Abstract
ARACHNOLOGISTS must unite in a vote of thanks to Drs. Hansen and Sörensen for their splendid achievement in producing their treatise on Arachnida. The volume, announced many years ago as in preparation, is based upon a wealth of material borrowed from every available source such as no other taxonomists have been able to examine. It is a monument of careful research, and in every way worthy of the high reputation of its authors. Though written in a foreign tongue, the letterpress contains no passage of doubtful meaning; and Hansen's inimitable drawings have received full justice from the lithographic skill of Wilson at Cambridge. The Royal Society was well advised in contributing to the cost of publication.
