What I read in the Times was not very definite, for how could it be? but in the main it confirmed inferences which I had myself drawn, and fairly satisfied my mind.
There had been a battle royal in the paper between my old collaborator Professor Stanistreet and Dr. Martin Rogers, and never could I have conceived such an indecorous piece of business, men like them calling one another “tyro,” “dreamer,” and in one place “blockhead.” Stanistreet denied that the perfumed odour of almonds attributed to the advancing cloud could be due to anything but the excited fancy of the reporting fugitives, because, said he, it was unknown that either Cn, HCn, or K4FeCn6 had been given out by volcanoes, and the destructiveness to life of the travelling cloud could only be owing to CO and CO2. To this Rogers, in an article characterised by extraordinary heat, replied that he could not understand how even a “tyro”(!) in chemical and geological phenomena would venture to rush into print with the statement that HCn had not commonly been given out by volcanoes: that it had been, he said, was perfectly certain; though whether it had been or not could not affect the decision of a reasoning mind as to whether it was being: for that cyanogen, as a matter of fact, was not rare in nature, though not directly occurring, being one of the products of the common distillation of pit-coal, and found in roots, peaches, almonds, and many tropical flora; also that it had been actually pointed out as probable by more than one thinker that some salt or salts of Cn, the potassic, or the potassic ferrocyanide, or both, must exist in considerable stores in the earth at volcanic depths. In reply to this, Stanistreet in a two-column article used the word “dreamer,” and Rogers, when Berlin had been already silenced, finally replied with his amazing “blockhead.” But, in my opinion, by far the most learned and lucid of the scientific dicta was from the rather unexpected source of Sloggett, of the Dublin Science and Art Department: he, without fuss, accepted the statements of the fugitive eyewitnesses, down to the assertion that the cloud, as it rolled travelling, seemed mixed from its base to the clouds with languid tongues of purple flame, rose-coloured at their edges. This, Sloggett explained, was the characteristic flame of both cyanogen and hydrocyanic acid vapour, which, being inflammable, may have become locally ignited in the passage over cities, and only burned in that limited and languid way on account of the ponderous volumes of carbonic anhydride with which they must, of course, be mixed: the dark empurpled colour was due to the presence of large quantities of the scoriae of the trappean rocks: basalts, green-stone, trachytes, and the various porphyries. This article was most remarkable for its clear divination, because written so early—not long, in fact, after the cessation of telegraphic communication with Australia and China; and at a date so early Sloggett stated that the character
