CORN. 



poses acetile and nitrate of lead, and ni- 

 tnU'- of in ic tri a;i I silver: with nitrate 

 of c jpper it Kmns no precipitate, but 

 tli'- i'lue colour of the solution pusses to 

 g.-'en, as does also that of sulphate 

 01 copper: the solution cf sulphate of 

 iron he-comes of a deep yellow, and that 

 of sulphate ot' z:uc of a clear g6lden yel- 

 low. A character peculiar to it is, that 

 when a few dro, s of it are added to a so- 

 lution of indigo :n sulphuric acid, it causes 

 the blue colour <j pass to a green. 



The characters by which it is distin- 

 guished from the known vegetable acids 

 are, 1. from the citric, by not crystallizing; 

 2. from the gallic, by not precipitating 

 iron back ; 3. from the mallic, by being 

 o'i' .'.med in a concrete form ; 4. from the 

 taruu-ic, by its volatility ; 5. from the oxa- 

 lic, by IKK precipitating the solution of 

 c ot' copper, and by yielding to it 

 lime. From these, and the various phe- 

 nomena presented in its combinations, it 

 is considered as diii'erent from all the 

 other aculs. 



CORN, in country affairs, the grain or 

 seeds of plants, separated from the ear, 

 and used for making bread. See AGKI-

CORN trade. It is evidently desirable 

 in every nation, that there siiould be plen- 

 ty of the principal articles of food ; and 

 likewise that the money price of it should 

 be ys low as possible. The policy of every 

 country, with regard to corn, should be 

 directed to these two capital objects. 



It is found by universal experience, that 

 there is no method of favouring' the pro- 

 duction of any article so safe and advan- 

 tageous, as the securing of a good price 

 to the producer; and this end is answered 

 in England by permitting the exportation 

 of corn when it is cheap ; and enabling 

 the producer, by means of a bounty that 

 usually is at least equal to the expense of 

 carriage, to sell his corn in other coun- 

 tries as cheaply as the farmers of those 

 countries. With this view, the bounty on 

 the exportation of corn was originally 

 granted, and this end it is supposed to 

 have answered. 



The general objection to all bounties 

 has already been stated. See BOI-JTTT. 

 With regard to the bounty on the expor- 

 tation of corn it may be observed, that in 

 consequence of it, the money price of corn 

 has probably been higher, than, cxt.par., 

 it otherwise would have been : but the mo- 

 ney price of corn regulates the money 

 price of labour, and, consequently, the 

 money price of all the productions of la- 



bour must be enhanced, by whatever en- 

 hances the money price of corn. The 

 bounty, therefore, has probably rendered 

 the money price of all articles of British 

 industry rather higher than it otherwise 

 would have been. Now this bad effect 

 could not arise from a bounty on produc- 

 tion, to be paid to the grower whenever 

 the market price was below a certain 

 sum; or to be paid regularly for every 

 bushel of wheat grown. If a bounty, 

 therefore, be necessary, it seems more 

 desirable that it should be given for pro- 

 duction than for exportation. 



But as the quantity of com produced 

 depends not merely on the diligence and 

 skill of the farmer, but on the nature of 

 the seasons, some degree of uncertainty 

 will necessarily exist with regard to the 

 supply for any particular year. The pro- 

 portion between the supply and the de- 

 mand will vary, and the price consequent- 

 ly will fluctuate. Popular prejudice al- 

 wavs ascribes scarcities to the farmer, 

 the miller, or the corn dealer; but an en- 

 lightened policy must regard all of these, 

 whose capitals enable them to keep a 

 large stock, and especially the last, as 

 most beneficially employed. It is their 

 interest to watch the market ; to ascertain 

 the quantity produced, and to suit the 

 supply to the demand. They purchase 

 when they find the market overstocked ; 

 they sell when it is understocked ; they 

 keep a quantity in reserve when a scar- 

 city is apprehended, and all their acti- 

 vity and property is perpetually exerted 

 to prevent the dreadful extremity of a 

 famine. 



COR>", in medicine and surgery, a hard 

 tubercle like a flat wart, growing in seve- 

 ral parts of the feet, especially upon the 

 joints of the toes. This disorder is attri- 

 buted to the wearing of too strait or nar- 

 row-toed shoes, which never fail to pro- 

 duce these tubercles, especially if the 

 person is obliged to stand or walk much, 

 and in the summer time. Various are the 

 methods used for removing these callosi- 

 ties of the skin and cuticle ; some by 

 knife, and others by application of emol- 

 lient and caustic or eroding medicines. 



As few things are more troublesome 

 than corns in the feet to those who have 

 much walking, we may observe, that the 

 pressure may be prevented in the follow- 

 ing manner : Take a piece of linen, spread 

 with any emollient plaster; lay one piece 

 over another, eight or ten, or more times, 

 and cut a hole in the middle of them, ex- 

 actly the same size and circumference as
