Some remarks on the early history of vibrating Leidenfrost drops

Leidenfrost drops often exhibit symmetric shape-oscillations when placed onto curved substrates. We give some brief remarks on vibrations found in liquids floating over highly heated surfaces for the overlooked period from the late 1700s up to the work of Holter and Glasscock in 1952 [J. Acoust. Soc. Am. 26, 253 (1952)]; the latter pair were incorrectly credited as the first to observe such behavior in Leidenfrost drops.
