[3] The medical stores for each sledge were:--2 phials of sal volatile and aromatic spirits of ammonia; 2 phials of laudanum; 2 phials of wine of opium; a small tin of Gregory's powders; 12 papers (10 grains each) of Dover's powders; 32 papers (15 grains each) of chalk powders; 30 papers (4 grains each) of sugar of lead; a bottle of turpentine liniment; a phial of carbolic acid; glycerine ointment; white ointment; carbolic plaster; 4 dozen purgative pills; oil silk. Sponge, pins, expanding splints, and carbolized tow, cotton wool, a catheter, a tourniquet, a truss with pad, a lancet, twill, Persian gauze, 2 eye shades, small splint, scissors, flannel ice goggles, tape, mustard, 3 calico bandages, 2 flannel bandages, and lint. These stores were in a wooden case, and a medicine tin for bottles, together weighing 4 lbs.; while their contents weighed 7 lbs. 11 ozs., together, 12 lbs. [4] Our available force was much smaller than that of the expeditions under Sir Horatio Austin (1850-51), and Sir Henry Kellet (1852-54). They enjoyed the great advantage of having a third larger force--ninety instead of sixty men. [5] The sledges for carrying boats have the two end cross-bars fitted with two cleats, one on each side of the boat's keel. These cleats are seven inches long, and are securely lashed to the cross-bars. Two battens of American elm, each two inches wide and half an inch thick, are lashed in a fore and aft direction to the top of the cross-bars three and a half inches apart, that is to say one and three-quarters inch on each side of the central bearer. They are sufficiently long to allow of being secured to all the cross-bars. When the boat is placed on the sledge the keel rests on the cross-bars between the cleats, and is held in an upright position by one long cushion of stout canvas, stuffed with cork cuttings, on each side, and these are kept in their places by lashings. [6] As Sir Edward Parry's attempt to reach the Pole was the only extended journey that was ever undertaken due north across the Polar Sea, until the second attempt was made by the northern division of sledges under my command, it will be well to give, in this place, the details of Parry's equipment and the result of his expedition.
