I was very fortunate at the time, Lord Rothschild was a good friend of mine and I used to go and drink martinis with him every weekend. And he was for many years a scientist in the zoology department, and when he stopped doing science he had a technician - Nichol Thomson - who worked for him for many years, and whom he was anxious to find a job for. And he talked to me about it, and I said, this is ideal, I'd love to - Nichol was an electron microscope technician - and I said, I will get Nichol a job. And of course I wanted him, so he came and joined me. I have to say we had a lot of problems at the time because Nichol hadn't had a... a higher education in his life, having been born in a small... a small town in Scotland and not... had not completed much of... of higher education, let alone school education. And of course this was still... this was just in the days where people began to worry about qualifications and so on, which I think's completely nonsense. And of course we had to have... have a lot of arguments with administrators. We finally got Nichol a... a decent appointment, and he came in and began to tackle the problem... of these little beasts.
