To quickly assess the difficulty of the text, read a short excerpt:
Pyrene, Cio H2, a white crystalline solid, is associated with the foregoing, than which it is more fusible.
When tar is distilled, a semi-solid mass is left in the still. When the distillate is rectified, a solid pitch or bitumen remains ; these are utilized for various pur- poses.
The carbonaceous mass left at the first distillation, is mixed with the ammoniacal water, and forms a good manure. The tarry residuum of the second distillation is used as asphalt is, for coatings.
There appear to be... varieties of coal, which, whether produced by diflferences in the vegetable species originally composing them, or by different conditions of decomposi- tion, produce different reactions when subjected to dry 72 SLOW DECOMPOSITION OF COAL.
distillation. It is notorious to practical men, that certain coals yield paraffine at lower temperatures than others, and that some^ coals produce naphthalin at temperatures which only aid in forming paraffine in the rest.
When the order of decomposition of an organic suh^ stance is spoken of, it must be understood only as referring to the exact condition under which it takes place ; for under diflferent conditions, a different order of decomposi- tion takes place, and a new set of products are the result : for example, it is usual to speak of coal, that when sub- jected to a low degree of heat, it decomposes so as to form inelastic or condensible vapors, while, if the heat be augmented, elastic or gaseous products will form ; but this is only true of the conditions under which the coal has been treated in that experiment ; for, on the large scale, in the operations of nature, we do not find such results to ensue.
