Since our last publication it has been ascertained, that when placed in a negative vessel, worts will remain sound for a much longer time than when put into a positive vessel.

But when the gyle-tuns are in a negative state, the fermentations will go on very languidly, and occasionally become quite stationary; while on the contrary, under a different state of electro-chemical action, they will go on violently and uncontrollably, but without the due attenuation.



An airy unconfined situation should, if possible, always be selected for the site of a brew-house, so
