sphere by passing it througha refrigerating-chamber, the daily records of operations, setforth in Table VIII. (page 768), will give a very clear idea. During thirteen days, the average moisture in the atmos-phere was 5.66 grains per cu. ft.; and in the dry air 1.75 grains;69 lb. of water were removed from the blast per ton of iron pro-duced, which represents an average of 23,192 lb. (2,784 U. S.standard gallons) for the 24 hours. This weight was calcu-lated from the volume of air blown into the furnace, as shownby piston-displacement. For four days during the above periodthe water, caught in the tank underneath the refrigerating-chamber, amounted to an average of 21,561 lb. (equivalentto 2,588 gal.) for the 24 hours, which is as close an agreementas could be expected, considering that the figures do not rep-resent the same number of days, and that it is difficult todetermine accurately the volume and humidity of the air sup- APPLICATION OF DRT-AIB BLA81 fO MANUFACTURE OF (RON. 7*>7
