stride of advance over anything previous, that they merit careful consideration. 



Eyn Nutzlich Bergbuchlin. Under this title we frequently refer to a little booklet on 

 veins and ores, published at the beginning of the i6th century. The title page of our copy is 

 as below : 



btfcblm von alien a&eta 



vom (kuecfftlber. 



This book is small 8vo, comprises 24 folios without pagination, and has no typographical 



indications upon the title page, but the last line in the book reads : Gedruckt zu Erffurd durch 



Johan Loersfelt, 1527. Another edition in our possession, that of " Frankfurt am Meyn", 



1533. by Christian Egenolph, is entitled Bergwerk und Probierbuchlin, etc., and contains, 



besides the above, an extract and plates from the Probierbuchlein (referred to later on), and a few 



recipes for assay tests. All of these booklets, of which we find mention, comprise instructions 



from Daniel, a skilled miner, to Knappius, " his mining boy". Although the little books of 



this title are all anonymous, we are convinced, largely from the statement in the Preface of 



De Re Metallica, that one Calbus of Freiberg was the original author of this work. Agricola 



says : " Two books have been written in our tongue : the one on the assaying of mineral sub- 



' stances and metals, somewhat confused, whose author is unknown ; the other ' On Veins', 



' of which Pandulfus Anglus is also said to have written, although the German book was written 



' by Calbus of Freiberg, a well-known doctor ; but neither of them accomplished the task he had 



' begun." He again refers to Calbus at the end of Book III. 2 of De Re Metallica, and gives 



an almost verbatim quotation from the Nutzlich Bergbuchlin. Jacobi 3 says : " Calbus 



' Fribergius, so called by Agricola himself, is certainly no other than the Freiberg doctor, 



' Riihlein von C(K)albe." There are also certain internal evidences that support Agricola's 



statement, for the work was evidently written in Meissen, and the statement of Agricola that 



the book was unfinished is borne out by a short dialogue at the end of the earlier editions, 



designed to introduce further discussion. Calbus (or Dr. Ulrich Riihlein von Kalbe) was a very 



active citizen of Freiberg, having been a town councillor in 1509, burgomaster in 1514, a 



mathematician, mining surveyor, founder of a school of liberal arts, and in general a physician. 



He died in 1523.* The book possesses great literary interest, as it is, so far as we are aware,
