Hills' fed Nutriotone to seven cows in accordance with instruc- 

 tions of the circular. He states " the material does not appear to 

 have increased productiveness in this particular experiment." 



Bartlett" made a similar trial of the value Nutriotone using five 

 Jersey cows. He states that " Nutriotone was taken in preference 

 to any other compound, not because it is believed to be any better 

 or worse than any other of a like nature, but for the reason that it is 

 being extensively advertised and persistently sold by the Company's 

 agents not only as a curative agent, but as a stimulant of the produc- 

 tion of flesh and milk." His conclusion is as follows : " In neither 

 of these cases did Nutriotone seem to have any effect favorable or 

 unfavorable. The slightly smaller fiow 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." 



Brooks^ fed Sheridan's condition powders to poultry in three 

 experiments and states that he obtained no noticeable increase in egg 

 production and that the powders did not pay for their use. 



Sir John Lawes* instituted experiments with a condimental food 

 using six pigs and twenty sheep to determine its effect on growth 

 and fattening. He concludes the description of his experiments as 

 follows : 



"It is clear that nothing was gained by adding to the barley-meal 

 and bran, one-fifth of its weight of food, costing about five times as 

 much money. The results previously published of experiments with 

 pigs, taken together with those now recorded in regard to sheep, 

 seem sufficiently conclusi^'e against the assumption that the tise of the so- 

 called condijnents increases the assimilation of food, I'V fattening animals 

 in a state of health. They are equally conclusive on the subject of the 

 profit or loss to the feeder from the use of such substauces. In conclu- 

 sion, I feel bound to say, that I should require much clearer evidence 

 than any that has hitherto been adduced, to satisfy me that the balance- 

 sheet of my farfn would present a more satisfactory result at the end of 

 the year, were I to give each horse, ox, sheep, and pig, a daily alloiv- 

 a nee of one of these costly foods.'''
