Abstract
THE Journal of the Royal Microscopical Society for April contains the President's Annual Address, the last instalment of his valuable series of addresses on the mathematics of the construction of microscopic lenses. In this address, Mr. E. M. Nelson devotes himself to the aplanatic immersion front and the Huyghenian eye-piece, and deals with the errors of this lens, viz. chromatism, curvature of image, distortion, and astigmatism. A new feature in the present number is the extension of the bibliography to microscopical technique and bacteriology.
