Abstract
FRANCE is again called upon to mourn the loss of a veteran astronomer whose services have rendered him conspicuous among the many eminent men of science his' country has given to the world. Jules Janssen, born in 1824, was first a painter, but for more than fifty years contributed to the scientific literature of his cpuntry and enriched many departments of physics by his untiring energy, his accurate observations, and his fertility of resource. He was a great traveller; his first scientific expedition was in 1857 to Peru, to study the magnetic equator. Ten years after he was studying the eruption of Santorin, with Fouque. It is not possible to do justice to his work within a small compass, but fortunately its salient features will long remain fresh in our memories.
