    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1825 Excerpt: ...near its surface, forming vesicular cavities, the size, number, and sphericity of which, will be proportioned to the specific gravity, and fineness of grain. Where these are at their maximum, large cavernous blisters may be formed, such as occur in the lavas of Iceland, Bourbon, Lanzarote, &c. Some of them will burst, and allow the escape of the steam through the aperture, previous to the consolidation of the entire surface, but after the process had sufficiently taken place to prevent the falling in of the sides when the elastic fluid has escaped. The walls of these cavities, both on a small and large scale, exhibit in general the traces of a certain degree of superficial fusion, in a glassy varnish which appears to be more or less remarkable, in proportion to the fineness of the grain, and the size of the vesicles. The same kind of glazing appears on the exposed surface of the lava when rapidly consolidated. It may be accounted for perhaps by the consideration that the instantaneous vaporization and expansion of all the water contained in the superficial pellicle of lava, suddenly lowers its temperature at the moment of its solidification. In the next moment, therefore, the equilibrium will be restored, by the rapid transmission of caloric from the intensely heated lava immediately beneath, which must act upon the superficial pellicle, in the same manner as an increase of temperature produced in any other mode, and occasion its partial fusion; which will be the more easily accomplished in proportion to the fineness of its grain. When the vesicular cavities are large, pseudo-stalactitic J Protuberances of lava will form upon its upper and lower suraces, by means of the tenacity of the mass as it is forced asunder; and if the lava contain solid crystals.
