The gradual shrinkage in these experiments is due to 

 advance in period of lactation. In neither of these cases did 

 nutriotone seem to have any effect, favorable or unfavorable. 

 The slightly smaller milk flow with nutriotone does not mean 

 anything in particular except to add increased emphasis to the 

 falseness of the claim that two large tablespoonfuls fed with each 

 feed "will produce a great increase of much richer milk." Of 

 course the money spent for nutriotone in other cases was a dead 

 loss. While there may be instances in which the purchase of 

 a condimental food is financially profitable, it is significant that 

 no exact experiments, conducted by disinterested parties, have 

 shown a return equal to the cost
