The thinks of the Club were unanimously voted to the donors. 



The following gentlemen were balloted for and unanimously elected members 

 of the Club : Mr. William Bishop, Mr. Frederick C. Clark, Mr. G. 0. Drew, 

 Mr. John R. Furneaux, Dr. Arthur E. Sansom, Mr. Eobert P. Williams. 



Mr. Blankley introduced a new reflecting chimney for microscope lamps, in 

 which a coating of electro silver was deposited upon the outside of the glass, 

 and he had, at the suggestion of Mr. Swift, coated this with copper to preserve 

 it, and found it to answer admirably. He also exhibited and described a small 

 universal revolving stage, into which various pieces of apparatus could befitted. 



The President inquired who got the chimneys done, and who supplied them ? 



Mr. Blankley said Mr. Swift, of 43, University Street, supplied them. He 

 hoped to be able to bring them out at Is. each, but at present he found that 

 they cost rather more. 



Mr. T. C. White asked if they were liable to crack with the heat of the lamp? 



Mr. Blankley said that he had put the chimney which he exhibited to the test, 

 and found that it did not crack, and was in every respect most satisfactory. 



The Secretary read a letter which he had received from Mr. Furlonge, point- 

 ing out that the immersion paraboloid described in the July number of the 

 Journal was really the invention of Dr. Barker, of Dublin, although no mention 

 had been made of his name in connection with it. He (the Secretary) regretted 

 that neither Messrs. Ackland nor Suffolk were present, as he felt sure that they 

 would very readily explain the matter. 



Mr. Reeves said that the omission of Dr. Barker's name was evidently quite a 

 mistake, as the gentlemen in question were well aware of the facts, indeed he 

 had himself showed Mr. Suffolk the article describing the paraboloid in the 

 " Transactions of the Royal Dublin Society." 



Mr. T. Curties stated that as a friend of Mr. Furlonge he particularly noticed 

 at the time that Di\ Barker's name was mentioned, although it did not appear 

 in the Journal; had it not been mentioned he should certainly have called atten- 

 tion to it himself. 



The President was glad to have the matter so satisfactorily explained, and 

 said it could now be set right in the next number of the Journal. 



The proceedings then terminated with a conversazione, at which the following 

 objects were exhibited : — 



Scalariform Tissue of Pteris Aquilina ... by Mr. N. Burgess. 



Artemis Salina (alive) Mr. Burr and Mr. J . Williams. 



Palate of Cuttle Fish Mr. Mclntire. 



Antenna of Cockroach ... ... ... ... Mr. Richardson. 



Water Devil, Water Flea, &c Mr. Geo. Williams. 



Artemis Salina (mounted) Mr. R. P. Williams.
