Flotation in China

Just to note that I have revised my account of early flotation in China, in an attempt to be more accurate, but remain brief. It appears that in addition to efforts by Gary Crawford and others involved in the early Chinese-American collaborative projects (which have sadly, still produced little in the way of published reports !), that the Chinese archaeologist Xiong Haitang observed flotation  whilein Japan visiting Nagoya University, and published a Chinese account of the technique and its usefulness for environmental remains in general (includung fish bones and molluscs) in the journal Nongye Kaogu in 1989. This inspired its application at Lilou in 1992 described by Wu, Yaoli and Chen, Xingcan in the Chinese journal Wenwu Tiandin 1992.
