Report on the magnetic observations made at Vlissingen (Flushing), Holland, during the total solar eclipse of May 17, 18, 1901

Abstract

These observations were taken on a plot of grass land just inside the sea dyke, a little to the southwest of the house of the observer, for the Royal Meteorological Institute. The spot, being too near to the passage of the steamers between the river and the sea, was not to be considered as a perfectly safe one for absolute measurements. However, as it was in every other respect exceptionally convenient, and as it was thought that, if good note were taken of every suspicious circumstance, disturbances due to this cause could be readily separated from those of a cosmic origin, the locality was retained.A temporary shed was erected for me by the kindness of Mr. P. Hoogenbooin, engineer of the “waterstaat.” I avail myself of this opportunity to express my gratitude to him, as also to the gentlemen who volunteered to assist me, Mr. Engelenberg, C. E., my former very much valued assistant in Brazil; Mr. C. Schoute, the able assistant in the physical laboratory of Groningen University, who assisted me, with the kind permission of Professor Haga, and Messrs. H. I. I. Kress and H. Az. de Ruyter, the former a computer of the Meteorological Institute at de Bilt, and the latter, the observer at Vlissingen.
