Daniel ran out and sacked an ant-nest. He returned in triumph carrying the nucleus of an anthill on the flat of a shovel. In the front room Wilkins had begun dictating, and Charles Comstock scribbling, a letter back to the King-not the substantive part (as they didn’t have an answer yet), but the lengthy paragraphs of apologies and profuse flattery that had to open it: “With your brilliance you illuminate the places that have long, er, languished in, er-”

“Sounds more like a Sun King allusion, Reverend,” Charles warned him.

“Strike it, then! Sharp lad. Read the entire mess back to me.”

Daniel slowed before the door to Hooke’s laboratory, gathering his courage to knock. But Hooke had heard him approaching, and opened it for him. With an outstretched hand he beckoned Daniel in, and aimed him at a profoundly stained table, cleared for action. Daniel entered the room, upended the ant-nest, set the shovel down, and only then worked up the courage to inhale. Hooke’s laboratory didn’t smell as bad as he’d always assumed it would.

Hooke ran his hands back through his hair, pulling it away from his face, and tied it back behind his neck with a wisp of twine. Daniel was perpetually surprised that Hooke was only ten years older than he. Hooke just turned thirty a few weeks ago, in June, at about the same time that Daniel and Isaac had fled plaguey Cambridge for their respective homes.

Hooke was now staring at the mound of living dirt on his tabletop. His eyes were always focused on a narrow target, as if he peered out at the world through a hollow reed. When he was out in the broad world, or even in the house’s front room, that seemed strange, but it made sense when he was looking at a small world on a tabletop-ants scurrying this way and that, carrying egg-cases out of the wreckage, establishing a defensive perimeter. Daniel stood opposite and looked at, but apparently did not see, the same things.

Within a few minutes Daniel had seen most of what he was going to see among the ants, within five minutes he was bored, within ten he had given up all pretenses and begun wandering round Hooke’s laboratory, looking at the remnants of everything that had passed beneath the microscope: shards of porous stone, bits of moldy shoe-leather, a small glass jar labelledwilkins urine, splinters of petrified wood, countless tiny envelopes of seeds, insects in jars, scraps of various fabrics, tiny pots labelledsnails teeth andvipers fangs. Shoved back into a corner, a heap of dusty, rusty sharp things: knife-blades, needles, razors. There was probably a cruel witticism to be made here: given a razor, Hooke would sooner put it under his microscope than shave with it.

As the wait went on, and on, and on, Daniel decided that he might as well be improving himself. So with care he reached into the sharp-things pile, drew out a needle, and carried it over to a table where sun was pouring in (Hooke had grabbed all of the south-facing rooms in the cottage, to own the light). There, mounted to a little stand, was a tube, about the dimensions of a piece of writing-paper rolled up, with a lens at the top for looking through, and a much smaller one-hardly bigger than a chick’s eye-at the bottom, aimed at a little stand that was strongly illuminated by the sunlight. Daniel put the needle on the stand and peered through the Microscope.

He expected to see a gleaming, mirrorlike shaft, but it was a gnawed stick instead. The needle’s sharp point turned out to be a rounded and pitted slag-heap.

“Mr. Waterhouse,” Hooke said, “when you are finished with whatever you are doing, I will consult my faithful Mercury.”

Daniel stood up and turned around. He thought for a moment that Hooke was asking him to fetch some quicksilver (Hooke drank it from time to time, as a remedy for headaches, vertigo, and other complaints). But Hooke’s giant eyes were focused on the Microscope instead.

“Of course!” Daniel said. Mercury, the Messenger of the Gods-bringer of information.

“What think you now of needles?” Hooke asked.

Daniel plucked the needle away and held it up before the window, viewing it in a new light. “Its appearance is almost physically disgusting,” he said.

“A razor looks worse. It is all kinds of shapes, except what it should be,” Hooke said. “That is why I never use the Microscope any more to look at things that were made by men-the rudeness and bungling of Art is painful to view. And yet things that one would expect to look disgusting become beautiful when magnified-you may look at my drawings while I satisfy the King’s curiosity.” Hooke gestured to a stack of papers, then carried a sample ant-egg over to the microscope as Daniel began to page through them.

“Sir. I did not know that you were an artist,” Daniel said.

“When my father died, I was apprenticed to a portrait-painter,” Hooke said.

“Your master taught you well-”

“The ass taught me nothing, ” Hooke said. “Anyone who is not a half-wit can learn all there is to know of painting, by standing in front of paintings and looking at them. What was the use, then, of being an apprentice?”

“This flea is a magnificent piece of-”

“It is not art but a higher form of bungling, ” Hooke demurred. “When I viewed that flea under the microscope, I could see, in its eye, a complete and perfect reflection of John Comstock’s gardens and manor-house-the blossoms on his flowers, the curtains billowing in his windows.”

“It’s magnificent to me,” Daniel said. He was sincere-not trying to be a Flattering Parasite or Crafty Knave.

But Hooke only became irritated. “I tell you again. True beauty is to be found in natural forms. The more we magnify, and the closer we examine, the works of Artifice, the grosser and stupider they seem. But if we magnify the natural world it only becomes more intricate and excellent.”

Wilkins had asked Daniel which he preferred: Wren’s glass apiary, or the bees’ honeycomb inside of it. Then he had warned Daniel that Hooke was coming into earshot. Now Daniel understood why: for Hooke there could only be one answer.

“I defer to you, sir.”

“Thank you, sir.”

“But without seeming to be a Cavilling Jesuit, I should like to know whether Wilkins’s urine is a product of Art or Nature.”

“You saw the jar.”

“Yes.”

“If you take the Rev.’s urine and pour off the fluid and examine what remains under the Microscope, you will see a hoard of jewels that would make the Great Mogul swoon. At lower magnification it seems nothing more than a heap of gravel, but with a better lens, and brighter light, it is revealed as a mountain of crystals-plates, rhomboids, rectangles, squares-white and yellow and red ones, gleaming like the diamonds in a courtier’s ring.”

“Is that true of everyone’s urine?”

“It is more true of his than of most people’s,” Hooke said. “Wilkins has the stone.”

“Oh, God!”

“It is not so bad now, but it grows within him, and will certainly kill him in a few years,” Hooke said.

“And the stone in his bladder is made of the same stuff as these crystals that you see in his urine?”

“I believe so.”

“Is there some way to-”

“To dissolve it? Oil of vitriol works-but I don’t suppose that our Reverend wants to have that introduced into his bladder. You are welcome to make investigations of your own. I have tried all of the obvious things.”

WORD ARRIVED THATFERMAThad died, leaving behind a theorem or two that still needed proving. King Philip of Spain died, too, and his son succeeded him; but the new King Carlos II was sickly, and not expected to live to the end of the year. Portugal was independent. Someone named Lubomirski was staging a rebellion in Poland.

John Wilkins was trying to make horse-drawn vehicles more efficient; to test them, he had rigged up a weight on a rope, above a well, so that when the weight fell down into the well, it would drag his chariots across the ground. Their progress could then be timed using one of Hooke’s watches. That duty fell to Charles Comstock, who spent many days standing out in the field making trials or fixing broken wheels. His father’s servants needed the well to draw water for livestock, and so Charles was frequently called out to move the contraption out of the way. Daniel enjoyed watching all of this, out the window, while he worked on Punishments:
