all this can take place each summer in the same way in Grinnell Land, at 82° N., especially as the access to food must be more limited than it is with us. The development of the humble-bee colony must surely be quite different there. If it is not surely proved that the humble-bees occur at so high latitudes, one would not, with a knowledge of their mode of life, be inclined to believe that they could live under such conditions. They seem, however, to have one advantage over their relatives in the south. In the Arctic regions none of those parasites are found which in other regions lessen their numbers, such as the _conopidæ_ among the flies, the mutillas among the hymenoptera, and others."--_Psyche._ [Footnote 2: Nordenskiöld, A.E., Studien und forschungen veranlasst durch meine reisen im hohen norden.

[Footnote: Volunteer report presented to Nebraska State Medical Society, May, 1885, at Grand Island, Neb.] By L.A. MERRIAM, M.D., Omaha, Neb., Professor of the Principles and Practice of Medicine in the University of Nebraska College of Medicine, Lincoln, Neb. The records of the Nebraska State Medical Society show that the only report of progress on nervous and mental diseases ever made in the history of the society (sixteen years) was made by the writer last year; and expecting that those appointed to make a report this year would, judging by the history of the past, fail to prepare such a report, I have seen fit to prepare a brief volunteer report of such items of progress as have come to my notice during the last twelve months. I have not been able to learn that any original work has been done in our State during the past year, nor that those having charge of the insane hospital have utilized the material at their command to add to the sum of our knowledge of mental diseases.
