II.— Experiments upon Malt and Baiji.kv. 



In 1863, at the request of the Board of Trade, experiments 

 Avere undertaken to ascertain the relative feeding value of malt 

 and of the barley from which it was made, so as to see if any- 

 thing was gained by the process of malting. It had often l)een 

 asserted, and was the opinion of many practical graziers, that 

 even if there were some loss in the process of converting barley 

 into malt, yet the superior digestibility of the malt and its 

 action upon the other items of the whole food more than 

 compensated for this loss. 



The investigation was divided into two stages— (1) an 

 encjuiry into the natiu-e and amount of the losses dming th'* 



malting process; (2) a comparison of the t 1 value ..f the 



resulting malt and of the original barley. 



Two lots of barley were selected for the .'xperinient. • a 



malting l)arley of fair (piality, the other a tiiinner, more nitro- 

 genous barley, such as would only be used for feeding. The 

 malting was done in tlie ordinaiy way, at Hertford, and .siiujples 

 of 25 lb. each were taken of the grain l.cfore steeping, when 

 thrown out after .steeping, at intervals .luring growth, and
