The area of the steam pipe is usually made less than the area of the eduction pipe, especially when the engine is worked expansively, and with a considerable pressure of steam. In the case of ordinary condensing engines, however, working with the usual pressure of from 4 to 8 lbs. above the atmosphere, the area of the steam pipe is not less than a circular inch per horse power.
Besides this practical labor, there is the publication of nine daily charts on which are inscribed 2160 readings of different instruments, giving an accurate view of the general meteoric condition; monthly charts and charts condensing the results of years of observation; records furnished for the study of scientific men more comprehensive and regular than can be offered by any similar institution in any country.
The circulating pump was removed to the position shown, and a direct connection substituted for the S-bend. In this way the condensing equipment was made practically separate for each turbine, as it should have been in the first place. With the new piping a vacuum of 24 inches on the peak could be reached. While this is far from an efficient value, yet it is better than the former figure.
"To determine the temperature of the dew point by Daniell's dew point hygrometer and Regnault's condensing hygrometer, and by the use of the dry and wet bulb thermometers, as ordinarily used, and their use when under the influence of the aspirator, causing considerable volumes of air to pass over both their bulbs, at different elevations, as high as possible, but particularly up to heights where man may be resident, or where troops may be located, as in the high table-lands and plains of India; with the view of ascertaining what confidence may be placed in the use of the dry and wet bulb thermometers at those elevations, by comparison with Daniell's and Regnault's hygrometers; and also to compare the results as found by the two hygrometers together.
Colliers also were arriving with coal to supply motive power, both for the transit of troops and also for the purpose of condensing from the sea fresh water for the use of men and animals. The Bellona, in company with numerous other ships, now proceeded up the Red Sea.
MY DEAR JOHN: It will not be necessary for you to send me a stone-heap or a section of pasture-wall for inspection. I would rather venture an opinion from your description. Of course, these walls alone, if solid, as they doubtless must be, will be cold and damp; they must be furred off within to prevent moisture from condensing on the walls of the rooms.
'I'm not afraid, said Tom, condensing his remarks to their minimum as his only chance of being intelligible. 'You are. 'I'm not. It's just that I A nasty gleam came into Sally's eyes. Her manner was haughty. 'It doesn't matter. She paused. 'I've no doubt Ted Pringle will do what I want.
The wood is distilled in large iron retorts connected to apparatus for condensing the distillation products. This crude wood acid is distilled, and the wood spirit which distils off first is collected separately from the acetic acid which afterwards comes over. The crude wood spirit is mixed with milk of lime, and after standing for several hours is distilled in a rectifying still.
But the work of arranging these tissues and condensing them into compact organs was to be done by the next higher group, the worms. Let us now take a glance at certain stages of embryonic development which correspond to these earliest ancestral forms.
Sanjaya said, "Seeing the Dhritarashtra divisions arrayed in order of battle, Pandu's son of virtuous soul, king Yudhishthira the just, addressed Dhananjaya, saying, 'Men are informed from the words of that great Rishi Vrihaspati that the few must be made to fight by condensing them, while the many may be extended according to pleasure.
