The heavy cruiser Chicago hung motionless in space, thousands of miles distant from the warring fleets of space-ships so viciously attacking and so stubbornly defending the planetoid of the enemy. In the captain's sanctum Lyman Cleveland crouched tensely above his ultra-cameras, his sensitive fingers touching lightly their micrometric dials. His body was rigid, his face was set and drawn.
Lowell's associates in the observations of 1894 at Flagstaff, Arizona, observed what he believed to be a cloud over the unilluminated part of Mars's disk, which, by micrometric measurement and estimate, was drifting at an elevation of about fifteen miles above the surface of the planet.
If a star is approaching, its spectral lines are shifted toward the violet end of the spectrum by an amount depending upon the velocity of approach; if it is receding, the lines are correspondingly shifted toward the red end. Spectroscopic observation, then, combined with micrometric measurements of the cross motion, enables us to detect the real movement of the star in space.
Very attractive looking her, too dark hair and eyes, rather long-oval features, clear, lightly tanned complexion, bright red lipstick put on with a micrometric exactitude that any engineer could appreciate.
These instrumental defects may be too small to be detected in ordinary micrometric or photographic observations, and still sufficient to affect the photographs just described. A method of enlargement has been tried which gives very satisfactory results, and removes the lines above mentioned as defects in the negatives.
Except when he emptied it of ashes and refilled it, it was a permanent fixture of his weather-beaten face. Trehearne was somewhat shorter, and fair; his sandy mustache, beginning to turn gray at the edges, was clipped to micrometric exactness. They shook hands with Rand, who set Hester back in her place. Trehearne took the matchlock out of Pierre's hands and looked at it wistfully.
The river Metis and its branch, the Mistigougeche, were surveyed by an azimuth compass of Smallcaldus construction, and the distances measured by a micrometric telescope by Ertil, of Munich. The courses of the rest of the lines were determined by compasses of similar construction, and the distances measured by chains of 100 feet constructed by Dollond, of London, and Brown, of New York.
"You see my new road and the key to my intentions?" said the Major, forgetting all about his witch, and flourishing his geological hammer, while standing thus at his "nucleus." "To understand all, you have only to stand here. You see those leveling posts, adjusted with scientific accuracy. You see all those angles, calculated with micrometric precision. You see how the curves are radiated "
Yet, from the same, Colonel Tupman deduced 8·81", implying a distance 700,000 miles greater than Stone had obtained. The best French observations of contacts gave a parallax of about 8·88"; French micrometric measures the obviously exaggerated one of 9·05". Photography, as practised by most of the European parties, was a total failure.
