Sulphur chloride equal to about 20 per cent. of the weight of the oil is dissolved in a solvent like paraffin oil, and a portion—perhaps a third of the colution is added to the cotton and oil mixture. In 8 to 12 hours the cation dissolves. Oxide or carbonsta of-enlcium or magnesium is added to neutralize the acl, and the cominder of the sulphur chloriile solution is then poured in.

SNOW BLINDNESS,

Travellers in regions of snow and sunshine should wear glasses opaque to ultra-violet light- This is the conclusion of Prof. J. von Kowalki whose observations in Switzerland have shown that snow reflects the ultra-violet rays of sun- light almost completely, and have thus explained the discomfort to the eyes in snowy lands.

AN OLD ENGINE AND A HISTORICAL

HAMMER,

The passing of two notable-old machines jea reminder of the amount of labour man's me chanical servants may perform, and of the improvement that has been made. A boam engine of 100 horse-power, which began opera- ing in 1820, has just been stopped and con- demned at the Brownfield Mills, Manchester, Eagland. The engine weighs 45 tong; it has a steam-jacketed cylinder of 362 inchas, a stroke of 7 feet, and the fly-bool of 24 fest in diameter has ran at 21 revolutiong per minute. The room necessary was 40 feet long by 40 high and 15 wide. The other machina that has served ils time is a steam-hammer of the Krupp works at Essen, Germany, which was originally n radical innovation and for 30 years the most powerful tool in the forge-shop, but was superseded and on Mar. 4th was mustered out with an appropriate celebra- tion after 50 years of use. It had a 50-ton am And a 1,000-ton anvil. The cylinder had a diameter of 574 inches, the stroke was 103 feet, und the piston rod was 10 inches in diameter.

THE BLOOD is the LIFE of the FLESH

Dr. Morse's Indian Root Pills-What they are and Their Four Principal Ingredients.

what they do.

spring from one source, namely: Impurity of It is an established fact that all diseases", the Blood. Therefore our strength, health, and life depend upon the vital fluid. When the various passages become clogged, and do not act in perfect harmony with the different functions of the body, the blood loses its action, becomes thick, corrupted, and diseased, thus causing paina, sickness, and distress of every name; our strength is exhausted; and if Nature is not assisted in throwing off the stagnant humours, the blood will become choked and cease to act, and thus our light of life will be extinguished. How important, then, that we should keep the various passages of the body free and open, and if assistance is necessary to have at hand that invaluable remedy, Dr. MORSE'S INDIAN RDOT PILLS, manufactured from plants and roots which grow around the mountain cliffs in Nature's garden, for the health and recovery of diseased man.

One of the roots from which these Pills are made is a SÚDORIFIC, which opens the pores of the skin, and assists Nature in throwing out the finer parts of the corruption within.

The second is a plant which is an EXPECTORANT that opens and unclogs the passage to the lungs, and thus in a soothing manner performs its duty by throwing off the phlegm and other humours from the lungs by copious spitting.

The third is a DIURETIC, which gives ease and double strength to the Kidneys; thus encouraged, they draw large amounts of impurity from the blood, which is thrown out bountifully by the urinary or water passages, and which could not have been discharged in any other way.

The fourth is a CATHARTIC, and accompanies the other properties of the Pills while engaged in purifying the blood, and the coarser particles of impurity which cannot pass by the other outlets are thus taken up and conveyed off in large quantities by the bowels.

From the foregoing it is shown that Dr. Morse's Indian Root Pills not only enter the stomach, but become united with the blood, for they find the way to every part, and completely root out and cleanse the system from all impurity, and the life of the body, which is the blood becomes perfectly healthy; consequently all sickness and pain are driven from the system, for they cannot remain when the body becomes pure and clean.

DR. MORSE'S INDIAN ROOT PILLS are an efficient, reliable, and safe remedy placed in the market at a price within the reach of all. The Fills being sugar-coated, are pleasant to take, and retain their full medicinal properties. They are packed in amber-coloured bottles-not in cheap wooden or pasteboard boxes-and are thus aheays fresh and clean, impervious to moisture, unaffected by climatic conditions, and do not deteriorate by keeping as all liquid medicines du.
