a Scottish physician. He was the author of several works on physical science or its applications, the most important being his Elements of Physics (1827), which went through six editions in his lifetime. From his earliest youth, Arnott had an intense love of natural philosophy, and to this added an inventiveness which served him in good stead in his profession and yielded the Arnott waterbed in 1832, which later was developed into a water-filled chair intended to prevent seasickness.
