and asli extracted with 1 .25 per cent sulpliuric acid and with 1.25 per cent 

 cansticpotash solution. Tbeautlior'sanswer to the above question is that 

 "except in cases where tlie difference in the feeding value of pastures 

 is very slight, the clieniical analysis of the grass by the methods here 

 employed affords fairly reliable information, and that information is 

 increased and made still more reliable by tiie analysis of the soil. 

 Further, it is probable that if we could get what might be regarded as 

 a fair saini)le of that portion of the grass which is really eaten by 

 stock, any slight discrepancies such as have been noted might disap- 

 pear. There is some additional information derivable from the sei)arate 

 estinuitioii of the protein, and perhaps also of the ash contained in that 

 portion of the grass that is solnl)le in a weak solution of acid and that 

 which is not; but it would require a larger induction than what is here 

 afforded to draw any definite conclusion regarding that point. It is 

 probable also that the separation of the carbohydrates into various 

 classes may yet provide useful information in the way of gauging the 

 feeding value of fodders.''
