The Journal of the Asiatic Society of Bengal, 1847-pt. 1-193 records a fall of an olive-gray powder at Shanghai on March 16, 1846. Under the microscope, it was “seen to be an aggregation of hairs of two kinds, black ones and rather thick white ones.” When burned, they smelled of ammonia and burnt hair or feathers.
