^{page 501 note *} This form is sometimes seen when a case of measles develops in a ward in which a number of susceptible children are confined. Although the sufferer be moved at once, yet the infection is present so early in the disease that usually several others succumb. In one actual case, when there were fourteen susceptible children in a ward, the epidemic developed in the following way. First one case; at the end of incubation period three cases; then a fortnight later seven; leaving only three to develop the disease, and these all succumbed in the next fortnight, so that the epidemic came to an end from the cause discussed and took the form of diagram XV. This, however, is under artificial conditions, and bears no resemblance to a natural outburst.
