 There was briefly (1830–31) a medical school in Brewer Street, set up by William Birmingham Costello, Epps and Michael Ryan.Epps and Ryan then joined George Darby Dermott in giving lectures at the Western Dispensary in Gerrard Street; James Fernandez Clarke, in his memoirs, described Epps lecturing there as well-read and sympathetic but not deeply versed in practical chemistry, or botany.Epps lectured publicly and extensively for the rest of his life, particularly on phrenology and homoeopathy, in London and elsewhere.
