[March 5, 



Remarks. 



a The width was unaltered, and the thickness of the upper edge slightly increased. 

 Figs. 1 and 2. b Fig. 4. c Fig. 5. d Fig. 6. e Fig. 7. f Fig. 8. 



B The fibre opened at the fifteenth cooling. Fig. 9. 



h The fibre opened at the fifteenth cooling after having exhibited a slight crack 

 for two or three previous coolings. Fig. 10. 



1 The thickness of the metal at the indentation on ends increased -1". Fig. 11. 



k The thickness of the metal at the indentation on ends increased similarly to 

 the last. Fig. 12. 



1 Cooled in air 15 times. Cooled in water 10 times. 



m The ends became slightly rounded. Fig. 13. 



n At the last cooling the lower end of the cylinder began to crumble away in 

 the water. Fig. 16. 



The expansion of the lower end may probably be due to the cracking of the 

 metal, which was greatest at that part. 



p Figs. 17, 18, 19. There was an increased thickness of metal at e. 



q Figs. 20, 21.
