And the bubbles of light again rose and fell, and in their disordered, irregular, turbulent maze, mingled with the wan moonlight. And now from these globules themselves as from the shell of an egg, monstrous things burst out; the air grew filled with them; larvae so bloodless and so hideous that I can in no way describe them except to remind the reader of the swarming life which the solar microscope brings before his eyes in a drop of water - things transparent, supple, agile, chasing each other, devouring each other - forms like nought ever beheld by the naked eye. As the shapes were without symmetry, so their movements were without order. In their very vagrancies there was no sport; they came round me and round, thicker and faster and swifter, swarming over my head, crawling over my right arm, which was outstretched in involuntary command against all evil beings.
