Thence he moved to Cork, where he lectured on materia medica and medical botany in a private school of anatomy, medicine, and surgery in Warren's Place.
He published in 1844 ‘Medicines, their Uses and Mode of Administration,’ which gives an account of all the drugs mentioned in the London, Scottish, and Irish pharmacopœias, and of some others.
Their sources, medicinal actions, doses, and most useful compounds are clearly stated; and the compilation, though containing no original matter, was useful to medical practitioners, and went through many editions.
He enjoyed the friendship of Robert James Graves, the famous lecturer on medicine, and in 1848 edited the second edition of his ‘Clinical Lectures on the Practice of Medicine.’ In the same year he published ‘The Diagnosis and Treatment of Eruptive Diseases of the Scalp,’ which was printed at the Dublin University Press.
He describes as inflammatory diseases herpes, eczema, impetigo, and pityriasis, and as non-inflammatory porrigo, and gives a lucid statement of their characteristics in tabular form; but he was ignorant of the parasitic nature of herpes capitis, as he calls ringworm, and seems not to have noticed the frequent relation between eczema of the occiput and animal parasites.
