 placj in tlie growtli of tlie koji fulfils. 'I'liis )in«ossof les pi ration, or oxidation, 

 as a clieniist 7iiiglit call it, is acconi]ianie(l l)y a reniarkalilcj develoinnent of heat 

 sufficient to keep tljc temperature of tlie ki'ji arid of the cliamber v(>ry higli. 

 Tlie following tem]ieratiire observations will show this — the first series was made 

 in sjiring when the, amount of ki'iji liuiiig made was very small, and the outside 

 temperature not very nmeh below that of the chamber. In the second series of 

 observations, made in Decendier, the difi'erences are much greater, the (em[)eratm'0 

 of the outsi(h' air being very low. and that of the koji Tnnch higher. Puring the 

 month in which these observations were made the amount of material produced 

 is %^ery large, and the chambers are kept fully worked : it is owing to this 

 circumstance that the dilferences ot' temperature between the koji and thatof tlic 

 chamber are so much more marke(l than in fthiv.
