    its different forms, lias been arrived at in two ways; by taking the average age of all the cases, and by ascertaining the numbers in each period of life. Table YII gives tlie average age of each sex, of all the cases of each form of fever, admitted into the London Fever Hospital during ten years. Table YII. Males. Females. Males and Females.

Table YIII (see next page) shows the number of each fever in each quinquennial period of life for either sex. (See also Diagram IY.) In continued fever, taken as a whole, and also in each of its individual forms, the three most common lustra of life appear, from Table YIII, to be 15 to 20 years, 20 to 25, and 10 to 15, in the order here given. The relative excess of cases, however, belonging to these lustra, varies greatly, being greatest in typhoid, and least in typhus. Thus, more than one half (52 per cent.) of the cases of typhoid are included in the two most common lustra, or between 15 and 25 years of age; but only 38i per cent, of the cases of relapsing fever, and less than one third (30 per cent.) of the cases of typhus. Again, one fifth of the cases of typhoid,
