56 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



major causes, such causes to be declared justifiable by the squad physician 

 (a Springfield physician) or by a committee of the faculty. This period is to 

 begin on Wednesday, Sept. 26, 1917, and end by Christmas, 1917. 



4. Provision is to be made for the possibility of continuing the observations 

 from 2 to 3 weeks longer if necessary. As this is hkely to interfere seriously 

 with the plans of some subjects during the Christmas vacation, it is possible 

 that some way may be provided to meet the requirements of the research 

 and still allow subjects to absent themselves during the usual holiday period. 



5. The subjects will conform to the usual modes of living as regards work, 

 exercise, diet (except as restricted) and sleep. No radical change in the 

 ordinary daily life of the subject is permitted. 



6. The subject will submit to a reduction in the daily food allowance suf- 

 ficient to induce a loss of 10 per cent or more of body-weight in as short a 

 time as possible, and also to maintain this acquired reduction in weight until 

 the end of the test period. 



7. The food will be served at a table reserved for the squad of subjects in 

 Woods Hall dining room and will consist of the regular bill of fare for all 

 students of the college. 



8. It is desired that all portions of the food served be eaten completely. 

 If not, the person in charge of the serving must be notified and will make a 

 record of the food not eaten and, if necessary, collect it for analysis. It is 

 supposed that when the ration is reduced the subjects will have no difficulty 

 in eating the entire ration served. 



9. The subject will not eat or drink anything whatsoever outside of the 

 regular three meals served under supervision. 



10. Water only in reasonable quantity is allowed at any time. 



11. The subject must clearly understand that under the conditions of the 

 research, the partaking of ice cream, fruit, peanuts, popcorn, etc., as well as 

 sodas or drinks of any kind, unless intentionally served as a part of the regular 

 allowance, is absolutely prohibited. The moderate chewing of gum is not 

 prohibited. 



12. It must, however, be understood that any breaking of this most im- 

 portant rule should be promptly reported, as by so doing the seriousness of 

 the offense can be in part minimized. 



13. Collection of the urine: (a) All urine voided will be continuously collected 

 for exact periods of 24 hours each in properly labeled bottles which will be 

 provided for the purpose. (6) Each 24-hour collection will be completed 

 daily at 5^d0^ a. m. and placed at the disposal of the collector in charge 

 at the place indicated for this, (c) No urine should be lost. Accidental 

 losses must be prevented. If any occur they must be carefully noted and 

 the quantity lost reported as accurately as possible the same day. (d) The 

 loss of urine during defecation will be prevented by the simultaneous use 

 of a urine-collecting bottle, (e) If urination is to occur away from the college 

 premises the subject must take with him a bottle to receive the urine passed, 

 which is to be added to the day's collection. (/) The collection of urine at 

 the time the squad goes to Boston will not be interrupted until Sunday 

 morning. Provision for this must be made as needed. The collection of 

 urine on the Sundays in Boston will be omitted according to instructions 

 given elsewhere. 



14. Collection of feces during weekly digestion period: (a) Each Monday 

 morning at breakfast with the first mouthfuls of food eaten, two or three 

 gelatin capsules containing charcoal or carmine are to be swallowed. They 

 will Hkewise be given with the first meal on Thursday morning, (b) Collect 

 all the stools from Monday until the collector in charge will have notified
