Hills* fed Nutriotone to seven cows in accordance 

 What experi- with the instructions of the circular. He states 

 ments have " the material does not appear to have increased 

 taught. productiveness in this particular experiment." 



Bartlettf made a similar trial of the value of Nutri- 

 otone 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 Com- 

 pany's agents not only as a curative agent, but as a stimulant of the 

 production of flesh and milk." 



His conclusion is as follows: " In neither of these cases did nutri- 

 otone seem to have any effect favorable or unfavorable. The slightly 

 smaller 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 ' ". 



Brookst 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 Lawesll 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 exper- 

 iments with pigs, taken together with those now recorded in regard 

 to sheep, seem sufficiently conclusive against the assumption that the 

 use of the so-called condiments increases the assimilation of food,, 

 by fattening animals in a state of health. They are equally conclu- 

 sive on the subject of the profit or loss to the feeder from the use of 

 such substances." "In conclusion, 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 farm would pre- 

 sent a more satisfactory result at the end of the year, were I to give 

 each horse, ox, sheep, and pig, a daily allowance of one of these 

 costly foods."
