* 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. 
n > 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. 
o The expansion of the lower end may probably be due to the cracking of the metal, which wa» 
greatest at that part. 
p Figs. 17,18,19. There was an increased thickness of metal at e.
