Not illustrated. 1857 Excerpt: ...and awfully as the fragment of the boiler, an outline of which is shown by Fig. 172. This was thrown through the roof of the smiths' shop, and then lodged on the roof of the paint shop, at the distance of about 200 feet from its starting point.' FIG. 172. Its length was 15 feet, and its weight 1,220 pounds. The smooth, round aperture was the place of admission into the boiler, having had a plate of iron opening on the inside as a door. Force of the Steam.--Perhaps there is no instance on record where the power of steam from a boiler of the same dimensions, has been equal to that here described; and it is difficult for any one, even after reviewing the consequences as we did, to conceive how it could have been possible that the quantity of steam contained in that boiler could have produced such tremendous effects. Indeed, had the whole space been filled with gun-powder, and this exploded in an anstant, it is not probable that the consequences, with respect to mechanical force, would have been so terrible as those here exhibited. Remarks.--Having thus shown the student how stationary steam-hoilers are constructed, together with sufficient proofs of the tremendous power of confined steam, we find that the space allotted to this subject has already been occupied, and we can only add, that after a careful examination of the remains of the boiler, our theory of the cause of the explosion is the spheroidal state of the water, induced by over-heating of the boiler, and its being suddenly cooled by the admission of a large quantity of water. A statement of this theory is contained under " Globular or Spheroidal state of Water." (673.) DISTILLATION. 696. This process is employed for the separation of a volatile substance, from another less volatile, by mean...
