The rats who were being fed on milk from a London dairy came tumbling from their nest with an anxious hungry squeaking. They were getting thinner and thinner every day; in a few days they would be dead. But the old rat, whose diet was Grade A milk from the country, hardly took the trouble to move. He was as fat and sleek as a brown furry fruit, ripe to bursting. No skim and chalky water, no dried dung and tubercle bacilli for him. He was in clover. Next week, however, the fates were plotting to give him diabetes artificially. In their glass pagoda the little black axolotls crawled, the heraldry of Mexico, among a scanty herbage. The beetles, who had had their heads cut off and replaced by the heads of other beetles, darted uncertainly about, some obeying their heads, some their genital organs. A fifteen-year-old monkey, rejuvenated by the Steinach process, was discovered by the light of Lancing’s electric torch, shaking the bars that separated him from the green-furred, bald-rumped, bearded young beauty in the next cage. He was gnashing his teeth with thwarted passion. Lancing expounded to the visitors all the secrets. The vast, unbelievable, fantastic world opened out as he spoke. There were tropics, there were cold seas busy with living beings, there were forests full of horrible trees, silence and darkness. There were ferments and infinitesimal poisons floating in the air. There were leviathans suckling their young, there were flies and worms, there were men, living in cities, thinking, knowing good and evil. And all were changing continuously, moment by moment, and each remained all the time itself by virtue of some unimaginable enchantment. They were all alive. And on the other side of the courtyard beyond the shed in which the animals slept or uneasily stirred, in the huge hospital that went up sheer like a windowed cliff into the air, men and women were ceasing to be themselves, or were struggling to remain themselves. They were dying, they were struggling to live. The other windows looked on to the river. The lights of London Bridge were on the right, of Blackfriars to the left. On the opposite shore, St. Paul’s floated up as though self-supported in the moonlight. Like time the river flowed, silent and black. Gumbril and Mrs. Viveash leaned their elbows on the sill and looked out. Like time the river flowed, stanchlessly, as though from a wound in the world’s side. For a long time they were silent. They looked out, without speaking, across the flow of time, at the stars, at the human symbol hanging miraculously in the moonlight. Lancing had gone back to his German book; he had no time to waste looking out of windows. “To-morrow,” said Gumbril at last, meditatively. “To-morrow,” Mrs. Viveash interrupted him, “will be as awful as to-day.” She breathed it like a truth from beyond the grave prematurely revealed, expiringly from her death-bed within. “Come, come,” protested Gumbril.
