... the shores of the Great Lakes, our army has been fairly free from this dread visitation. The campaigning area of the coast and the railway line of British East Africa that gave our men malaria in plenty during the first two years of war, had not provided many of those focal areas in which this disease is distributed. The Loyal North Lancashires and the 25th Royal Fusiliers had been but little affected. The Usambara Valley along the Tanga-Moschi railway was also fairly free. On the big trek from Kilimanjaro to Morogoro the blackwater cases were almost entirely confined ...

... from television might help. You know that by means of the scanning disc, the picture is transformed into mere rapid fluctuations in the brightness of a beam of light. In a parallel manner, the focal plane of the Express Ray moves slowly through the object, progressively, dissolving layers of the thickness of a single atom, which are accurately reproduced at the other focus of the instrument—which ...

... anti-aphrodisiacal and Van Sweiten commenting upon that opinion, justly observes that the continual joltings caused by so violent an exercise, added to the compression produced upon the parts of generation by the weight of the body, was by no means unlikely to produce a focal relaxation of those organs to such an extent ...

... a moment, for three or four tiny ants rushed at each of the larger ones and began as thorough a cleaning as masseurs or Turkish-bath attendants. The three arrivals were at once hustled away to a distant part of the board and there cleaned from end to end. I found that the focal length of my 8-diameter lens was just out of reach of the ants, so I focused carefully on one of the soldiers and watched the entire process. The small ants scrubbed and scraped him with their jaws, licking him and removing ...

... that infinitely more is involved than the capture of a French town, or even the destruction of a French Army; it is a question of stamina; it is the climax of the world war, the focal point of the colossal struggle between the Latin and the Teuton, and on the battlefields of Verdun the gods will decide the destinies ...

... discuss these matters without going into a complete optical discussion. The radii of curvature of the surfaces, beginning with the first, i.e. the external face of the convex lens, are in the ratio of 1, 2, and 3; an allowance of 15 inches focal length per inch of aperture is reasonable (see Optics in Ency. Brit.), and the focal length is the same as the greatest radius of curvature. Thus, for an object glass 2 inches in diameter, the first surface ...

... precisely by the mean wave-length. This method is especially used with a so-called objective-grating, which consists of a series of metallic threads, stretched parallel to each other at equal intervals. On account of the diffraction of the light we now get in the focal plane of the objective, with the use of these gratings, not only a fainter image of the star at the place where it would have arisen without grating, but also at both sides of this image secondary ...

Only such trade routes could support such a city; only such trade routes give reason for the City's ...

... intended that the pictures taken are to be viewed by an instrument that requires their distance from the eyes to be less than the focal length of the lens used in their formation, what is the result? Why, that they subtend an angle larger than in nature, and are consequently apparently increased in bulk; and the obvious remedy is to increase the angle between the points of generation in the exact ratio as that ...

... from the elevated central point of view where we now stand, and in the focal light in which we now see, that no man can be justified before God upon the ground of personal character; for that character, when subjected to God's exhaustive scrutiny, withers and shrinks away. A man may possibly be just before his neighbor, or his friend, ...

... we may conclude that if an individual deviates at all from the path which the laws (or, directrix) indicate, if he does not show true respect to the decrees of the focal government, and preserve the true position between them, directly he is found deviating from his course, he is quickly banished to a less enlightened sphere. In an ellipse there is less likelihood of his straying away from the course which the directrix points out, ...

... two feet long. The problem then became that of seeing what you were doing, and one of the boys faked up a kind of binocular jeweler's loupe with long focus, so that I could lie back a yard from the screw and focus on it with about ten diameters magnification. The trouble was that the long focal length gave a field of vision about six times the diameter of the screw-head, which meant that every time my heart beat my head moved enough to throw the field of ...

... special lands were also stated in "the greate charter." At each of the four focal points of settlement—James City, Charles City, Henrico, and Kecoughtan, 3,000 acres were to be set aside as the company's land. Half-share tenants were to cultivate the lands and half of the company's profits was to be used to support several of the colonial officials. For the Governor, a ...

Dutton, of the U.S. Ordnance Corps.[5] The conclusions arrived at are;—that as regards the depth of the focal point, this is estimated at twelve miles, with a probable error of less than two miles; while, as regards the rate of travel of the earthquake-wave, the estimate is (in one case) about 3.236 miles per second; and in another ...

The tribes of the eastern United States had fixed and definitely bounded habitats, and their wanderings were in the nature of temporary excursions to established ...
