This residual gas which is so lacking in chemical afFmity is an element called nitrogen. Like sulphur, however, its lack of affinity is due rather to lack of the right conditions for combina- tion than to absence of that power. In nature, nitrogen occurs very abundantly in combination with other ele- ments, and some of its compounds form important parts of our body material, notably muscle or flesh. Owing to the weakness of its affinity for most elements its compounds are apt to break up readily, and on that account are spoken of as un- stable compounds. Most of our explosives, such as gunpowder and <f ^ nitroglycerine, owe their explosive power to the fact that they are unstable compounds of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Eddy, Walter Hollis, b. 1877.
