were then dealt with, in Canada, the Adirondacks and Wyoming, 

 and abroad in Sweden and Norway. A series of analyses was 

 then presented on the screen, and the other relations of the var- 

 ious ingredients discussed, with special reference to replace- 

 ments, etc. 



The results of many analyses were shown in a remarkably in- 

 teresting chart, in which the relations of the components were 

 plotted in curves, and important deductions were made possible 

 to the view. 



Professor Dr. H. Lundbohm, of Sweden, was present and ad- 

 dressed the meeting by invitation. He expressed his great in- 

 terest in the paper of the Chairman and gave some additional 

 facts with regard to the titaniferous ores of Sweden. 



Mr. Kunz raised the question, suggested by the chart, as to 

 the replacement of phosphoric acid by vanadic in the apatites as 

 in the lead compounds. The Chairman had distinctly noted the 

 fact that the chart showed the two acids to be present in inverse 

 relations but was not aware that the replacement had ever been 

 recognized with lime, as with lead, and thought the vanadium 

 more probably present in some other association, perhaps with 

 the chromium. 



Another point, raised by Dr. Lundbohm, was treated, namely, 

 the especial superiority possessed by or claimed for some varieties 

 of iron made from titaniferous ores. The Chairman held that this 

 superiorityfor some purposes, such as car-wheels, might perhaps 

 be due to the presence of certain other elements associated in most 

 of these titaniferous ores such as small amounts of nickel, cobalt, 

 etc., rather than to the titanium, which is not generally regarded 

 as an advantageous ingredient. 



There is trouble and cost in working these ores, which have 

 thus far made the attempts in many cases unprofitable in com- 

 petition with cheap and easily worked ores from Lake Superior 

 and Alabama ; but there is no insuperable difficulty, and the 

 titaniferous ores constitute a great reserve supply for the future.
