He agrees in the main with Niecks, that certain of these compositions were written at Valdemosa Nos. 4, 6, 9, 13, 20 and 21 and that "Chopin, having sketches of others with him, completed the whole there, and published them under one opus number. ... The atmosphere of those I have named is morbid and azotic; to them there clings a faint flavor of disease, a something which is overripe in its lusciousness and febrile in its passion.
Now, Harding having sulphuric acid at his disposal, had already been easily able to produce azotic acid by attacking the saltpeter with which nature supplied him.
On the other hand, the advantages of pyroxyle consist in this, that it is not injured by damp, that it does not make the gun-barrels dirty, and that its force is four times that of ordinary powder. To make pyroxyle, the cotton must be immersed in the fuming azotic acid for a quarter of an hour, then washed in cold water and dried. Nothing could be more simple.
The presence of phosphatic nodules and bituminous matter, even in some of the lowest azotic rocks, probably indicates life at these periods; and the existence of the Eozoon in the Laurentian formation of Canada is generally admitted. There are three great series of strata beneath the Silurian system in Canada, in the lowest of which the Eozoon is found.
I could, perhaps, show chymically how the atmosphere of the closed rooms becomes thus azotic, but I prefer to submit to the test of your senses. The shawl shall be ordered on, since you will risk it. Yes, go to the races, and appear to be amused. Be more social. Washington, December 9, 1803.
The other substances, azotic acid and potash, were all at his disposal. The way in which the battery was composed was as follows, and the results were to be attained by the reaction of acid and potash on each other. A number of glass bottles were made and filled with azotic acid.

Cyrus Harding could have manufactured this substance by treating the carbonate of potash, which would be easily extracted from the cinders of the vegetables, by azotic acid. But this acid was wanting, and he would have been in some difficulty, if nature had not happily furnished the saltpeter, without giving them any other trouble than that of picking it up.
This taste is caused by the azotic acid formed from the oxygen and azote of the atmosphere.
In default of fulminate, he could easily obtain a substance similar to guncotton, since he had azotic acid at his disposal. This substance, pressed in a cartridge, and introduced among the nitro-glycerine, would burst by means of a fuse, and cause the explosion. But Cyrus Harding knew that nitro-glycerine would explode by a shock.
