y, but the effect is not so pleasing unless it be introduced with scenic devices or machines, such as paddles, wheels, mills, or moving automatons which require a supply of water to make them constant. Aquarium. In 1849 N. B. Ward grew sea-weed in artificial sea-water. A great aquarium, one hundred and fifty feet long and thirty-six feet wide, was constructed in 1860 in the Jardin d'acclimation in Paris by Alford Lloyd of London. The same gentleman erected a magnificent aquarium in Hamburg. Cutting's aquarium. Fig. 286 shows an arrangement for the introduction of air for the revivification of the water. It is an air-forcing apparatus consisting of an inverted weighted vessel whose edges are submerged in the water of the reservoir, and which connects by a flexible pipe with the interior of the tank. As the inverted weighted air-holder descends gradually, it forces air through the flexible pipe into the aquarium. The aquarium of the Paris Exposition was a remarkab

A Danish paper states that Herr Woerman, shipowner of Hamburg, has been commissioned to procure a coffin for his present Majesty the King Jberio, on the west coast of Africa. The coffin is of fir-wood, polished on the outside, and furnished very comfortably. It is lined with red velvet, and has soft velvby certain instrument-makers for the production of exact divisions of scales, and generally for the determination of very minute differences of length. This device was invented about the year 1820, by Repsold, a celebrated instrument-maker of Hamburg, whose mechanical genius first manifested itself in the repairing of chronometers while he was mate of a vessel at sea. It consists of a very delicate level pivoted at its middle and across its length, with a small tilt-weight at one end, whi
be imprisoned in the chamber, to adapt the instrument to work in an atmosphere of any temperature, with a bubble of a normal size. Mr. Wurdemann was the first to hermetically seal a tube containing the chamber, previous to which time it was closed by glass plates, bladder, and glue. The most curious and delicate apparatus for leveling, in dividing and graduating instruments, and adapted for many other purposes, is the contact-level invented by Repsold, a celebrated instrument-maker of Hamburg. It is described on page 612, and room cannot be spared for duplicate descriptions. Mine-levels. 2. (Mining.) a. A horizontal gallery or passage in a mine. The workings at different depths are said to be at the different levels,—the 50 or 60 fathom level, and so on. b. An adit or drift forming a drain for water. A level which opens to the surface at the side of a valley is called a day-level, and forms a means of natural drainage without pumping. A drowned or blind level
e are claimed to have resulted generally from improper manufacture, exposure to too great heat in transportation, or carelessness in handling. Mowbray's nitro-glycerine Apparalus. Among the most prominent accidents occurring from these sources were the explosions at Aspinwall and in the office of Wells, Fargo, & Co. at San Francisco, by the former of which forty-five and by the latter six lives were destroyed. In the case of the Aspinwall disaster the nitroleum had been shipped from Hamburg, where the temperature was 55° or 60° to a tropical climate where the temperature in the hold of the steamer was probably more than double this. It was inclosed in cork-stopped vessels, packed in cases with sawdust. The explosion has been attributed to the disengagement of gas, which, by the corrosion of the corks, escaped into the surrounding sawdust, forming a new and easily ignited compound, which, becoming mixed with the undecomposed nitroleum which escaped, was easily exploded at s
er cent, at least, of all the storm-warnings had proved correct, and in 1865 that seventy-three per cent had been fully verified. In France, during the years 1865, 1866. out of one hundred warnings sent, seventy-one were realized the first year, and seventy-six in the second year; and out of one hundred storms which occurred, eighty-nine were signaled during the first winter, and ninety-four during the second. The North German Seewarte mentions that out of thirty stormwarnings hoisted at Hamburg, ninety-four per cent were correct. The system in the United States is gaining the confidence of navigators, and is yearly growing more correct. A number of disastrous storms have been predicted with marvelous precision from Washington, and our daily weather-forecasts very seldom fail to express the general atmospheric conditions. and usually fore-announce the changes to within an hour or two of their occurrence.

The first water-works in the United States were planned and constructed by Mr. John Christopher Christensen, at Bethlehem, Pa., in 1762. The machinery consisted of three singleacting force-pumps, of 4-inch cainc are also used; the former as an adulteration, the latter as a substitute. White-lead is the carbonate of lead, produced from the metal. See white-lead. Venice white is a mixture of equal parts of white-lead and sulphate of baryta. Hamburg white is lead, 1; baryta, 2 parts. Dutch white has lead, 1; baryta, 3 parts. Clichy white is pure carbonate of lead. Kremnitz white, krems white, and silver white are synonyms of white-lead. Zinc-white, an oxide of zinc. See zinc-wh
