Note 822 — Chapter V · (continued 3)

‘It seems impossible to peruse the passages I have quoted from Dr. Cullen's manuscript lectures and papers, and from his Essay on Evaporation, without perceiving that his investigations with regard to the heat and cold occasioned by the combination, liquefaction, and evaporation of bodies, must not only have assisted to direct the attention of his pupil Dr. Black to similar inquiries, but must also have furnished him with several of the data from which his simple and comprehensive theory of Latent Heat was afterwards so philosophically deduced.’ Thomson's Life of Cullen, vol. i. p. 56.
