On the Economy of Machinery and Manufactures

by Charles Babbage

188. The practice, in retail linen-drapers' shops, of calling certain articles yard wide when the real width is perhaps, only seven-eighths or three-quarters, arose at first from fraud, which being detected, custom was pleaded in its defence: but the result is, that the vender is constantly obliged to measure the width of his goods in the customer's presence. In all these instances the object of the seller is to get a higher price than his goods would really produce if their quality were known; and the purchaser, if not himself a skilful judge (which rarely happens to be the case), must pay some person, in the shape of an additional money price, who has skill to distinguish, and integrity to furnish, articles of the quality agreed on. But as the confidence of persons in their own judgement is usually great, large numbers will always flock to the cheap dealer, who thus, attracting many customers from the honest tradesman, obliges him to charge a higher price for his judgement and character than, without such competition, he could afford to do.

189. There are few things which the public are less able to judge of than the quality of drugs; and when these are compounded into medicines it is scarcely possible, even for medical men, to decide whether pure or adulterated ingredients have been employed. This circumstance, concurring with the present injudicious mode of paying for medical assistance, has produced a curious effect on the price of medicines. Apothecaries, instead of being paid for their services and skill, are remunerated by being allowed to place a high charge upon their medicines, which are confessedly of very small pecuniary value. The effect of such a system is an inducement to prescribe more medicine than is necessary; and in fact, even with the present charges, the apothecary, in ninety-nine cases out of a hundred, cannot be fairly remunerated unless the patient either takes, or pays for, more physic than he really requires. The apparent extravagance of the charge of eighteen pence for a two-ounce phial(1*) of medicine, is obvious to many who do not reflect on the fact that a great part of the charge is, in reality, payment for the exercise of professional skill. As the same charge is made by the apothecary, whether he attends the patient or merely prepares the prescription of a physician, the chemist and druggist soon offered to furnish the same commodity at a greatly diminished price. But the eighteen pence charged by the apothecary might have been fairly divided into two parts, three pence for medicine and bottle, and fifteen pence for attendance. The chemist, therefore, who never attends his customers, if he charges only a shilling for the same medicine, realizes a profit of 200 or 300 per cent upon its value. This enormous profit has called into existence a multitude of competitors; and in this instance the impossibility of verifying has, in a great measure, counteracted the beneficial effects of competition. The general adulteration of drugs, even at the extremely high price at which they are retailed as medicine, enables those who are supposed to sell them in an unadulterated state to make large profits, whilst the same evil frequently disappoints the expectation, and defeats the skill, of the most eminent physician.

It is difficult to point out a remedy for this evil without suggesting an almost total change in the system of medical practice. If the apothecary were to charge for his visits, and to reduce his medicines to one-fourth or one-fifth of their present price, he would still have an interest in procuring the best drugs, for the sake of his own reputation or skill. Or if the medical attendant, who is paid more highly for his time, were to have several pupils, he might himself supply the medicines without a specific charge, and his pupils would derive improvement from compounding them, as well as from examining the purity of the drugs he would purchase. The public would gain several advantages by this arrangement. In the first place, it would be greatly for the interest of the medical practitioner to have the best drugs; it would be in his interest also not to give more physic than needful; and it would enable him, through some of his more advanced pupils, to watch more frequently the changes of any malady.

190. There are many articles of hardware which it is impossible for the purchaser to verify at the time of purchase, or even afterwards, without defacing them. Plated harness and coach furniture may be adduced as examples: these are usually of wrought iron covered with silver, owing their strength to the one and a certain degree of permanent beauty to the other metal. Both qualities are, occasionally, much impaired by substituting cast- for wrought-iron, and by plating with soft solder (tin and lead) instead of with hard solder (silver and brass). The loss of strength is the greatest evil in this case; for cast iron, though made for this purpose more tough than usual by careful annealing, is still much weaker than wrought-iron, and serious accidents often arise from harness giving way. In plating with soft solder, a very thin plate of silver is made to cover the iron, but it is easily detached, particularly by a low degree of heat. Hard soldering gives a better coat of silver, which is very firmly attached, and is not easily injured unless by a very high degree of heat. The inferior can be made to look nearly as well as the better article, and the purchaser can scarcely discover the difference without cutting into it.

