Abstract
IN September of the coming year there will be a very favourable total eclipse of the sun, and several expeditions are preparing to proceed to stations on the narrow track of the moon's shadow. This eclipse is a member of an important family, from the point of view of solar physics, because one of its predecessors was the memorable eclipse of August 18, 1868. On this occasion the astronomical equipment was enriched for the first time by the use of the spectroscope for such work, and the important discovery of the gaseous nature of the solar prominences during that eclipse was the forerunner of very rapid advances in solar research. The track of the shadow was slightly to the north of the coming one, and passed over North-East Africa, India, Java, and North Australia. It was in India that the memorable observations were made.
