He took a beaker over to Fuzzy's platform and began squeezing off a little blob of pink material. Fuzzy seemed to sense what Dal wanted; obligingly he thrust out a little pseudopod which Dal pinched off into the beaker. With the addition of a small amount of saline solution, the tissue dissolved into thin, pink suspension.
In the laboratory they found two or three of the guinea pigs in the last stages of the infection, and injected them with a tiny bit of the pink solution. The effect was almost unbelievable. Within twenty minutes all of the injected animals began to perk up, their eyes brighter, nibbling at the food in their cages, while the ones that had not been injected got sicker and sicker.
"Well, there's our answer," Jack said eagerly. "If we can get some of this stuff injected into our friends down below, we may be able to protect the healthy ones from getting the plague, and cure the sick ones as well. If we still have enough time, that is."
They had landing permission from the Bruckian spokesman within minutes, and an hour later the Lancet made an orderly landing on a newly-repaved landing field near one of the central cities on the seventh planet of 31 Brucker.
Tiger and Jack had obviously not exaggerated the strange appearance of the towns and cities on this plague-ridden planet, and Dal was appalled at the ravages of the disease that they had come to fight. Only one out of ten of the Bruckians was still uninfected, and another three out of the ten were clearly in the late stages of the disease, walking about blankly and blindly, stumbling into things in their paths, falling to the ground and lying mute and helpless until death came to release them. Under the glaring red sun, weary parties of stretcher bearers went about the silent streets, moving their grim cargo out to the mass graves at the edge of the city.
The original spokesman who had come up to the Lancet was dead, but another had taken his place as negotiator with the doctors—an older, thinner Bruckian who looked as if he carried the total burden of his people on his shoulders. He greeted them eagerly at the landing field. "You have found a solution!" he cried. "You have found a way to turn the tide—but hurry! Every moment now is precious."
During the landing procedures, Dal had worked to prepare enough of the precious antibody suspension, with Fuzzy's co-operation, to handle a large number of inoculations. By the time the ship touched down he had a dozen flasks and several hundred syringes ready. Hundreds of the unafflicted people were crowding around the ship, staring in open wonder as Dal, Jack and Tiger came down the ladder and went into close conference with the spokesman.
It took some time to explain to the spokesman why they could not begin then and there with the mass inoculations against the plague. First, they needed test cases, in order to make certain that what they thought would work in theory actually produced the desired results. Controls were needed, to be certain that the antibody suspension alone was bringing about the changes seen and not something else. At last, orders went out from the spokesman. Two hundred uninfected Bruckians were admitted to a large roped-off area near the ship, and another two hundred in late stages of the disease were led stumbling into another closed area. Preliminary skin-tests of the antibody suspension showed no sign of untoward reaction. Dal began filling syringes while Tiger and Jack started inoculating the two groups.
"If it works with these cases, it will be simple to immunize the whole population," Tiger said. "From the amounts we used on the guinea pigs, it looks as if only tiny amounts are needed. We may even be able to train the Bruckians to give the injections themselves."
"And if it works we ought to have a brand new medical service contract ready for signature with Hospital Earth," Jack added eagerly. "It won't be long before we have those Stars, you wait and see! If we can only get this done fast enough."
