ABSTRACT
C The first results were reported from 1959 onwards, Anon. (170, 124, 126), and in 1964 we were able to see the work at first hand in the Chungshan Hospital at Shanghai and obtain the figures in Table 2 I. Our thanks are due to Dr Li Chieh-Ying and Dr Hsiung 1u-Chheng for their kindness on that occasion.
