I have no doubt that this upper layer originally existed as a bed of shells, like that on the eighty-five-feet ledge; but it does not now contain even a trace of organic structure. The powder has been analyzed for me by Mr. T. Reeks; it consists of sulphates and muriates both of lime and soda, with very little carbonate of lime.
These saline incrustations consist of carbonates and sulphates, with alkaline bases; and it is well known these act an important part in vegetation. The influence of lime in their production is manifested by their appearing first at the place where the mortar and brick come into contact.
The antidotes for poisoning by opium, or any of its preparations, as morphia, laudanum, &c., are the stomach pump if it can be had; tartar emetic, 2 to 5 grains, or sulphate of zinc, 15 to 30 grains, or sulphate of copper, 12 to 15 grs., for an adult. The sulphates of zinc or copper are best, because they act quicker.
As races and individual minds must always differ just as sulphates and carbonates do, I cannot see ground for expecting the Broad Church to be founded on any fusion of intellectual beliefs, which of course implies that those who hold the larger number of doctrines as essential shall come down to those who hold the smaller number.
The waters of the primordial ocean were probably highly charged with mineral matter, with various chlorides and sulphates and carbonates, such as the sulphate of soda, the sulphate of lime, the sulphate of magnesia, the chloride of sodium, and the like.
Many other minerals may be inclosed in limestones in small quantities, and an exact qualitative analysis will often show the presence of sulphides or sulphates, phosphates, and titanates, and the alkali or even the heavy metals. No attempt is made in the following procedures to provide a complete quantitative scheme which would take into account all of these constituents.
It is not isomorphous with the orthorhombic barium and strontium sulphates, as might be expected from the chemical formulae. Distinctly developed crystals are somewhat rare, the mineral usually presenting the form of cleavage masses. The hardness is 3-1/2 and the specific gravity 2.9. The colour is white, sometimes greyish, bluish or reddish.
We shall endeavor to show in that which follows, that copper, zinc, nickel, and cobalt, and even iron, manganese, cadmium, bismuth, and tin, whether they be present as sulphates, chlorides, or nitrates, may be precipitated and separated from each other by electrolytic methods much more rapidly than by any previously known process.
It is insoluble in water, is powerfully electromotive, and is most strikingly energetic in numerous chemical agencies, its action on nearly all metallic bodies being to carry them at once to the state of peroxide, or to their highest point of oxidation; it changes sulphurets into sulphates, instantaneously destroys several gaseous compounds, and bleaches indigo, thus shewing its analogy with chlorine.
There are springs bubbling and steeping and stagnating by the wayside; springs containing carbonates of soda, lithia, lime, magnesia, and iron; sulphates of potassa and soda, chloride of sodium and silica, in various solutions. Some of these are sweeter than honey in the honeycomb; some of them smell to heaven what more can the pampered palate of man desire?
