THE BRISTOL PERIOD 71 



might reasonably be expected to curtail seriously the 

 time available for study and the continuance of experi- 

 mental research. This, however, does not seem to 

 have interrupted the output of results from Ramsay's 

 laboratory, for in the years 1881 and 1882 five papers 

 were communicated to the Chemical Society, one being 

 the joint production of the Professor and the Demon- 

 strator David Orme Masson, who later became Professor 

 of Chemistry in the University of Melbourne. 



Ramsay was fortunate in having a succession of able 

 assistants in the teaching work. Masson left the College 

 in 1881 and was succeeded by Dr. Adrian Blaikie (who 

 died a few years after leaving Bristol in 1882), and for 

 a very short time Mr. W. L. Goodwin occupied the post. 

 He was succeeded by Dr. Sydney Young in 1882, who 

 remained in association with Ramsay till the departure 

 of the latter five years later for University College, 

 London. Young was then appointed to the vacant 

 chair. When Dr. Young went to Bristol in 1882 he 

 found Ramsay engaged in two investigations : the first 

 on the specific volumes of liquids at their boiling points, 

 and the second the determination of the vapour pres- 

 sures and critical constants of benzene and ether. 



The supposed phenomenon of " hot ice " had also 

 just previously occupied a good deal of attention, and 

 in the investigation of all these subjects Ramsay invited 

 Young to join him. The result was a series of papers 

 on the thermal properties of solids and liquids and on 

 the relation of evaporation to dissociation, which extended
