So, you see, I shall live like an alderman; I mean, if I am to go to every part of the island, heathen and all. Perhaps 20,000 people, scattered over many miles. I say heathen and all, ...

... from its proud place. I like the Bhishti and respect him. As a man he is temperate and contented, eating bajri bread and slaking his thirst with his own element. And as a servant he is laborious and faithful, rarely shirking his work, seeking it out rather. For example, we had a bottle-shaped filter of porous stoneware, standing in a bucket of water which it was his duty to fill daily; but the good man, not content with doing his bare duty, took the plug out of the filter and filled it too. And all the station ...

... with the clear filtrate. There are a number of such filters of different degrees of porosity manufactured, and they are often used to procure pure water for drinking, for which use they are more or less, generally however, less efficacious. The filter has the form of a hollow cylinder and the liquid to be filtered is forced through it under pressure. For domestic use the filter is attached by its open end to the water tap and the pressure from the mains forces the water through it. In laboratory uses, denser ...

These disadvantages are overcome by the filter press process, which was first introduced into Great Britain by the Belgian engineer P. Meura. The malt, in this method of brewing, is ground quite fine, and although an ordinary mash-tun may be used ...

We all knew he was brilliant and felt certain that the great ones in the college would soon find it out. And they did; for ever and anon some news would filter through to us that Sant was battening upon Latin, Greek, mathematics, science, and history. Of course, we gave all the credit to our little school, and seemed to forget that the Lord may have had something to do with it. When we proved by Sant's achievements that our ...

The iron particles can then be filtered from the liquid by pouring the entire mixture upon a piece of filter paper folded so as to fit into the interior of a funnel (Fig. 1). The paper retains the solid but allows the clear liquid, known as the filtrate, to drain through. The iron particles left upon the ...

But the exotic feature of the grove is its wealth of creeping vines that clamber up the trunks, swinging from one tree-top to another, and allowing the merest threads of sunlight to filter through their matted canopy. Policoro has the tangled beauty of a tropical swamp. Rank odours arise from the decaying leaves and moist earth; and once within that verdant labyrinth, you might well fancy ...

This substance was then employed to filter the beams of the electric light, and to form foci of invisible rays so intense as to produce almost all the effects obtainable in ordinary fire. Combustible bodies were burnt, and refractory ones were raised to a white heat, by ...

But all emotions and all ends of a nobler character had seemed to filter themselves free from every golden grain in passing through the mechanism of Randal's intellect, and came forth at last into egotism clear and unalloyed.
