Even here, the overpossessiveness was evident, and Murt cringed from the pitiful, disconsolate expressions.

The cage before him, however, appeared normally animated. The monks were feeding and playing happily. Feldman was grinning. "Had to try a new derivative, Sylvester, but the sulfa series was the right approach."

Murt stared at the cage, redeyed. "Hadn't realized you succeeded in producing the symptoms in monkeys."

Phyllis said, "Why, I gave you that report yester—" She broke off with an understanding glance.

Peterson was exclaiming, "I never saw such a rapid-acting remedy! And so far, there's no evidence of toxic effect."

"It must absorb directly into the gland tissue," Feldman added. "Hardly had time to materially reduce the virus content significantly."

Murt murmured words of congratulations to them, turned on his heel and stalked out. Phyllis followed him to his office.

"Get me some of the stuff and notes on the dosages they administered," he ordered.

"Certainly," she said. "But why didn't you ask—Dr. Murt, you aren't going to try it on yourself?"

"Why not?" he barked hoarsely.

"It'll be weeks before we can determine if it's safe," she protested, horrified.

"We haven't got weeks. People are falling apart. This thing's contagious."

Even while Murt said it, he felt it was the wrong approach. He knew his own perspective was shot, but Phyllis would probably try to protect him against himself.

She did not. Instead, her face softened with sympathy and something else he refused to identify. She said, "I'll be right back."

The pressure in his head throbbed down his neck into his body. He wanted her so much, it was difficult to resist following her out into the hall. She returned in a few minutes with a 500-cc glass-stoppered reagent bottle half full of a milky fluid.

"Oral administration?" he asked.

She nodded. "Fifteen cc for the monkeys."

She secured a small beaker and a tapered graduate from the glassware cabinet and set them before him. He poured 50 cc into the graduated measure and transferred it to the beaker.
