Abstract
The authors report results from recording the short time-scale dynamic phenomena of weeping with a high-speed video system equipped with a l ong-distance microscope and stopped-motion photographs with a 35-mm ca mera equipped with a 150-mm macro lens stacked on a 200-mm telephoto l ens. With few exceptions, the weeps all share a common structure: a bu lbous crown on top of a comb of separate columns or ''trunks'' that jo in, two-by-two, in their upper reaches.
