DEFINITIONS AND TECHNICAL CONSIDERATIONS. 361 



correspond to a production of heat equivalent to a calorie, or the heat neces- 

 sary to raise the temperature of one kilo of water one degree centigrade. 



Kilometer is 0.62 of a mile. 



Lactic acid. This product is one of the vegetable acids not to be over- 

 looked in the theory of animal feeding. It is not thought to exist in any vege- 

 table product in a normal state, but is the outcome of some organic and acid 

 transformation. Beets and beet leaves contain this acid, and it is also found 

 in the cossette residuum. 



During digestion, it appears to be formed from the carbohydrates; its action 

 under these circumstances is that of effecting certain changes in the phosphoric 

 acid; it penetrates into many of the capillaries and facilitates assimilation of 

 certain nutrients. 



Legumin is a proteid compound, and may be considered as a vegetable 

 casein. 



Levulose is the sugar found in fruit; it is also called fruit sugar or 

 fructose. 



Lime must be added to fodders consisting of beet cossettes, etc. It is 

 needed for the bony tissue of the body, and is very frequently deficient in the 

 composition of most feeding stuffs. 



Lime phosphate is a substance formed by the combination of phos- 

 phoric acid and lime. 



Liter is about l.Oo quart. 



Lymph is the fluid in the lymphatic vessels, and is the filtration of the 

 liquid parts of the blood through the tissue of the capillaries. 



Lymphatic. Pertaining to the lymph. 

 Meter is about 3.3 feet. 



Methane is to be found in nature, chiefly in marshes, when decompo- 

 sition of organic substances is in progress. 



Micro- organisms are organisms of microscopic size. 

 Mucous, a term applied to tissues that secrete mucus. 



Harrow ration means that the ratio existing between the protein and 

 carbohydrates is small. An example of this is cotton-seed meal, 1:1.2, in 

 which case the protein is nearly equal to the carbohydrates. 



!Xew process linseecl meal. The process is mainly based upon a 

 naphtha-extractive mode. The meal contains from 26.5 to 40 per cent, pro- 

 tein and an average of 3 per cent. fat. It is to be noted that when its com- 

 position is compared with the old process, the oil percentage is less and the 

 protein percentage greater; hence it has of recent years found many general 

 applications. It is very discouraging for its advocates that the old linseed 

 meal appears to be more digestible than the new. This fact may be counter- 

 balanced by the difference in cost in some special cases.
