ern Europe, both eaters of much fat cer- tainly have higher euphoric index than the Scotchman, for example, or the thin, down-East Yankee.
 A comfortable condition of the nerve cells is dependent on the supply of "Nissl's granules," 8 complex substance com pounded of fat and protein, in which the characteristic determinant is what the biologists term lipoid a fatlike material. or phosphorized fat. Experiments have shown that there is very quick loss of this material in the nerve cells when the loss of material by the body exceeds the intake In addition to these important bodies the sheath of the principal nerves is fatty substance, very liable to suffer from the same causes
 The minute nerve cells are in imme- diate and constant relation with the blood stream. A blood corpuscle passes entirely
