One of the promoters of the [[Medical and Chirurgical Society of London]], of which he was the President in 1829, and which later became the [[Royal Society of Medicine]], Roget was also a founder of the [[Society for the Diffusion of Useful Knowledge]], writing a series of popular manuals for it.<ref name="Desmond"/> He wrote numerous papers on physiology and health, among them the fifth ''[[Bridgewater Treatise]]'', ''Animal and Vegetable Physiology considered with reference to Natural Theology'' (1834),  and articles for the ''[[Encyclopædia Britannica]]''. He was hostile to [[phrenology]], writing against it in a ''Britannica'' supplement in 1818, and devoting a two-volume work to it (1838).<ref>{{cite book |last1=Haskins |first1=Roswell Willson |title=History and Progress of Phrenology: (Read Before the Western Phrenological Society, at Buffalo,) |date=1839 |publisher=Steele & Peck |pages=[https://archive.org/details/2556039R.nlm.nih.gov/page/n200 181]–3 note |url=https://archive.org/details/2556039R.nlm.nih.gov |language=en}}</ref>
