MR. HENRY JAMES WADDINGTON, who died at Bournemouth on June 28 at ninety-one years of age, was well known to microscopic workers both at home and abroad. Many of his preparations, especially those of prawns and crabs, as well as various protozoa, are exhibited in the Natural History Museum, South Kensington. His wonderful manipulative skill at mounting the most delicate protozoa and insects in their natural condition was the admiration of all who came in contact with him. His knowledge of chemistry was an enormous help to him, and his successful preparation of realgar as a mounting medium of high refractive value, as well as his mounts of various diatoms in realgar, are known to many. Mr. Waddington was one of the founders of the Natural Science Society of Bournemouth, and was later presented with the gold medal of the society and elected honorary vice-president.
