309 examples of sacs in sentences
The yeast plant is a mere sac, or "cell," containing a semi-fluid matter, and Schwann's microscopic analysis resolved all living organisms, in the long run, into an aggregation of such sacs or cells, variously modified; and tended to show, that all, whatever their ultimate complication, begin their existence in the condition of such simple cells.
In favourable specimens, again, almost the whole ground substance appears to be made up of similar bodiesmore or less carbonized or blackened and, in these, there can be no doubt that, with the exception of patches of mineral charcoal, here and there, the whole mass of the coal is made up of an accumulation of the larger and of the smaller sacs.
The latter appears to rise out of the former, by the breaking-up and increasing carbonization of the larger and the smaller sacs.
It is now thirty-four years since he carefully described and figured the coin-shaped bodies, or larger sacs, as I have called them, in a note appended to the famous paper "On the Coalbrookdale Coal-Field," published at that time, by the present President of the Geological Society, Mr. Prestwich.
But discovery sometimes makes a long halt; and it is only a few years since Mr. Carruthers determined the plant (or rather one of the plants) which produces these spore-cases, by finding the discoidal sacs still adherent to the leaves of the fossilized cone which produced them.
These conical fruits, however, did not produce seeds; but the leaves of which they were composed bore upon their surfaces sacs full of spores or sporangia, such as those one sees on the under surface of a bracken leaf.
Now, it is these sporangia of the Lepidodendroid plant Flemingites which were identified by Mr. Carruthers with the free sporangia described by Professor Morris, which are the same as the large sacs of which I have spoken.
And, more than this, there is no doubt that the small sacs are the spores, which were originally contained in the sporangia.
Thus, the singular conclusion is forced upon us, that the greater and the smaller sacs of the "Better-Bed" and other coals, in which the primitive structure is well preserved, are simply the sporangia and spores of certain plants, many of which were closely allied to the existing club- mosses.
But this explanation is at once shown to be untenable when the smaller and the larger sacs are proved to be spores or sporangia.
The ends of the branches dilate and become closed sacs, which eventually drop off as spores.
A, diagrammatic representation of the ending of a bronchial tube in air sacs or alveoli; B, termination of two bronchial tubes in enlargement beset with air sacs (Huxley); C, diagrammatic view of an air sac. a lies within sac and points to epithelium lining wall; b, partition between two adjacent sacs, in which run capillaries; c, elastic connective tissue (Huxley).

These lie parallel in the medullary or central structure, but On reaching the cortical or outer layer, they wind about and interlace, ending, at last, in dilated closed sacs called Malpighian capsules.
The serous membranes form shut sacs, of which one portion is applied to the walls of the cavity which it lines; the other is reflected over the surface of the organ or organs contained in the cavity.

A large force of volunteers was again called out, but in the first encounter the whites were beaten, which success encouraged the Sacs and Foxes so much that they spread themselves over the whole of the country between the Mississippi and the Lake, and kept up a desultory warfare for three or four months against the volunteer troops.
This defeat entirely broke the power of the Sacs and Foxes, and they sued for peace.
This extends below the facets uniting the navicular to the pedal bone, and offers for consideration two sacs.
It follows, therefore, that the hair follicles, really depressions or cul-de-sacs of the skin itself, are lined by epithelial cells and connective tissue.
He mentions the town of the Sacs, on the Wisconsin, as the largest and best built he saw, "composed of ninety houses, each large enough for several families.
Northward of this scanty people lived the Sacs and Foxes, and around the upper Great Lakes the numerous and powerful Pottawattamies, Ottawas, and Chippewas; fierce and treacherous warriors, who did not till the soil, and were hunters and fishers only, more savage even than the tribes that lay southeast of them.
This blending of the actual and the figurative is seen in the description of the King and Emperor in Éviradnus: Leurs deux figures sont lugubrement grandies Par de rouges reflets de sacs et d'incendies. * *
