well-known instrument, used by surgeons, barbers, &c. for shaving off the hair from various parts of the body.—As shaving to many people is a most painful operation, cutlers in different countries have long applied their skill to remove that inconvenience. Some have invented soaps of a peculiar kind to make the operation more easy, and some have invented traps. With respect to razors, some artists have succeeded rather by accident than from any fixed principle; and therefore we have found great inequality in the goodness of razors made by the same artist.

A correspondent assures us, that he has for 40 years past been at much pains to find out razors made by the best makers both in England and Scotland, and was fortunate enough, at last, to discover a kind made by a Scotchman of the name of Logan, which he called magnetic razors, because they were directed to be touched with an artificial magnet before using. These, our friend assures us, are most excellent razors, and he has used them for upwards of 20 years. He says likewise that they continue in good order, without requiring to be ground; but that the great drawback on their being generally used, is the price, which is higher than most people are able or disposed to give for that instrument. Our correspondent, who resides in the vicinity of London, also informs us, that lately the famous surgeon's instrument-maker, Mr Savigny in Pall Mall, after numberless experiments, in the course of above 20 years, has at length brought razors to a degree of perfection never yet equalled; and with such certainty, that the purchaser is in no danger of a disappointment, though the price is very moderate. By these, we are told, the operation of shaving is performed with greater ease, more perfectly, and more expeditiously than with any other.
