CHAPTER X. 



CASEIN FOODSTUFFS. 



IT is a well-known fact that animal albumen plays a very 

 important part in the food of man ; and it may also be 

 accepted as proved that man should take one-third of his 

 requirements of albuminoids in the form of animal food. In 

 this connection, meat is the principal and almost sole form 

 of nourishment possible, since eggs, milk and milk products 

 cannot have the same importance for dwellers in towns, 

 soldiers and sailors, hospital patients, prisoners, and so forth, 

 as they have for country people. Besides, meat is the only 

 form of animal food that man can continue to take with 

 pleasure in sufficient quantity to satisfy the demands of the 

 body for albumen ; whereas, in the case of milk, the con- 

 sumption of the necessary quantity sooner or later causes a 

 distaste for the article with most people. Now, in order to 

 provide meat supplies at a price which would enable the 

 bulk of the populace to purchase a sufficiency for the pur- 

 poses aforesaid, it is not enough to merely have recourse to 

 cheap imported meat. On the one hand, there is the diffi- 

 culty of excluding disease, and, on the other, the alterations 

 to which the meat is exposed (drying, pickling, smoking, etc.) 

 in order to make it keep, frequently affect its flavour and 

 digestibility. 



For this reason, said Dr. Adolf Jolles, in a paper read 

 before the Industrial Association of Lower Austria, it is 

 easy to understand that the endeavours of modern chemistry
