A vacancy in the Council was declared, by the resignation of Dr. 

 Mueller, and Mr. Eugene Von Guerard was nominated and elected. 



Mr. Cosmo Newberry, Analyst, Geological Survey, was nominated 

 as an Ordiuary Member. The ballot to be taken next meeting. 



Sir Eedmond Barry, on the part of Chief Justice Cockle, of 

 Queensland, handed in a paper " On DiflPerential Equations and Co- 

 resolvents." The paper was not of that character that could be read, 

 but by its publication, priority of discovery on a very important 

 branch of science would be obtained. Sir Redmond Barry stated 

 that Mr. Cockle ranked with Boole, Eawson, Cayley, and other 

 algebraic authorities ; had taken high mathematical honours at Cam- 

 bridge, and now employed his leisure moments in abstruse calcula- 

 tions of the character of the paper now presented. The theory pro- 

 pounded was a novel one, and strange to say, like the discovery by 

 Adams and La Verrier of the planet Neptune, Mr. Justice Cockle 

 had received a letter from ]\Ir. Harley, crossing one, sent home with 

 a similar discovery, the results of which were almost the same. Sir 

 Eedmond Barry trusted the Eoyal Society would see the necessity 

 of immediately publishing so important a paper, which must benefit 

 the Society as well as confer a benefit on science. 



The President then read a paper " On Eain-faU in Victoria." 



Mr. A. K. Smith made a few remarks as to the great utility a 

 knowledge of the rain-fall would have upon the construction of 

 various engineering works, instancing cases that had come under his 

 own immediate notice, and stating that a large amount of money was 

 wasted from a want of adherence to laws which had been so clearly 

 made manifest by the paper just read.
