This letter admires the letterhead of the East Asian History of Science Library at 8 Shaftesbury Road ‘I was especially delighted in seeing the brightly red seal in Chinese: For official correspondence only for the Science and Civilisation in China Project. You are more Chinese than the Chinese themselves in a way.’ It also mentions Lo Chung-shu [Luo Zhongshu 羅 忠叔] and his nephew Chen Woo-zhen [Chen Wuzheng 陳務正] who was a chemical engineer in Nanking Chemical Research Institute [Nan Hua yan jiu yuan 南化研究院].
