FOO 



iimile last by hooks, E. It is also 

 furnished with a stop cock, F, below, 

 to let off the condensed water. 



Such a contrivance can be set up 

 in the feeding-house on a table, and 

 easily used, the food being conveyed 

 down an inclined plane to the feed- 

 ing-troughs, or along a hose, if it be 

 fluid. A rapid way to make water 

 boil is to place it in a tube of tinned 

 iron or copper, wound into a spinal 

 form, and running around the fire ; 

 in this way the amount of surface is 

 greatly increased, and the whole 

 brouiiht near to the fire. 



FCETUS (from /to, I bring forth). 

 A quickened child in the womb. 



Fog. a collection of vapour near 

 the earth's surface, produced by the 

 cooling of the moisture in the air. 

 Fogs lie in the morning and evening 

 over' damp, ill-drained, or marshy 

 lands, and are unhealthy, producing 

 ague and bilious fevers. 



FOGGE. Long grass and partial- 

 ly cropped grass remaining on mead- 

 ows. Also the grass after a crop. 



FOGGING. An uncommon prac- 

 tice of leaving the grass of upland 

 meadows uncut during the year, and 

 turning cattle and sheep upon it in 

 the fall and winter. 



FOIL. A thin sheet of metal. 



FOLD. A temporary enclosure 

 made with hurdles or rails, to con- 

 fine sheep. A portion may be shel- 

 tered with pine or other branches, 

 and littered with straw. 



FOLDING. The practice of en- 

 closing sheep, cows, &c., in folds, 

 either for the night to manure the 

 land, or on turnips, grass, spring rye, 

 wheat, &c., to eat it regularly and 

 manure at the same time. Folding 

 during summer is wasteful ; for the 

 304 



greater part of the urine is lost, and 

 much of the solid e.\.crement decays 

 and is volatilized or removed by waslj- 

 ing ; driving the cattle to one yard 

 and receivuig the dung on straw, 

 charcoal, or suitable matters for com- 

 posting it, would be much better econ- 

 omy. On heavy lands, the treading 

 of animals is frequently mjurious du- 

 ring folding. 



FOLIATION, or VERNATION. 

 The manner in which the young 

 leaves are Iblded in the bud. 



FOLLICLE, or FOLLICULUS. 

 In botany, a one-valved, one cell- 

 ed, many-seeded, superior, dehiscent 

 fruit. 



FOMENTATION. A warm bath- 

 ing applied to a part of the body : in- 

 fusions of herbs are often used. 



FONTANEL. A sn)all space ex- 

 isting between the bones of the head 

 in the fcetus. 



FOOD. A substance which con- 

 tains any of the principles which ex- 

 ist in the body, is digestible, and not 

 combined with a poisonous ingredi- 

 ent. There are three principal vari- 

 eties of food : 1st. That capable of 

 repairing the waste of the flesh or 

 muscle, called Azotizcd food, and es- 

 sential to the strength of animals. 

 2d. That which sustains the heat of 

 the body, called non-Azolized food. 

 3d. That which repairs the waste of 

 fat, and called Oleaginous food, the 

 importance of which is inferior to the 

 two former, except for fattening ani- 

 mals. 



The azotized elements of food, so 

 called from containing azote, or nitro- 

 gen, are fibrin, casein, and albumen ; 

 they go to the repair of muscles, 

 membranes, &c., which, in the active 

 state of the body, are being perpetu- 

 ally consumed. Seeds and meats 

 contain most of these principles ; the 

 former from 10 to 20 per cent., and 

 lean meat 23 to 25 per cent. The 

 richest seeds are beans, pease, wheat, 

 barley, oats, rye, corn. This kind of 

 food IS most serviceable for draught 

 animals and such as are used for 

 strength and fleetness. For the com- 

 parative values, see the table in arti- 

 cle Fodders. They are the only class
