Abstract
IN a very able and courteous review of my “Textbook of Inorganic Chemistry” which appeared in NATURE of April 14, “A. J. A.” makes two statements which I think might be misleading to many readers. He states that “in practice calcium cyanamide is not produced in an arc furnace”. The Stockholms Superfosfat Fabriks Aktiebolag, Stockholm, make 20,000 tons of cyanamide annually in arc furnaces, and since this modern so-called “continuous cyanamide process” is referred to most respectfully in the report of the Nitrogen Products Committee, I thought it worthy of mention—in an imperfect manner, it is true. It is quite possible that of the two cells described for the manufacture of electrolytic alkali, one is “obsolete” and the other “obsolescent”. It is five years since I saw one described in some text-books as “quite obsolete” operating with great activity; doubtless it has now gone out of use. Since these two cells, however, were the only ones I could find authoritatively described as in use, or as having been in use, in this country, I preferred to describe them rather than cells existing only in patent specifications.
