Abstract
DUBLIN. Royal Dublin Society, June 22.—Prof. D. J. Cunningham, F.R.S., in the chair.—Dr. E. A. Letts and Mr. R. F. Blake communicated a paper on the carbonic anhydride of the atmosphere. The first part was read dealing with (1) a brief historical account of the subject, with a discussion of the methods which have been employed in the determinations; (2) a description of the authors’ modification of Pettenkofer's process, whereby results of great accuracy were obtained with mixtures of known volumes of purified air and carbonic anhydride; (3) an account of the authors’ experiments (qualitative and quantitative) on the action of weak baryta water on glass; and (4) on the disturbing effect produced by soluble silicates on the delicacy of the phenol colour reaction with alkalis.—A paper was next read by Mr. E. St. John Lyburn, of Pretoria, consisting of notes on the minerals and mining in the Transvaal and Swaziland.—This was followed by a paper by Mr. A. Vaughan Jennings and Mr. H. Hanna on Corallorhiza innata, R.Br., and its mycorhiza.
