Mr. J. D. Hardy exhibited and described a gas lamp for microscopic use, 

 which was an adaptation of the Albo- Carbon burner to a table lamp-stand. 

 In reply to a question from Dr. Matthews, Mr. Ingpen explained that the 

 substance known as Albo-Carbon was common crude Napthaline, which was 

 deposited by condensation in the gas mains in cold weather, causing stop- 

 pages of pipes, &c. ; the gas burner known by this name was a contrivance 

 for restoring this element to the gas, and to some extent super-carburetting 

 it at the burner. 



Mr. BadGock said the saving of gas would more than compensate for the 

 extra cost of burner and carbon, as a better light could be got in this way 

 with a No. 1 burner than with ordinary gas and a No. 7. With proper care 

 there was no smell with it to any extent. 



Mr. E. M. Nelson exhibited and described an arrangement for facilitating 

 the fixing of objectives to nosepiece of microscope. 



Some discussion as to whether the idea was new then took place, during 

 Journ. Q. M. C, Series II., No. 4. o.
