1895 C. V. Boys ; W. F. R. Weldon; J. B. Pettigrew 467 



Charles Vernon Boys, Associate of the Royal School of 

 Mines, was for some years Demonstrator and Assistant 

 Professor of Physics at the Normal School of Science, 

 South Kensington. He is one of the most inventive members 

 of the Club and one of the most successful experimenters of 

 the day. He is the author of some valuable contributions 

 to science on soap-bubbles, quartz-fibres, radio-micrometers, 

 the measurement of the Newtonian Constant of Gravitation 

 and other subjects. He repeated the torsion-balance 

 measurement of Michell and Cavendish with a delicacy and 

 accuracy never before attained. 



The guests this year included William Ramsay, who dined 

 on the invitation of William Crookes on 3ist January, six 

 months before his election into the Club. It is recorded in 

 the dinner-register that after the three usual toasts had 

 been given J. W. Hulke, the Junior Treasurer, took advan- 

 tage of the presence of one of the discoverers of Argon to 

 propose as a further toast "The infant Argon, and may 

 his future surpass the most sanguine expectations of his 

 parents." The toast was drunk with enthusiasm, and 

 Professor Ramsay said a few words in reply. 



Another distinguished visitor came to the dinner on 

 May 9th as the guest of Francis Galton Professor Walter 

 Frank Raphael Weldon. This accomplished naturalist had 

 passed with great distinction in the Natural Sciences Tripos 

 at Cambridge and after some busy years, devoted chiefly 

 to morphological work, had turned to the investigation of 

 the problems of the variation and correlation of living 

 things. He became F.R.S. in 1890. He died in 1906 worn 

 out with the incessant ardour of research, when only forty- 

 six years of age. 



J. Bell Pettigrew, another of the visitors this year who 

 are no longer living, was Professor of Medicine and 

 Anatomy and Dean of the Medical Faculty in the University 

 of St. Andrews. He wrote much on the subject of animal 

 locomotion in walking, swimming, and flying, and made 

 careful studies of the physiology of wings in Insects, Birds, 

 and Bats. His volume on " Animal Locomotion " passed
