80 DETONATING SYSTEM. 



gentlemen or to the other; so let them fight it out 

 themselves, and, in the mean time, leave me to go on 

 with my work. For I have as much dislike to su- 

 perfluous writing, as to interfering with the contests 

 of others. Enough of this now again to the point 

 about the powder. When, Mr. Joyce first brought it 

 forward, his agent in Birmingham had served him 

 with caps of brittle cannon-metal, instead of the best- 

 worked copper. The consequence was, that many 

 sportsmen, and I among the number, were severely 

 cut, and had nearly lost an eye, owing to the quality 

 of the cap, not the powder. This was of course a 

 glorious victory for all Mr. Joyce's oxygen-opponents, 

 arid the fault was unjustly laid on the composition. 

 I can only say, however, by subsequent experience, 

 that since Mr. Joyce has used nothing but good 

 copper, all the caps that I had of him have gone as 

 well as any in the kingdom, and his percussion 

 powder does not injure the guns any thing like so 

 much as the other. Let him, therefore, be very 

 careful, in future, to get supplied with GOOD 

 COPPER, of a good substance, and I may safely ven- 

 ture to recommend his " Anti-corrosive percussion 

 powder."
