I If, for example, we take from this table the formula advised for 
i the second week — i. e., fat 2.00, sugar 6.00, proteids 0.60 per cent — we 
i find such a ration furnishes a caloric value of 0.457 calories per gram. 
\ The total amount administered is 600 to 750 cubic centimeters a day, 
giving a caloric value of 274.2 to 342.75 calories per diem. Assuming 
that a healthy average child weighs 3,500 grams at the beginning of 
the second week, the energy quotient required is 100 calories per kilo- 
r gram of body weight. It will then require food supplying 350 calories 
a day properly to nourish it. 
I We see, however, that not only the lowest but the highest ration 
furnished by this table is less than its actual requirements. The 
ration is also very poor in proteid in contradistinction to mother’s 
' milk, which is normally higher in proteids during the first weeks than 
I at other periods of lactation. Of course, the theory for this modifi- 
f cation is that higher proteid would upset the digestion. This objec- 
' tion can be no longer regarded as valid. This is not, however, a very 
f serious disadvantage of this table. Under-feeding never caused seri- 
ous gastro-enteritis, and as a consequence babies fed on this plan 
I usually pass Avithout digestiA^e disturbance through the initial for- 
mulae, though they gain Aveight but slowly from them. 
j| It is when Ave turn to the percentages advised for older infants 
il Jthat the possibilities of danger are apparent. Taking the daily ration 
I advocated for the infant of 6 months, we find that the percentages of 
I this ration are as follows: Fat 4.00, sugar 7.00, proteid 2.00 per cent. 
. This gives a caloric A^alue of 741 calories per kilogram, or 0.741 calo- 
li ries per gram. The daily quantity recommended varies from 930 to 
1,500 grams, giving a total daily caloric value of 689.1 to 1,011.5 calo- 
I ries. Supposing a 6-months-old infant to have attained the weight of
