This is a grand conception, and occasioned the publication of many similar stories.

"You will conceive a bunch of grapes," said he, "which are covered by some infinitesimal but noxious bacillus. The gardener passes it through a disinfecting medium. It may be that he desires his grapes to be cleaner. It may be that he needs space to breed some fresh bacillus less noxious than the last. He dips it into the poison and they are gone. Our Gardener is, in my opinion, about to dip the solar system, and the human bacillus will in an instant be sterilized out of existence."

Again there was silence. It was broken by the high trill of the telephone-bell.

"There is one of our bacilli squeaking for help," said he with a grim smile. "They are beginning to realize that their continued existence is not really one of the necessities of the universe."

He was gone from the room for a minute or two. I remember that none of us spoke in his absence. The situation seemed beyond all words or comments.

"The medical officer of health for Brighton," said he when he returned. "The symptoms are for some reason developing more rapidly upon the sea level. Our seven hundred feet of elevation give us an advantage

Was this just the product of Doyle's prodigious imagination? Or had scientists described a similar phenomenon?

Where did Doyle get his ideas about enormous gas clouds in local space? It's possible that he read the works of Edward Emerson Barnard (1857-1923), who was an American astronomer renowned for his extensive work in observational astronomy, particularly in the study of dark nebulae, comets, and the Milky Way's structure.

From around 1889, Barnard pioneered deep photography of the sky, finding many 'holes in the Milky Way'. At first he compared them to sunspots, but by 1899 was prepared to write: "One can scarcely conceive a vacancy with holes in it, unless there is nebulous matter covering these apparently vacant places in which holes might occur". These holes are now known as dark nebulae. The first direct detection of cold diffuse matter in interstellar space came in 1904, when Johannes Hartmann observed the binary star Mintaka and deduced that a cloud of interstellar matter must lie in his line of sight to the star.

In 1919, Barnard published "A Photographic Atlas of Selected Regions of the Milky Way," which included 349 dark nebulae, now known as Barnard Objects or B (Barnard) numbers. However, his first significant publication on dark nebulae came in 1913 with his paper titled "Dark Regions in the Sky Suggesting an Obscuration of Light," which appeared in the Astrophysical Journal (read the preface to his Atlas).

There was an earlier news event that might also have prompted his story, about Halley's Comet, which appeared in 1910. French astronomer Camille Flammarion speculated in the media that cyanogen gas in the comet's tail could "impregnate the atmosphere and possibly snuff out all life on the planet" if Earth passed through it. Some newspapers added that maybe acetylene gas might be involved, creating a panic.

I should also point out an even earlier story. In "The Purple Cloud" (1901) MP Shiel describes an arctic explorer who somehow inadvertently releases a vast cloud of toxic cyanide gas that destroys civilization:

"The dust, though very thin and flighty above-decks, lay thickly deposited below, and after having made a tour of investigation throughout the ship, the first thing which I did was to examine that—though I had tasted nothing all day, and was exhausted to death. I found my own microscope where I had left it in the box in my berth to starboard, though I had to lift up Egan to get at it, and to step over Lamburn to enter the chart-room; but there, toward evening, I sat at the table and bent to see if I could make anything of the dust, while it seemed to me as if all the myriad spirits of men that have sojourned on the earth, and angel and devil, and all Time and all Eternity, hung silent round for my decision; and such an ague had me, that for a long time my wandering finger-tips, all ataxic with agitation, eluded every delicate effort which I made, and I could nothing do. Of course, I know that an odour of peach-blossom in the air, resulting in death, could only be associated with some vaporous effluvium of cyanogen, or of hydrocyanic ('prussic') acid, or of both; and when I at last managed to examine some of the dust under the microscope, I was not therefore surprised to find, among the general mass of purplish ash, a number of bright-yellow particles, which could only be minute crystals of potassic ferrocyanide.

('The Purple Cloud' (1901) by MP Shiel)

What potassic ferrocyanide was doing on board the Boreal I did not know, and I had neither the means, nor the force of mind, alas! to dive then further into the mystery; I understood only that by some extraordinary means the air of the region just south of the Polar environ had been impregnated with a vapour which was either cyanogen, or some product of cyanogen; also, that this deadly vapour, which is very soluble, had by now either been dissolved by the sea, or else dispersed into space (probably the latter), leaving only its faint after-perfume; and seeing this, I let my poor abandoned head drop again on the table, and long hours I sat there staring mad, for I had a suspicion, my God, and a fear, in my breast.
