หน้า 373 - PATENT was trumpt up, and the patentee was countenanced by some persons of quality — and what, with the patent being in our way, and the richest of our partners being afraid to offend great men in power, who had their eye upon us, it caused the thing to cool, and the making thereof was neither proceeded in by us, nor possibly could be by him that had the patent ; because neither he that hath the patent, nor those that have countenanced him, can make one plate fit for use...
หน้า 505 - The cause of rain, therefore, is now, I consider, no longer an object of doubt. If two masses of air of unequal temperatures, by the ordinary currents of the winds, are intermixed, when saturated with vapour, a precipitation ensues. If the masses are under saturation, then less precipitation takes place, or none at all, according to the degree. Also the warmer the air, the greater is the quantity of vapour precipitated in like circumstances...
หน้า 355 - This fault is quite independent of air bubbles or flaws, which are always discoverable in turning by the lathe. and both the sides of every plate being soaked alike in the lies. In this liquor they remain for ten or twelve hours standing on the edges, but they are turned, or inverted, once during that time. This operation is called working in the lies. The next operation is that of steeping in a mixture of sulphuric acid and water, in proportions which vary according to the judgment of the workmen....
หน้า 372 - Saxony ; and coming to the works, we were very civilly treated, and, contrary to our expectation, we had much liberty to view, and see the works go — with the way and manner of their working and extending the plates, as also the perfect view of such materials as they used in clearing the plates, to make them fit to take tin, with the way they use in tinning them over, when cleared from their rust and blackness.

The calcination of magnesia had at that time been practised only in connexion with philosophical inquiries. Dr Black, in an essay which is still perhaps not surpassed in chemical philosophy as...
หน้า 351 - ... the plates, which are put into the oven in rows, and arranged three in each row, until the oven is full. It will be obvious that if they lay flat on the floor of the oven, the flame could play only on one side of each plate, whereas, by being bent in the form already described, the flame can operate equally on both sides. It may here be remarked that the form of all tin-plates, one sort excepted, is that of a parallelogram, and that if a piece of stiff...

The operation of cleansing, as it is called, and which is preparatory to the process of scaling, is commenced by steeping the plates for the space of four or five minutes, in a mixture of muriatic acid and water, in the proportion of four pounds of acid to three gallons of water. This quantity...
