A numerical investigation of three contagious distributions characteristic of epidemic data has been made using an electronic computer.

All three show a modified threshold effect such that the proportion of a community affected tends to 100% as its size increases though there is no abrupt change of form.

We would like to thank Mr M. J. R. Healy for assistance with one of the programmes, and Miss Molly Fretton for her help with the computing.
