The doctor hadn't finished the medical session. "Replacement of body parts is easy, after all. The big trouble came when we went into the brain." "Brain?" Dan was startled. "How hard do you think your skull is?" Crander came closer. "Bend your head." Merrol obeyed and could feel the doctor's forefinger slice across his scalp in a mock operation. "This sector was crushed." Roughly half his brain, it appeared. "That's why so many memories were gone--not just from shock. In addition, other sectors were damaged and had to be replaced." Crander traced out five areas he could feel, but not see. "Samuel Kaufman, musician--Breed Mannly, cowboy actor--George Elkins, lepidopterist--Duke DeCaesares, wrestler--and Ben Eisenberg, mathematician, went into the places I tapped." Dan raised his head. Some things were clearer. The memories were authentic, but they weren't his--nor did the other wives belong to him. It was no wonder Erica had cringed at their names. "These donors were dead, but you can be thankful we had parts of their brains available." Crander delved into the file and came up with a sheet. "Here are some body part contributors." He read rapidly. "Dimwiddie, Barton, Colton, Morton, Flam and Carnera were responsible for arms and hands. Greenberg, Rochefault, Gonzalez, Tall-Cloud, Gowraddy and Tsin supplied feet and legs." * * * * * He was not a man, Merrol thought. Not now. If anything, he was a convention and one body was not a large enough hotel to hold it in comfort. "These were the major human donors, but there were others I didn't bother to read, for the kidneys and so on. And I think our four-footed friends deserve some mention." He looked up. "The skin on your face is from a pig embryo." That explained why it was hard to shave. "_Oink?_" he said. "I mean did it have to be a pig?" "You'd be surprised how hard it is to transplant human skin," commented Crander. "Besides, we wanted to give you a masculine look. The finest face there is, genuine pigskin." Merrol felt like a wallet. The doctor droned on through the list, but Merrol scarcely listened. Only once did he interrupt, to ask incredulously, "Did you say a _horse_?" "Is there anything wrong with a horse?" Merrol thought back. Come to consider it, there was nothing wrong--in fact, compliments were more in order. "The skill that went into matching the unrelated parts that are now you is a landmark in medical history, quite comparable to Harvey's discovery of the circulation of the blood," said Dr. Crander. "I wouldn't believe it if I hadn't participated in it myself. There have been limb and brain replacements before, but never on such a scale. One of these days, we'll get out a report that will astound the medical world." Without doubt, it would. Merrol tried to feel grateful, but gratitude refused to come. They had saved him--but was it worth it?
