parcel was discovered, and he had brought them to the meet- 

 ing that evening; they were, as might be expected, very- 

 excellent slides, and they would be a very valuable addition to 

 their cabinet. 



Mr. J. E. Ingpen said they would be very glad to have this 

 memento of Dr. Gray, whom he was very sorry to lose as a 

 member of the Club. The older members would remember 

 very well the valuable services he used to render during years 

 when he was a member of their committee, and felt sure that 

 this donation would be greatly appreciated by all who knew 

 him. 



The President said that when Dr. Gray left London he lost 

 a personal friend. He certainly never had met with a more 

 earnest and thorough worker or one who devoted himself more 

 disinterestedly to the advancement of microscopical science. 



A hearty vote of thanks to Dr. Gray was unanimously 

 passed. 



Mr. Karop said they had also received a donation of slides of 

 Foraminifera from the Andaman Islands and other places from 

 Mr. Jenkins. 



Mr. Karop exhibited and described a microscope lamp made 

 by Mr. Swift on the IsTelson-Dallinger pattern, but having an 

 arrangement for putting the blue glass in front of the doublet, 

 instead of in the side of the chimney, where it was very apt to 

 get cracked by the heat. Another improvement consisted of a 

 metal ring, which was put round the top of the chimney and 

 connected to the upright stem, which acted as a condactor and 

 conveyed the heat away from the chimney to the stand and 

 greatly modified the amount, which was so inconveniently 

 radiated from the hot chimney under ordinary circumstances. 

 The price, inclusive of the condenser and blue glass, was about 

 50s. 



The President said it was a good idea to separate the glass 

 from the chimney. He much preferred, however, the blue 

 glass to be mounted upon a separate stand, as being more 

 easily removed when not wanted. He fancied that there 

 might also be some inconvenience in conducting the heat to 

 the body of the lamp, where it might so overheat the oil as to 

 cause it to boil. 



Mr. Karop said it had been kept alight continuously for six
