I lay still on the bed, watching him.
‘So the next problem would be to remove your brain, intact and undamaged, from your dead body. The body is useless. In fact it has already started to decay. The skull and the face are also useless. They are both encumbrances and I don’t want them around. All I want is the brain, the clean beautiful brain, alive and perfect. So when I get you on the table I will take a saw, a small oscillating saw, and with this I shall proceed to remove the whole vault of your skull. You’d still be unconscious at that point so I wouldn’t have to bother with anaesthetic.’
‘Like hell you wouldn’t,’ I said.
‘You’d be out cold, I promise you that, William. Don’t forget you died just a few minutes before.’
‘Nobody’s sawing off the top of my skull without an anaesthetic,’ I said.
Landy shrugged his shoulders. ‘It makes no difference to me,’ he said. ‘I’ll be glad to give you a little procaine if you want it. If it will make you any happier I’ll infiltrate the whole scalp with procaine, the whole head, from the neck up.’
“Thanks very much,” I said.
‘You know,’ he went on, ‘it’s extraordinary what sometimes happens. Only last week a man was brought in unconscious, and I opened his head without any anaesthetic at all and removed a small blood clot. I was still working inside the skull when he woke up and began talking.
‘ “Where am I?” he asked.
‘ “You’re in hospital.”
‘ “Well,” he said. “Fancy that.”
‘ “Tell me,” I asked him, “is this bothering you, what I’m doing?”
‘ “No,” he answered. “Not at all. What are you doing?”
‘ “I’m just removing a blood clot from your brain.”
‘ “You are?”
‘ “Just lie still. Don’t move. I’m nearly finished.”
‘ “So that’s the bastard who’s been giving me all those headaches,” the man said.’
Landy paused and smiled, remembering the occasion. ‘That’s word for word what the man said,’ he went on, ‘although the next day he couldn’t even recollect the incident. It’s a funny thing, the brain.’
‘I’ll have the procaine,’ I said.
‘As you wish, William. And now, as I say, I’d take a small oscillating saw and carefully remove your complete calvarium – the whole vault of the skull. This would expose the top half of the brain, or rather the outer covering in which it is wrapped. You may or may not know that there are three separate coverings around the brain itself – the outer one called the dura mater or dura, the middle one called the arachnoid, and the inner one called the pia mater or pia. Most laymen seem to have the idea that the brain is a naked thing floating around in fluid in your head. But it isn’t. It’s wrapped up neatly in these three strong coverings, and the cerebrospinal fluid actually flows within the little gap between the two inner coverings, known as the subarachnoid space. As I told you before, this fluid is manufactured by the brain and it drains off into the venous system by osmosis.
‘I myself would leave all three coverings – don’t they have lovely names, the dura, the arachnoid and the pia? — I’d leave them all intact. There are many reasons for this, not least among them being the fact that within the dura run the venous channels that drain the blood from the brain into the jugular.
‘Now,’ he went on, ‘we’ve got the upper half of your skull off so that the top of the brain, wrapped in its outer covering, is exposed. The next step is the really tricky one: to release the whole package so that it can be lifted cleanly away, leaving the stubs of the four supply arteries and the two veins hanging underneath to be re-connected to the machine. This is an immensely lengthy and complicated business involving the delicate chipping away of much bone, the severing of many nerves, and the cutting and tying of numerous blood vessels. The only way I could do it with any hope of success would be by taking a rongeur and slowly biting off the rest of your skull, peeling it off downward like an orange until the sides and underneath of the brain covering are fully exposed. The problems involved are highly technical and I won’t go into them, but I feel fairly sure that the work can be done. It’s simply a question of surgical skill and patience. And don’t forget that I’d have plenty of time, as much as I wanted, because the artificial heart would be continually pumping away alongside the operating-table, keeping the brain alive.
‘Now, let’s assume that I’ve succeeded in peeling off your skull and removing everything else that surrounds the sides of the brain. That leaves it connected to the body only at the base, mainly by the spinal column and by the two large veins and at the four arteries that are supplying it with blood. So what next?
