THESE two imposing volumes are the second fruits of the devotion of Mlle. Janssen to the memory of her father. On Janssen's death, in December 1907, she took upon herself the task of raising a memorial of his long and distinguished scientific career, and with the co-operation of M. Deherain, whose father and Janssen had been close friends from boyhood, a fund was accumulated for the erection of a monument on the terrace of the observatory at Meudon, which, during a period of more than thirty years, “he had paced with slow and regular step”. The undertaking was on the point of consummation when the War supervened, and, laying aside all other considerations, Mlle. Janssen devoted herself throughout the ensuing period of hostilities to the care of the wounded. At the, conclusion of the War this project was resumed, and on a beautiful afternoon in October 1920, a distinguished company paid homage to the memory of the dead astronomer.
