The greater part of it is taken up with a semi-fluid, transparent gelatinous substance, the corpus vitreum. It is a lenticular, bi-convex, transparent body, the most important of the refractive media in the eye.
But beyond that indescribable and incomprehensible vacuum they saw faint lenticular bodies of light, which were also named, and which each man knew to be other galaxies, charted and named by the almost unlimited power of the Fenachrone astronomers, but not as yet explored.
In a fermentation of glycerine in a mineral medium the glycerine was fermenting under the influence of butyric vibrios after we had determined the, we may say, exclusive presence of lenticular vibrios, with refractive corpuscles, we observed the fermentation, which for some unknown reason had been very languid, suddenly become extremely active, but now through the influence of the ordinary vibrios.
And I have sometimes for Tryals sake brought in by a Lenticular Glass, the Image of a River, Shin'd upon by the Sun, into an Upper Room Darkn'd, and Distant about a Quarter of a Mile from the River, by which means the Numerous Declining Surfaces of the Water appear'd so Contracted, that upon the Body that receiv'd the Images, the whole River appear'd a very White Object at two or three paces distance.
When the image is produced by means of a lenticular glass, the place it occupies will be found in the prolongation of the line that extends from the object to the centre of the lens.
"Put your back against the wall," continued Prudent, "and you, Evans, get on his shoulders while I buttress him up." "Right!" said Evans. An instant afterwards his knees were on Frycollin's shoulders, and his eyes were level with the window. The window was not of lenticular glass like those on shipboard, but was a simple flat pane.
It probably facilitated the rupture of the earth and the formation of the gulf of Cariaco. This clay is of a smoky colour, impregnated with petroleum, mingled with lamellar and lenticular gypsum and sometimes traversed by small veins of fibrous gypsum. It incloses angular and less friable masses of dark brown clay with a slaty and sometimes conchoidal fracture.
The atmosphere possesses also a reflecting and refracting power, arising from its varying density, and, perhaps, in the latter case, somewhat from its lenticular outline. But for this property we should have no twilight.
After suggesting that the refraction of the rays in the atmosphere may be due to what he calls its 'lenticular outline, he defines refraction to be 'the bending of a ray passing obliquely from a rarer into a denser medium, a good enough popular definition, but for its sad defectiveness.
Sheets of quartzose matter, chiefly lenticular and conforming to the bedding of the inclosing rocks, but sometimes filling irregular fractures across such bedding, found only in metamorphic rocks, limited in extent laterally and vertically, and consisting of material indigenous to the strata in which they occur, separated in the process of metamorphism, e.g., quartz ledges carrying gold, copper, iron pyrites, etc., in the Alleghany Mountains, New England, Canada, etc.
