deposit of silver, which, however, tarnishes with the sulphurous gases produced on firing. It is also very expensive, which, of course, renders its application impracticable for the army. It was always known that the use of nickel would obviate both these disadvantages, being exceedingly hard and capable of taking a very high polish. The difficulty, however, has been that it could not be deposited by any known process, although partial success has been achieved by Becquerel, Kurtz, and others. But the Adams' process of the American Nickel Company has overcome this difficulty, as has been clearly demonstrated by searching experiments. In one experiment two revolvers were taken, one of them being coated with nickel by the above-named process, and the other being carefully covered with oil. They were buried together for some time in wet sand, the result being that the nickelled weapon came out bright and as free in movement as when buried, whilst the other was clogged and coated with rust. The introduction of this improvement will prove of great value both to the troops and to the country-saving the former much labour, and the latter much expense in preserving military arms. THE MARTINI-HENRY RIFLE AT exhibited a very unfriendly feeling towards the in that place who well remember his coming, and who think it was by no means hard work to get him to take an office which afterwards he felt so galling. He has taken trouble enough to dull the polish of our characters, and he has not spared the reputamalignity. Many of those who are censured in Mr tions of those who are beyond the reach of his Ansell's book (which is indeed in one sense an obituary) have departed, and the author has evidently forgotten the trite maxim that "silence is a duty where we cannot praise the dead." You, Sir, have dealt practically with the question of loss by coinage, but I repeat that it is not possible to convert 10 or 12 tons of golden ingots into a million of sovereigns without waste. Matter we all know is indestructible, but when it is widely possible to collect its every particle. Let any spread, as in the operations of minting, it is imperson visit the Mint during a coinage of gold and he will see spangles and glistening atoms of the metal in all directions. In fact, he will in all probability carry away some on his clothes, and thus become an involuntary thief. When, therefore, Mr. Ansell and those who mistake his dictum for gospel say that gold coinages can be conducted without a fair amount of loss or waste, they either wantonly deviate from the truth or fall into egregious error. In either case they libel the employes of the Mint, and are guilty of injustice. We want to perform our duties honourably and in peace so long as we are in the Mint, and to leave it, if need be, with unspotted characters. Fortunately we have in the present deputy-master and worker of the FOUR competitors fired with th Martini-Heinry 11th of June, weighed anchor and departed for the Mint a high-minded and unprejudiced gentleman, rifles, and, great as were the expectations which had been excited, the closeness and constancy of the fire took every one by surprise. It resembled the file firing of a company, and the discharges were so frequeat that long before the expiration of the allotted three minutes the marksmen were impeded by the smoke of their own rifles, and had to aim at the targets through a haze. The reckoning was awaited with the utmost curiosity; when it came, it appeared that of the four competitors one had fired 46 shots, two others 47 each, and the fourth 55 shots. No. 1 made an aggregate score of 72; No. 2 scored 101; No. 3 made 128; while No. 4 scored no less than 151, his shots having in every case struck the target, thus making 16 bull's-eyes, 18 centres, and 21 outers. The total number of hits made by the four competitors within three minutes was 158. Conceive the effect of weapons such as these directed from the walls of a city upon an attacking party.

Here their first difficulty was encountered in the shape of hostile natives, wh from the beginning to the end annoyed the party by their jealousy of foreigners and their tricks to mislead them in their endeavours to survey the route. The Indians are small in stature and exceedingly treacherous. It was only by the utmost exertions that a sufficient number were brought over to interpret and act as guides. There are between 40,000 and 50,000 on the isthmus, divided into three tribes, the two most powerful of which are the Sassardi and Morti. The latter have their habitation on the isles and shoals adjacent to the coast, where they live on fish and crabs; while the Sassardi, the largest and most powerful, dwell in the dense jungles and subsist on the tropical fruit and other products which they raise when not too lazy to work. During the whole time spent in the country but one or two women were seen. On acount of the celebrity that had been given to "Dr. Cullen's route," which was supposed to have been the most practicable, the first expedition was started on that road on the 28th day of February under command of Lieutenant L. Hubbard; but after many privations and immense quantities of rain that deluged the country, they were obliged to put back. Two days afterwards Captain Selfridge, accompanied by Lieutenant Schultz and Major Houton, of the Marines, with sixty men and a full corps of surveyors, started over the Cordillera mountains in charge of an Indian guide of the Sassardi tribe. They took Strain's old route along the Sucubti River towards the Pacific slope, and on the banks of that stream, when a few days out, Captain Selfridge held a "pow-wow" with the Chief of the Sassardis on the River Diablo, who THE MINT IN PARLIAMENT.

We learn by a private telegram from New York that the "Cambria" arrived at Sandy Hook Lightship on the 27th inst., at seven minutes past three in the afternoon. She was met down the river by a large number of yachts and steamers, and was enthusiastically cheered the whole way up to Staten Island. The Dauntless" arrived an hour and a quarter to the "Cambria" taking a northerly course, reachafterwards, but the yachts never sighted each other after the night of the start. This fact was owing ing as high as 55 N., while the "Dauntless" kept the southern track. The "Cambria " carried away two foretopmasts, but had spare ones on board to replace them. She met with no other mishap, and arrived at New York all well. She had strong westerly winds and fresh gales to Cape Race, which had light head winds to Sandy Hook. The “ she sighted on Monday, the 18th. After that she Dauntless" had a succession of strong north-west winds with occasional gales and calms. THE total number of vessels which have passed through the Suez Canal is 363; of these 130 traversed during the four days of the inauguration exempt from payment of dues, leaving 233 ships, representing 195,428 tons; when to this is added the tonnage of small craft, viz., 6,498, the total amount on which dues have been paid is 201,926 tons, composed as follows:-153 British ships, 134,712 tons; 35 French ships, 33,804 tons; 19 Egyptian ships, 12,760 tons; nine Austrian ships, 5,948 tons; seven Italian ships, 3,717 tons; four Turkish ships, 2,548 tons; three Spanish ships, 732 tons; one Russian ship, 480 tons; one Indian ship, 686 tons; one Chinese ship, 37 tons-total 233 ships, 195,428 tons, including the fractional tonnage. The receipts in June amounted to 817,117f. equal to £32,684 being nearly double those of the preceding month, and the total revenue derived from all sources made, up to June 30, amounted to 3,244,6161. equal to £129,784.

The balloons horses were subjected. hood at the terrible sufferings to which the two are made of airproof and waterproof rubber cloth, shaped like balloons, and covered with strong rope network, to which the lifting attachments are made. The mode of inflation is very ingenious. Metal cylinders, fitted with pipes and valves communicating with the mouths of the balloons, are charged with zinc filings and sulphuric acid. They are then lowered into the water, the opening of the valves allows the zinc particles to fall into the acid, hydrogen gas (so much lighter than common air) is rapidly evolved and conducted to the interior of the balloons. When inflation is complete, a stop-cock shuts the gas securely in the balloons, aided by the pressure of the surrounding water. The services of a diver are required in the process of inflation.
