Preface, p. ii. 
113 “This kind of pyrites miners call cobaltum , if it is allowed to me to use our 
German name. The Greek call it cadmia. The juices,, however, out of which 
pyrites and silver are formed, appear to slifify into one body, and thus is pro¬ 
duced what they call cobaltum . There are some who consider this the same 
as pyrites, because it is almost the same. There are some who distinguish it 
as species, which please me, for it has the distinctive property of being ex¬ 
tremely corrosive, so that it consumes the hands and feet of the workmen, un¬ 
less they are well protected, which I do not believe that pyrites can do.” 
(Bermannus, p. 459.) Hoover’s Engl, transl. of Agricola, De re metallica, 
p. 113. Hoover adds: “It is desirable to bear in mind that the mines familiar to 
Agricola abounded in complex mixtures of cobalt, nickel, arsenic, bismuth, zinc, 
and antimony. Agricola frequently mentions the garlic odour from cadmia 
metallica which, together with the corrosive qualities mentioned below (above) 
would obviously be due to arsenic.”
