A small quan- 

 tity of light 

 breeze only 

 left after 

 working off 

 the gas. 



This is not a guaran- 

 teed samjile, it was 

 obtained from the 

 s.s. 'Luna,' and may 

 possibly have other 

 coal mixed. 



The quantity regis- 

 tered is doubtful. 



Retorts were at a much 

 greater heat than in 

 the preceding and 

 following examples. 



Retort at only a dull 

 red, about 1,000°. 



Illuminating poweras- 

 certaiued after gas 

 had been stored 

 some time, perhaps 

 two or three days. 



This gives illuminating 

 power after storage, 

 and as was supplied 

 to cousimiers.