191. The principle that price, at any moment, is dependent on the relation of the supply to the demand, is true to the full extent only when the whole supply is in the hands of a very large number of small holders, and the demand is caused by the wants of another set of persons, each of whom requires only a very small quantity. And the reason appears to be, that it is only in such circumstances that a uniform average can be struck between the feelings, the passions, the prejudices, the opinions, and the knowledge, of both parties. If the supply, or present stock in hand, be entirely in the possession of one person, he will naturally endeavour to put such a price upon it as shall produce by its sale the greatest quantity of money; but he will be guided in this estimate of the price at which he will sell, both by the knowledge that increased price will cause a diminished consumption, and by the desire to realize his profit before a new supply shall reach the market from some other quarter. If, however, the same stock is in the hands of several dealers, there will be an immediate competition between them, arising partly from their different views of the duration of the present state of supply, and partly from their own peculiar circumstances with respect to the employment of their capital.

192. The expense of ascertaining that the price charged is that which is legally due is sometimes considerable. The inconvenience which this verification produces in the case of parcels sent by coaches is very great. The time lost in recovering an overcharge generally amounts to so many times the value of the sum recovered, that it is but rarely resorted to. It seems worthy of consideration whether it would not be a convenience to the public if government were to undertake the general conveyance of parcels somewhat on the same system with that on which the post is now conducted. The certainty of their delivery, and the absence of all attempt at overcharge, would render the prohibition of rival carriers unnecessary. Perhaps an experiment might be made on this subject by enlarging the weight allowed to be sent by the two-penny post, and by conveying works in sheets by the general post.

This latter suggestion would be of great importance to literature, and consequently to the circulation of knowledge. As the post-office regulations stand at present, it constantly happens that persons who have an extensive reputation for science, receive by post, from foreign countries, works, or parts of works, for which they are obliged to pay a most extravagant rate of postage, or else refuse to take in some interesting communication. In France and Germany, printed sheets of paper are forwarded by post at a very moderate expense, and it is fit that the science and literature of England should be equally favoured.

193. It is important, if possible, always to connect the name of the workman with the work he has executed: this secures for him the credit or the blame he may justly deserve; and diminishes, in some cases, the necessity of verification. The extent to which this is carried in literary works, published in America, is remarkable. In the translation of the Mecanique Celeste by Mr Bowditch, not merely the name of the printer, but also those of the compositors, are mentioned in the work.

194. Again, if the commodity itself is of a perishable nature, such, for example, as a cargo of ice imported into the port of London from Norway a few summers since, then time will supply the place of competition; and, whether the article is in the possession of one or of many persons, it will scarcely reach a monopoly price. The history of cajeput oil during the last few months, offers a curious illustration of the effect of opinion upon price. In July of last year, 1831, cajeput oil was sold, exclusive of duty, at 7 d. per ounce. The disease which had ravaged the East was then supposed to be approaching our shores, and its proximity created alarm. At this period, the oil in question began to be much talked of, as a powerful remedy in that dreadful disorder; and in September it rose to the price of 3s. and 4s. the ounce. In October there were few or no sales: but in the early part of November, the speculations in this substance reached their height, and between the 1st and the 15th it realized the following prices: 3s. 9d., 5s., 6s. 6d., 7s. 6d., 8s., 9s., 10s., 10s. 6d., 11s. After 15 November, the holders of cajeput oil were anxious to sell at much lower rates; and in December a fresh arrival was offered by public sale at 5s., and withdrawn, being sold afterwards, as it was understood, by private contract, at 4s. or 4s. 6d. per oz. Since that time, 1s. 6d. and 1s. have been realized; and a fresh arrival, which is daily expected (March, 1832) will probably reduce it below the price of July. Now it is important to notice, that in November, the time of greatest speculation, the quantity in the market was held by few persons, and that it frequently changed hands, each holder being desirous to realize his profit. The quantity imported since that time has also been considerable.(2*)

195. The effect of the equalization of price by an increased number of dealers, may be observed in the price of the various securities sold at the Stock Exchange. The number of persons who deal in the 3 per cent stock being large, any one desirous of selling can always dispose of his stock at one-eighth per cent under the market price; but those who wish to dispose of bank stock, or of any other securities of more limited circulation, are obliged to make a sacrifice of eight or ten times this amount upon each hundred pounds value.
