The data given by Maguire, Pearson & Wynn (1952) on the time intervals between successive coal-mining disasters involving 10 or more men killed have been found to contain a number of errors. The original numbers have been quoted and used by a number of authors. The present note corrects the errors in the original paper and extends the data set to cover 191 disasters between 1851 and 1962.
