            Abstract : 
Theoretical and practical aspects of the application of electrical guards to resistance thermometers are discussed, with a view toward suppressing errors caused by imperfect electrical insulation at high temperatures. Some simple techniques for modifying existing resistance thermometer bridges are described.
