FARINAS AND FECULAS. 



FARINAS. 



Fine wheat flour, Ador, Farina, F. tritici. The finest flour 

 obtained by sifting the meal produced in the first grinding of 

 wheat between sharp stones by a sieve of 64 wires to the incli ; 

 used for pastry. — Middlinr/s. The remainder of the flour of the 

 first grinding that will pass through a coarser sieve ; used for 

 making household bread, but is mostly reground. — Seconds. The 

 finest part of the flour, obtained by grmding middlings over again, 

 between blunt stones ; used for making bakers' fine wheaten bread. 

 — Pollard. The coarse flour, from whence the seconds has been 

 sifted : used for making sea biscuits and gingerbread, and to fat- 

 ten poultry and hogs. According to Accum, S2 pecks of wheat 

 in the London mills yield 88' of flour, 8 of pollard, and 12 of 

 bran ; the bulk of the wheat being doubled by grinding. Coun^ 

 try hofu&ehuld fiour. Is usually ground only once, and sifted to 

 4-5th8 of the weight of the wheat. — Ammunition flour. Is re- 

 quired to be ground and sifted to 1960-2280ths, or very nearly 

 5-6ths the weight of the wheat. — BaJu'd flour^ Farina tosta. 

 Astringent ; used to make food for infants that are purged. 



Wheat flour is distinguished by its cohesiveness, which is so 

 great, that on !)eing squeezed in the hand, the lump will be some 

 time Ijefore it loses its shape. Li(|uid ammonia (acjua ammonia? 

 purse) turns it yellow ; and, if any other com has been ground 

 with it, pale brown ; or if peas or beans have been ground with 

 it, a darker brown.
