VJI. On Malting. 'By John Carr, £aj.* 



Theory of Malting. 



J- HE interior of a barley grain consists of two distinct parts, 

 a minute germ, destined to elongate into the future plant, 

 and a portion oF farinaceous and mucilaginous matter, stored 

 up expressly for its future conversion into saccharine, as the 

 pabulum of the germ in the earliest stage of it» vegetativ« 

 existence. 



The germ itself consists of two very different parts, tht 

 plumula (acrospire in malting) and the radicle or root: both 

 arc united at the same end of the grain, but in germinating, 

 the radicle very soon pi'erces the husk, and separating into 

 several fibres elongates downwards, while the acrospire, but 

 n)uch more slowly, advances through the body of the grain, 

 and piercing ihe opposite end, soon shoots up into a greea 

 blade, leaving the nusk of the corn empty, and perfectly 

 exhausted of its former contents. 



The radicle is much more rapid in its formation and 

 growth than the acrospire, because, as it is destined to pre- 

 pare and transmit to the stem nearly all its pabuia, it is ne- 

 cessary that it should be sufficiently matured to periorm this 

 office by the time the acrospire has consumed the store 

 which provident Nature had laid up for it in the grain. 



There is no difficulty in comprehending the first dawnings 

 of vegetative life in the germination of barlev ; the o-rain* 

 placed under favourable circunisiancesof moisture and warmth 

 imbibes both, and swells much ; the radicle, lying nearest 

 to the exterior, is the most susceptible of these, it swells
