If you pass the same carbonic acid over the very quicklime thus obtained, you will obtain carbonate of lime again; but it will not be calc-spar, nor anything like it. Can it, therefore, be said that chemical analysis teaches nothing about the chemical composition of calc-spar?
I am afraid as the evenings get shorter, Mr Arabin, you'll find the reading desk too dark. I must send a fellow with an axe and make him lop off some of those branches. Mr Arabin declared that the morning light at any rate was perfect, and deprecated any interference with the lime trees.
I procured a more quiet horse, and we proceeded at a parson’s trot, and did ample honour to our feast, for we were very hungry on our arrival.” In our ride I found the country in this part of Cuba highly cultivated. Large patches of sugar-canes, cocoa, orange and lime groves met my eye in every direction, and in some places near lagoons or pieces of water rice was cultivated.
Thus, what we call limestone is a more or less pure calcareous earth in combination with a delicate acid, which is familiar to us in the form of a gas. Now, if we place a piece of this stone in diluted sulphuric acid, this will take possession of the lime, and appear with it in the form of gypsum, the gaseous acid at the same time going off in vapor.
They have invisible pockets in which they carry away all the more soluble parts, such as lime, soda, potash, silica, magnesia, and others, and leave for the land the more insoluble parts. These, too, in times of flood they carry away in suspension, in the shape of sand, silt, mud, gravel, and the like.
It is the arteries especially, and sometimes the muscles, which take this great liberty, and it is not unusual among old people to meet with these fairly ossified that is to say, changed into bone, thanks to the phosphate of lime with which they have consented to burden themselves. This is a third exception, and I will spare you any others. What may we infer from all this, my dear child?
A suggestion which may naturally enough present itself is, that these curious bodies are the result of some process of aggregation which has taken place in the carbonate of lime; that, just as in winter, the rime on our windows simulates the most delicate and elegantly arborescent foliage proving that the mere mineral water may, under certain conditions, assume the outward form of organic bodies so this mineral substance, carbonate of lime, hidden away in the bowels of the earth, has taken the shape of these chambered bodies.
The body is kept over one night, and in the case of great personages, for three days, or until the coffin a large log split in halves and hollowed out is prepared. When this is ready the body is placed in it, together with some prized articles of the deceased. After the top has been fitted to the lower portion, they are lashed together and the cracks are filled with lime.
Combinations of tallow, resin, and tar mineral and pine are patented mostly to use over other paints. Coal tar, sulphur, lime, and tallow, are the subject of one patent; guano, red lead, and oil of another; while sulphur and silica are claimed by a third. Paints containing mercury, arsenic, and even strychnine, are the subjects of several patents.
Air-slacked lime is also useful to the peach in small quantities; and so, no doubt, would be a little salt from time to time. Bone-meal is highly recommended. Like other fruit-trees, the peach does not thrive on low, wet ground, and the fruit-buds are much more apt to be winter-killed in such localities. A light, warm soil is regarded as the most favorable.
