By triangulation Lord Longlegs determined its altitude; Herr Spider measured its circumference at the base and computed the circumference at its top by a mathematical demonstration based upon the warrant furnished by the uniform degree of its taper upward.
"The work of the Coast Survey," writes Mr. Alfred Brooks, "is more refined than the rough triangulation done by our men; at the same time they were much further away." There are, however, two sources of error in the determination of the height of this mountain by triangulation a general one and a particular one.
You can get any man's or woman's secret, whose sphere is circumscribed by your own, if you will only look patiently on them long enough. Nature is always applying her reagents to character, if you will take the pains to watch her. Our studies of character, to change the image, are very much like the surveyor's triangulation of a geographical province.
The determination of the heights of mountains by triangulation is, of course, the method that in general commends itself to the topographer, though it may be questioned whether the very general use of aneroids for barometric determinations has not thrown this latter means of measuring altitudes into undeserved discredit when the mercurial barometer is used instead of its convenient but unreliable substitute.
It may be, then, that political economy, in spite of its individualistic tendency and its exclusive affirmations, is a constituent part of social science, in which the phenomena that it describes are like the starting-points of a vast triangulation and the elements of an organic and complex whole.
At the present time, Professor Lowell states that this "curious triangulation has been traced over almost every portion of the planet's surface, whether dark or light, whether greenish, ochre, or brown in colour." In some parts they are much closer together than in others, "forming a perfect network of lines and spots, so that to identify them all was a matter of extreme difficulty."
Ten principal points have been determined in latitude and longitude by means of 115 sets of astronomical observations, aided by three good chronometers, and seventeen other points have been determined by triangulation with a portable theodolite.
Voluminous data were collected; meridian observations of the stars of reference for Victoria occupied twenty-one establishments during four months; the direct work of triangulation kept four heliometers in almost exclusive use for the best part of a year; and the ensuing toilsome computations, carried out during three years at the Cape Observatory, filled two bulky tomes with their details.
"Some geometrical stunt, maybe; triangulation, or " "Why, sure! That's just it!" exploded Bill. "I know how we can get him: Parallax! Shucks, it'll be easy! Just leave it to me." "Looks as though some kind of Napoleonic strategy were going to be pulled off," asserted Professor Gray, laughing. "But, boys, keep in mind that Mr.
The discovery was fatal to all further progress in the triangulation. However conscientiously the assistant on the Spanish coast might look to the kindling of the beacon, Rosette had no glances to spare for that direction; he had no eyes except for the one object of his notice, no thoughts apart from that one quarter of the firmament. A comet! No time must be lost in calculating its elements.
