Then I got tuberculosis and that was due to overwork and weakened condition, and that was a long business. It took nearly two years to clear that up and every day I took what I call two buckets of sand and cement, which was a liquid called... a liquid drink called passaia [sic], which was the only - in those days - known cure for TB, which hadn't really had a cure until the 1950s... there was no cure before that. And so I took this every day and it was revolting stuff but I knew enough people in the medical profession to seek advice and I met my friend Joe Briggs, who was a sort of peripatetic physician and he knew all the hospitals and all the people and so forth. And we went to Guy's and we went through the medicine depositories and we picked out various packets of this ghastly stuff and we mixed it with different things and in the end we found that if we mixed it with a certain quantity of orange juice and blackcurrant and so forth, it became easier to drink, so then I was able to take this stuff. The way to take it is you just open the throat and pour it down. It mustn't touch the sides because then you might feel the effects of it. And after two years, it was said I was cured and I went back to see my specialist and he was very pleased. He said, 'A complete cure, marvelous, doesn't always happen like that. How much of the passaia [sic] did you take?' 'Well', I said, 'I took it all'. Every drop of it I took, for two years. 'Really', he said, 'that's very interesting'. He said, 'Most people only take about 50% of it, so we always double the dose'. But it worked anyhow.
