A Memorandum on the Dietaries of Labouring Prisoners in Indian Jails. By Dr. T. R. 



Lewis. 188L 



Chapter I. — A brief Sketch of some recent Regcarchc-s heari/i// on tlie Question of Lalionrincj 

 Dietaries. — A knowledge of the general principles of dietetics essential to a correct appreciation of 

 the comparative nutritive value of dietaries — The organised and unorganised forms of food — The 

 principal sub-divisions of organised alimentary substances — The computations of the nutritive 

 value of the dietaries in the text and in the appended tables — The chief functions of the nitro- 

 genous and carbonaceous principles of food : Liebig's doctrine — Every-day experience in this 

 country adverse to the doctrine that nitrogenous aliments are the chief sustainers of mechanical 

 effort — This experience is in accord with the teaching of modern physiology. Not expedient 

 therefore to continue formulating dietaries on the basis of a doctrine which is no longer tenable —  

 Present tendency is to invert Liebig's doctrine, mechanical effort being declared to be due to the 

 combustion of carbonaceous and not of nitrogenous material — Extent of the •'instinctive inclina- 

 tion " for an extra supply of albuminoid food after exertion dependent in a great measure on habits, 

 etc., of individuals and races — Opinions as to food-requirements of Native prisoners are often based 

 on the results of specially devised exi)eriments on Europeans accustomed to animal food and in 

 fairly easy circumstances 641 — 645 



Chapter II. — Moleschott's " Standard-diet." Edward Smith's English In-door Lahourers' 

 Dietaries, and tlie Lahmirinfj Diet Scales of English Prisons. — Moleschott's '•standard-diet" for 

 Europeans on ordinary labour — The dietary of the poorer class of in-door labourers in England 

 much lower than Moleschott's standard — As also the diets of laboui-ing prisoners in England — The 

 diet scales for local prisons in England and Wales submitted to Parliament in 1878 — The diets of 

 labouring prisoners in English local prisons — The nutritive value of this dietary — Reports of the 

 Commissioners of Prisons on this dietary, highly favourable — The diets of convict prisons in 

 England — Their nutritive value — Eemarks of the Royal Commissioners of 1878-79 on this diet 646 — 652 



Chapter III. — Tlte Adaptation of the Diet Scales of Lahouring Prisoners in England to Indian 

 Bequirements. — Desirability of taking such approved dietaries as the bases for the construction of 

 diet scales for Indian jails — What can be regarded as " sufficiency" in a prison-diet — Of the two 

 English prison-dietaries the local prison scales appear to be the most suitable for native prisoners 

 — Weight of individuals as a guide for estimating food-requirements— The English local prison 

 dietaries apportioned to the average relative weight of native prisoners 652 — 654 



Chapter IV. — The NutritiveValne of tlie Diet Scales of Lahoimiig Prisoners at present or recentlg 

 in force in Indian Jails. — The scales of dietary for labouring prisoners at present in force in India 

 — Computations of their nutritive value — The nutritive value of a diet depends on its digestibility 

 as well as on its chemical composition— The nutritive value of rice — The proportion of nitrogen 

 and carbon in Indian cereals and pulses — Dr. Mouat's diet-scales approved by the Indian Jail 

 Committee of 1864 — Animal food a compulsory ingredient — A detailed ace ount of these diets — Dr. 

 Mouat's scale for Bengalis should, on the English local prison standard, suffice for men weighing 

 110 lbs. — Dietary for labouring prisoners proposed by the Indian Jail Conference of 1877— Animal 

 food recommended to be an optional ingredient in diets for labouring prisoners — Ambiguities in
