Photographs taken by Joseph Needham of scientific institutions in Chengtu (Chengdu) 成都市 and Chiating (Jiading) 嘉定 (now Leshan 樂山), Szechuan (Sichuan) province 四川省. Chronologically the roll comes between SZE1 and SZE8. A few of the pictures are of mediocre quality due to slight damage to the negatives and blurring.
