If we wished to give them the same proportion in white turnips and 

 oat-straw, we must supply for every 2 nutritious equivalents of the for- 

 mer, 1 nutritious equivalent of the latter; for this mixture gives the 

 proportion of 1 to 8-4; that is, they must he fed with 130 lbs. of fresh 

 white turnips for every 55 55 lbs. of dried oat-straw. 



A horse that works hard requires the proportion of 1 to 4. For this 

 we give him oats which represent that proportion. But if we wished 

 to give him the same proportion in field beans and hay, we must take 

 for every 2 alimentary equivalents of the former 1 alimentary equiva- 

 lent of hay, for such a mixture has the proportion of 1 to 4*1. We 



feed him therefore with 8*58 lbs. of dry field beans for every 12*47 lbs. 

 of dry hay. 



A man requires for a certain mode of life the proportion of 1 to 3. 

 He wishes to eat beef and potatoes; he must, therefore, for every 2 

 alimentary equivalents of beef eat 1 alimentary equivalent of potatoes, 

 for this mixture gives the proportion of 1 to 3*01 ; he must therefore 

 use for every 2 lbs. of boiled beef (reckoned without water) 41 lbs. of 

 potatoes (reckoned in the fresh state.) 



If he wished to produce the proportion of 1 to 4 with carrots and 



raw bacon, he will attain it by mixing 5 alimentary equivalents of the 



former with 6 alimentary equivalents of the latter, which represent the 



proportion of 1 to 399. For this purpose he must eat 338 parts of 



fresh carrots for every 11 parts of raw bacon (reckoned free from 

 water.) 



Concerning the question, as to what is the proper quantity of aliment 

 (possessing the due proportions) which is to be given under different 

 circumstances, experience alone can determine it. For the computa- 

 tion, how the necessary quantity may be given in the diverse properly 

 assorted alimentary mixtures, we would refer to the divisions III, IV, 

 V, and VI, of the foregoing table. 



If a cow requires in twenty-four hours 10 kilogrammes (22*05 lbs. 

 avoirdupois) of air-dried hay, how many kilogrammes of the mixture 

 given above of clover and potatoes would it require to replace it ? 



10 kilogrammes of air-dried clover contain in all 8*04 kilogrammes 

 (17*728 lbs. avoirdupois) of nutritious matter, for 



12*47: 10 03=10:07 



x= 8*04. 

 That mixture will consist of 9*7 kilogrammes (21*38 lbs. avoirdupois) 

 of dry clover, which contain in all 7*68 kilogrammes (1693 lbs.) of 

 nutritious matter and 123*6 kilogrammes (272 5 lbs.) of potatoes, which 

 contain in all 31*20 kilogrammes (68*79 lbs.) of nutritious matter. 



133*3 kilogrammes (293*93 lbs.) of the mixture contain accordingly 

 38-88 kilogrammes (8572 lbs.) of nutritious matter. 



38*88 kilogrammes (85*72 lbs.) of the joint nutritious matters are 

 equal to 133-3 kilogrammes (293*93 lbs.) of the mixture. How many 

 are 8-04 equal to ?° cs=97* (60*63 lbs.) 



27*5 kilogrammes (6063 lbs.) of the mixture in question are equiva- 

 lent to 10 kilogrammes (2205 lbs.) of hay in the proportion and quan- 

 tity of nitrogenous and non-nitrogenous alimentary substances. In a 

 precisely similar manner the kind and quantity of the salts must be at- 

 tended to in practice.
