10 WILLIAM GOSSAGE 



I accelerate this absorption of oxygen by 

 causing the fluid mixture to be projected into 

 the air in finely divided particles by communi- 

 cating rapid rotary motion to the shafts and 

 paddles before mentioned. The absorption 

 of oxygen converts the hydrated protoxide of 

 manganese into hydrated peroxide." 



Complete as these reactions are, and simple 

 as the process seems to be, as a fact, it never 

 was adopted, and not until Mr. Walter 

 Weldon gave his attention to the recovery of 

 manganese liquors, more than thirty years 

 afterwards, did the alkali manufacturer save 

 his manganese. Mr. Weldon recognised 

 fully that the chemistry of his process was 

 demonstrated by Mr. Gossage ; and Mr. 

 Gossage recognised the ability and the 

 perseverance with which Mr. Weldon, aided 

 by vastly improved mechanical appliances, 

 brought his invention to a tangible success. 

 To the engineer rather than to the chemist is 

 the triumph of Weldon to be attributed. 



The second portion of this memorable 

 patent of August, 1837, forecasts the successes 

 of Mond and Chance in their successful 

 sulphur recovery processes. Gossage saw 

 that the sulphur used in the Leblanc pro- 

 cesses was absolutely wasted, and nine-tenths
