 During Perkin's time there, new and more extensive laboratories were built (the Dyson Perrins Laboratory), and for the first time in England a period of research became a necessary part of the academic course in chemistry for an honours degree.But the constant rivalry with the physical chemistry department, for example Frederick Soddy, lead to the situation that most of the graduates chose physical or inorganic chemistry as their subject, and Perkin got most of his postdoctoral employees from other universities.Perkin's work was published in a series of papers in "Transactions of the Chemical Society".
