Squire, PmocZ o/Jw/., p. 34, Looking at the variation of range here shown, it is somevehat difficult to make x^ractical application of the information. An average will not do, because about as many cases would exceed as fall within a limit so fixed. The only method available is to carefully consider the weight of the different opinions, and, adding a considerable margin of safety, fix a definite number of days as that which should be held to be the incubative period. Because a definite period must be decided on, it would be nearly useless advice to a school proprietor about to disperse his pupils on account of an outbreak of some infectious fever, to say to^ him, You must delay them for from seven to twenty-one days. In fact no physician would do so; he would fix some limit for himself, and the evil at present is that another, though not really differing much in opinion, may at haphazard name a shorter or a longer period, much to the mystification of the public.
