The protoplasm of Algae and Fungi becomes, under many circumstances, partially, or completely, freed from its woody case, and exhibits movements of its whole mass, or is propelled by the contractility of one, or more, hair-like prolongations of its body, which are called vibratile cilia.
S. Ramon y Cajal to follow up the investigation by means of an improved application of Golgi's method of staining, and to demonstrate that the axis cylinders, together with all their collateral branches, though sometimes extending to a great distance, yet finally terminate, like the other cell prolongations, in arborescent fibrils having free extremities.
Where, as among the compound Hydrozoa, there is a union of many such primitive groups as form Hydræ; or where, as in a Medusa, one of these groups has become of great size; there exist rude channels running throughout the substance of the body: not, however, channels for the conveyance of prepared nutriment, but mere prolongations of the digestive cavity, through which the crude chyle-aqueous fluid reaches the remoter parts, and is moved backwards and forwards by the creature's contractions.
The only bond between these three stories is, so to speak, geographical, for their scene, be it land, be it sea, is situated in the same region which may be called the region of the Indian Ocean with its off-shoots and prolongations north of the equator even as far as the Gulf of Siam.
From the medullary substance proceed certain cords or prolongations, termed 'nerves', by which the animal is enabled to receive impressions from surrounding objects and to connect himself with them, and also to possess many pleasurable or painful sensations.
The most desperate and extensive strike that had yet occurred in this country was that of 1877, by the employees of the principal railway trunk lines, the Baltimore and Ohio, the Pennsylvania, the Erie, the New York Central, and their western prolongations. At a preconcerted time junctions and other main points were seized.
Hence, too, the doctrine of freedom: the images that appear in such a day-dream are often congruous in character with those that preceded, and mere prolongations of them; but this prolongation itself modifies them, and what develops is in no way deducible or predictable out of what exists. This situation is perfectly explicable scientifically.
This bounty, which, like most others, was granted only for a limited time, was continued by several prolongations, but was reduced to 4d. the pound. It was allowed to expire with the end of the session of parliament which followed the 25th March 1781. Geo. III. chap. 26, upon the importation of hemp, or undressed flax, from the British plantations.
The scar becomes more and more conspicuous, is elevated above the surface, of a pinkish or brownish-pink pink colour, and sends out irregular prolongations around its margins. The patient may complain of itching and burning, and of great sensitiveness of the scar, even to contact with the clothing.
They are rarely provided with a definite capsule, and frequently send prolongations of their substance between and into muscles and other structures in their vicinity. They are of congenital origin and usually make their appearance at or shortly after birth.
