Of this plagueor, more properly, eruptive typhoid fever, distinct from, yet analogous to, the smallpoxa description no less clear than impressive has been left by the historian Thucydides, himself not only a spectator but a sufferer.

The age, if possible, should not be less than twenty nor exceed thirty years, with the health sound in every respect, and the body free from all eruptive disease or local blemish.

Hence the difficulty of breathing experienced after scalds or burns on the cuticle, the cough that follows the absorption of cold or damp by the skin, the oppressed and laborious breathing experienced by children in all eruptive diseases, while the rash is coming to the surface, and the hot, dry skin that always attends congestion of the lungs, and fever.

These are called Eruptive Fevers, and embrace chicken-pox, cow-pox, small-pox, scarlet fever, measles, milary fever, and erysipelas, or St. Anthony's fire.

A tunnel thirty miles in length was cut from a great lake nearly a thousand feet higher than the base of the volcano; and through this for a quarter of a year, say some six Terrestrial months, water was steadily poured into the subterrene cavities wherein the eruptive forces were generatedthe plutonic laboratory of the rebellious agency.

As the child grows older, the system of cleanliness must in no particular be relaxed, and it will be found the best preservative against those eruptive disorders which are so frequent and troublesome during the period of infancy.

It is frequently ordered, therefore, to be employed in eruptive fevers, as measles, scarlet fever, smallpox, and other fevers; and also in some local inflammations, particularly of the brain.

This disease, the most dreaded of all eruptive fevers, is not so commonly met with in the present day as formerly; thanks to that Providence which led to the discovery of Jenner.

NATURAL SMALL-POX.The infection of small-pox having been received into the system of a child that has not been vaccinated, fourteen days (on an average) will transpire before the commencement of the febrile symptoms, or eruptive fever.

As we proceeded eastward, the eruptive rocks became more numerous; chlorite slate, veins of quartz, chert, and variegated jasper, frequently forming the summits of the most elevated hills, while, on the general level of the plain, are occasionally found thin beds of ancient lava.

At their summits are deep fissures, the heat of the eruptive rocks from beneath having been sufficient to convert the trap and sandstone rocks into a deep bluish-grey scoria, having a specific gravity of nearly four; but we did not observe any instance of the actual overflow of lava, and consequently there was a want of the fertilising properties in the soil resulting from it that usually accompanies volcanic formations.

This is owing to the absence of actual lava, the eruptive heat having nearly been sufficient to convert the superincumbent primary and tertiary rocks into a vitreous scoria, having a specific gravity of 3.2, and is highly indestructible in its texture.

Even the colored chef de cuisine, a muscular mulatto, with a beard of a rash disposition, coming out on wrong parts of his face in little eruptive pustules of black wool, sported his lines out of the galley-airholes, and his porgies were simmering in the pan while their memories were yet green in the submarine parishes from which they came.

But hither come, on yon swoln arch to gaze, And view the vivid flash eruptive blare; Light those high walls with transitory gleam, Illume the air, and sparkle in the stream.

These are veins contained in the same sheet of eruptive rock, but the ores are as different as possible.

Thousands of mineral veins in this and other countries occur in regions remote from eruptive rocks.

Without this demonstration of the origin and antiquity of the gold, it might very well have been supposed to be derived from the eruptive rock.

Industrial eruptive diseases have to be dealt with in like fashion, the cause sought for, and the social remedy applied fearlessly.

The lecturer first showed a world chart showing distribution of volcanoes, showing general tendency of eruptive explosions to occur in lines.

The dip of the lavas on our Cape corresponds with that of the lavas of Inaccessible Island, and points to an eruptive centre to the south and not towards Erebus.

When we had hoisted it on board, a proceeding that required pretty strong tackle and several hands, it was flayed, yielding a hide of extraordinary thickness, lined on the inside with blubber, and scantily covered externally with short reddish brown hair, the greatest part of its skin appearing to have been denuded of this clothing by eruptive blotches, such as I presume disfigure a measly hog.

The rolling country east of this contained eruptive rocksa porphyritic disbase, with zeolite, quartz, and agate of Triassic age.

It is not improbable, however, that this term was applied to columns belonging to the trap formation, since no burning mountain has been any where observed on the coast of New Holland: nor do the drawings of Depuch Island, made on board Captain King's vessel, give reason to suppose that it is at present eruptive.

No eruptive mountains, nor any traces of recent volcanic eruption, have yet been observed in any part of Australia.

Infusions made from the fresh flowers are gently laxative and aperient; when dry, they are said to promote chiefly the cuticular excretion, and to be particularly serviceable in erysipetalous and eruptive disorders.
