Abstract
THE seventh volume of Annales de l'Observatoire Météorologique Physique et Glaciaire du Mont Blanc (altitude 4350 metres) has now been published, under the direction of M. J. Vallot, founder arid director of the observatory, following the sixth volume which was published in 1905 (tome 7, Paris, G. Steinheil, editeur, 1917). It records the death of Janssen in 1908 and the transformation of the provisional society of his observatory at the summit (4808 metres) into a société définitive which placed that observatory also under the direction of M. Vallot. Both were utilised in 1908, but that on the summit became not merely uninhabitable, but dangerous, and it was therefore demolished in 1909. Since that date work has been carried on only at M. Valot's observatory, which he had placed at the disposal of the society. The volume referred to deals only with the work accomplished before the union of the observatories. The researches made at the cost of the society have been published en résumé in the Comptes rendus; those which- cannot find a place there, as well as reports in extenso, will appear in later volumes of the Annales.
