More than once recently we have reproduced photograph 8 of lightning in our columns, but a photograph by Dr. H. Kayser, which we now reproduce from the Mittheilungen, possesses characteristics which have never before been seen in a photograph of the electric discharge. Not only are equatorial stratifications visible in the mam flash, as is the case of a discharge in an exhausted receiver but there are four distinct lines of light running side by I other through the whole course, as shown in the photo side, and these keep approximately parallel with each | graph.
