Abstract
EDINBURGH Royal Society, July 20.—Mr. David Milne-Home, LL.D., Vice-President, in the chair.—Dr. Harvey Gibson read the second part of his paper on Patella.—Prof. Tait read a paper by the Rev. T. P. Kirkmanon the unifilar knots with ten crossings; and also a paper of his own on the census of ten-fold knotti-ness. There are 364 different forms of ten-fold knottiness, when the crossings are alternately over and under, included in 124 types, 50 of which are unique, while 74 have multiple forms.—Prof. Tait also communicated a paper by Messrs. Crocket and Creelman on the thermal effects produced in solids and in liquids by sudden large changes of pressure, and a paper by Mr. W. Peddie on a method of determining the resistance of electrolytes without endeavouring to prevent polarisation.—Prof. MacFadyean and Dr. G. S. Woodhead submitted an account of the construction of the auricles of the pig's heart. Beating of the heart and the superior vena cava may continue under proper stimulation for a few hours after death.—Mr. A, P. Laurie communicated a note of the heat of solution of zinc iodide. The heat of solution was determined by observations of the electromotive force of a voltaic cell invented by himself for the purpose.—Dr. J. McFarlane read a second paper on pitchered insectivorous plants.—Mr. H. R. Mill, of the Scottish Marine Station, read a paper on the salinity of the Tay estuary and of St. Andrew's Bay.—The meeting, which was the last for the session, was concluded by an address from the chairman.
