This con- dition may remain for days, a week, or even more ; it may be regarded as the ix-ritxl of incubation of the disease ; loss of appetite, with more or less of gastric derangement, are often ol>servuble, but 1 have known a patient to cat his meals as usual during the whole of the jrtkhI of malaise.
