NICKEL AND COBALT.

thermore, heat was applied from above. The results attained were very- 

 satisfactory, and assign to nickel and cobalt atomic weights varying from 

 each other by about a unit ; Ni being nearly 58, and Co about 59, when 

 O = 16. The exact figures will appear later. The cobalt results agree 

 remarkably well with those of AVeselsky. The following are the data
