Excerpt from The Journal of the Institution of Electrical Engineers, Originally the Society of Telegraph Engineers, 1920: Supplement to Vol. 57, 1919 After a great deal of consideration Gamgee decided to adopt thermo-electric couples in preference to resist ance thermometers, and I think it will be generally agreed that for work of high precision his decision was a correct one. The construction of his apparatus is fully explained in his paper, but it may be of interest to give a short description. The thermometers used were of two kinds, one for taking the temperature of the surface of the skin and the second for the temperature of the cavities of the body. The materials of which the thermo-electric couples were made were copper-constantan, materials which long experience has shown form' one of the most satisfactory thermo-elements.
