the College of Physicians, with its older, smaller, and jealously guarded fellowship, a more congenial sphere.
The College of Pharmacy was founded in 1821, and, the year following, Dr. Wood accepted an invitation to the chair of Chemistry, without, however, severing his connection with the Association. This position he held with increasing reputation until 1831, when it was exchanged for the chair of Materia Medica in the same institution.
