USEFUL INFORMATION.

The influence of arnsal respiation on the ear is illustrated by Mr. George Gatlin in his history of “The North American Indians.” Among 2,000,000 Indians he found not one who was deaf or breathed through the mouth, except three or four deaf mutes: and, in the memory of the chiefs of 150 tribes, not one case of deafness could he remembered to have occurred. This is explained by the mother always closing the mouth of the child whenever it attempted to breathe through it. It is known that ozone, when properly applied, is a most effective and convenient agent for restoring books or prints which have become brown by age, or been smeared or soiled with coloring matter—only a short time being required to render them perfectly white, as if just from the press, and this without injuring in the least the blackness of the ink. An example given of the results produced in this way is that of a book of the sixteenth century, upon a page of which several sentences had been painted over by the monks of that day with a black, shining coloring matter, in order to render them illegible, and of which no trace of a line couldbe detected. After thirty-six hours’ treatment with ozone, the coloring matter was entirely destroyed the most careful scrutiny of the page failing to disclose the fact that any of the lines had once been painted over. Writing ink may readily be discharged by ozone, especially if the paper be subsequently Ireited with very dilute chlorhydric acid to remove the oxide of iron.

The Cause and Cure on Snoring.— A wiiter in the Scientific Monthly tells how the habit of snoring is acquired, and, better, how it may be cured: And, first, the cause: We all know that the air reaches the lirngs through two channels, the nose and the mouth. The two currents meet in the throat below the soft palate, the end of which hangs loose and swings backward and forward, producing the snoring. If the air reaches the lungs as it should, through the nose, no noise will be made, If it reaches the same through the mouth, the palate will make more noise, since it is not the natural channel, but when it' rashes through both channels then it is that the sound sleeper banishes rest from the pillows of his companions by bis hideous noise. The remedy for snoring is to keep the mouth closed; and for this purpose Dr. Wyeth, the wiiter of the article referred to, has invented an article so cheap that any one can make it, and no snorer should be without it. It consists of a simple cao fit iug the head snugly, and a piece ’of soft material fitting the chin. These are connected by elastic webbing, which is connected with the heal cap near the ears. This conti ivance prevents the jaw from dropping down, and thereby renders snoring impossible. Tho great trouble will be to get people to adopt this invention, since the most honest and upright people rarely, if ever, admit that they snore, and will be very indignant if accused of it. As a further inducement to this contrivance of Dr. Wyeth, it may be added that breathing through the mouth is very detrimental to the health, and that many diseases of the throat and luDgs are contracted or aggravated thereby. Splitting Paper.— lt is one of the most remarkable properties of that wonderful product, paper, says Design and Work, tnat it can bo split into two or even three parts, however thin the sheet. We have seen a leaf of the Illustrated News thus divided into three thin leaves. One consisted of the surface on which the engravings are printed; another was the side containing the letter press, and a perfectly blank piece on each ?ide was the paper that lay between. Many people who have not seen this done might think it impossible; yet it is not only possible but extremely easy, as we shall show. Get a piece of plate glass and place on it a sheet of paper; then let the latter be thoroughly soaked. With care and a little dexterity the sheet can be split by the top surface being removed. But the best plan is to paste a piece of cloth or strong paper to each side of the sheet to be split. When dry, violently and without hesitation pull the two pieces asunder, when part of the sheet will be found to have adhered to one and yart to the other. Soften the paste in water and the pieces can be easily removed from the cloth. The process is generally demonstrated as a matter of curiosity, yet it can be utilized in various ways. If we want to paste in a scrap book a newspaper article printed on both sides of the paper, and possess only one copy, it is very convenient to know how to detach the one side from the other. The paper when split, as may be imagined, is more transparent than it was before being subjected to the operation, and the printing ink is somewhat duller; otherwise the two pieces present the appearance of the original if again brought together. Some time ago the information of bow to do this splitting was advertised to be sold for a considerable sum. We now impart it to all our readers gratuitously.
