A memoir of the late Mr. James Glaisher, F.R.S., appeared in the April number of the Aeronautical Journal, so it seems hardly necessary for any further reference to be made to him. But since that time the instruments and apparatus used by him in his famous balloon ascents have, by the courtesy of his son, Dr. J. W. L. Glaisher, F.R.S., come into the possession of the Royal Meteorological Society.

Your Secretary, Mr. E. S. Bruce, was very desirous that these instruments should be exhibited at a meeting of the Aeronautical Society, and thought that it would be interesting to most of the members if a brief account of Mr. Glaisher's balloon ascents was given at the same time. I could not refuse this request, as Mr. Glaisher was for some time my chief at the Royal Observatory, Greenwich, although I think a more interesting account might have been prepared by someone else.
