The magnification was increased till cities were no longer blurs, but truly cities.
Quickly the view singled out a single apartment, and the great smooth roof was enlarged on the screen to the absolute maximum clarity, till further magnification simply resulted in worse stratospheric distortion.
These cells are completely filled with their large, round nuclei, so that the wall has the appearance, under higher magnification than is used in this figure, of a band of closely strung, round beads.
These folds, even under the low magnification used, are more evident than is shown in the present figure.
With the low magnification used these details could not, of course, be shown.
A transverse groove near the anterior end of the lower jaw marks off the tongue, tn; and the rudiments of teeth are seen but not shown in the figure because of the low magnification used.
As has been said, the oesophagus here has no lumen, and when examined under high magnification its walls are found to be completely fused, not merely in close contact.
With the greatest magnification we can produce, the Martian limb still appears perfectly smooth.
It has been supposed that improved atmospheric conditions simply amount to bringing the object nearer by permitting greater magnification without altering the hazy look of its detail.
Such slenderness at the then distance of Mars would correspond, under the magnification commonly used, only to three quarters of a mile.
We are not so near it as we could wish; for on these occasions even at their best it is over two hundred times as distant as the moon and the greatest magnification possible still leaves it a hundred thousand miles away.
The magnification was reduced a little, a card was moved into the picture, and it was stepped up again.
Even with the high degree of magnification possible with the microgrid screen, we can't bring out the individual ridges, but the pattern is unmistakable.
Rush an individual picture of each one, maximum magnification consistent with clarity, to Dhergabar Equivalent to be transposed to Home Time Line.
Rex calls attention to the fact that under low magnification the spores appear spotted; but the spots are occasioned simply by the closer aggregation, at particular points, of the ordinary papillae.
Only under a moderate magnificationdo the citrine tints come out.
It is so delicate that it is difficult to see even in well-stained preparations; a high magnification and careful focusing are, therefore, required.
The degree of magnification should always be expressed in diameters, not times, which is a misleading term.
He decreased the magnification of Hot Rod so that the entire project showed.
You say we're beyond themagnification range of the telectroscope.
He increased the magnification to maximum, and the four men looked eagerly at the system.
When the crew starts actual operation, we will turn on the magnificationscreens and get some close-up views of the process.
He cut the magnification again at fifty and at thirty and at ten.
At full magnification he could see where forests had been cut away in wedges and half-squares, with clear spaces between them.
But there was ten times the magnification one would expect from the Moon; and I calculated that those sound-waves were shifted somewhere.
With the immense magnification necessary for transmitting from the Moon, such deflection might be construed as a mere fan-like extension.
A trial will show that we have considerably increased the magnificationbut decreased the amount of light admitted by the lens, therefore we shall probably require an exposure as long as an hour.
When our slide is prepared, with a magnification of at least one thousand diameters, we may reasonably hope that our trouble will be rewarded.
Each plant measures about five thousandths of an inch in length, so we shall require a highmagnification to examine it.
We repeat again, increase your magnification always, when possible, by using higher power objectives rather than eyepieces with greater magnifying powers.
We may make a beginning by examining his back under a low magnification and observing that it is protected by a number of hard plates which form a very efficient armour.
With a lens of such a focal length we shall require a camera with very long bellows to obtain much magnification of our object but, if our camera is one with only short bellows, we can still overcome our difficulties.
The larger, lower lens is known as the field or collecting glass; it renders the image clearer though, in so doing, it reduces the magnification of the eyeglass.
A higher magnification will show that each scale is roughly flask-shaped, and that its narrow end fits into a little socket in the wing proper.
To find the magnification possible with our camera and lens, extend the camera bellows to the full and set up a foot rule in front of the lens.
A careful examination of our object with a fairly high magnification will show that, though the scraping was very gentle and quite painless, something has been removed from the mouth.
A high magnification will show that the stinging hair of the nettle is not quite so simple as it appears at first sight.
Its name is Euglena Viridis and we require our highest magnification to examine it for it does not exceed one-two hundred and fiftieth part of an inch in length.
With this objective in an ordinary microscope the magnificationwould be about thirty diameters.
In this case, however, under a high magnification we shall notice that the fibres are marked with a number of very fine lines running lengthways, whilst every now and then there are fairly deep indentations.
The official pilot used an electron camera, giving a complete and overlapping series of pictures of the shore five miles away with incredible magnification and detail.
And only an electron camera could have used enough magnification to show one man laughing, as if at something the other had said.
The Watchung ridges extend only about eight miles northward of the Paterson gaps, but reach thirty miles southwestward.
They approached within hail, and were understood, through the aid of the Kariak interpreters on board the Gabriel, to enquire whence the vessel came and what was the object of the expedition in entering these waters.
At the top of the map the supposed Paris meridians[6] are indicated, a difference between Paris and Tobolsk being assumed of 70° degrees, which is about five degrees too much.
The essay is published in the Proceedings of the Boston Society of Natural History, 1889.
Those are the scales," replied Thorndyke, "that shows the degree ofmagnification or reduction.
Adjusted magnification defined the vehicles as personnel carriers, flatbed trailers, dome fissure-fusers, and methane frost scrapers.
