6o4 APPENDIX A. 



" by express command of the Prince. At the Prince's command they showed him a little, 

 " but he supposed that there was much more that they had suppressed or not preserved. 

 " The attempt to purchase some of the works — the Elector had given Fabricius money for 

 " the purpose (30 nummos unciales) — proved unavailing, owing to the disagreeableness of 

 " Agricola's heirs. It is no doubt due to these regrettable circumstances that all the works 

 " of the industrious scholar did not come down to us." The " disagreeableness " was pro- 

 bably due to the refusal of the Protestant townsfolk to allow the burial of Agricola in the 

 Cathedral at Chemnitz. So far as we know the following are the unpublished or lost works. 



De Jure ei Legibus Metallicis. This work on mining law is mentioned at the end of 

 Book IV. of De Re Metallica, and it is referred to by others apparently from that source. We 

 have been unable to find any evidence that it was ever published. 



De Varia temperie sive Constitutione Aeris. In a letter' to Johann Naevius, Agricola 

 refers to having a work in hand of this title. 



De Metallis et Machinis. Hofmann* states that a work of this title by Agricola, dated 

 Basel 1543, was sold to someone in America by a Frankfort-on-Main bookseller in i8g6. 

 This is apparently the only reference to it that we know of, and it is possibly a confusion of 

 titles or a " separate " of some chapters from De Re Metallica. 



De Ortu Metallorum Defensio ad Jacobum Scheckium. Referred to by Fabricius in a 

 letter' to Meurer. If published was probably only a tract. 



De Terrae Moiu. In a letter'" from Agricola to Meurer (Jan. i, 1544) is some reference 

 which might indicate that he was formulating a work on earthquakes under this title, or 

 perhaps may be only incidental to the portions of De Ortu et Causis dealing with this subject. 



Commentariorum in quibus uiriusque linguae scriptorum locos difficiles de rebus 

 subierraneis explicat, Libri VI. Agricola apparently partially completed a work under some 

 such title as this, which was to embrace chapters entitled De Methodis and De Demonstratione. 

 The main object seems to have been a commentary on the terms and passages in the classics 

 relating to mining, mineralogy, etc. It is mentioned in the Preface of De Veieribus et Novis 

 Metallis, and in a letter^' from one of Froben's firm to Agricola in 1548, where it is suggested 

 that Agricola should defer sending his new commentaries until the following spring. The 

 work is mentioned by Albinus'^ and in a letter from Georg Fabricius to Meurer on the 2nd 

 Jan. 1548," in another from G. Fabricius, to his brother Andreas on Oct. 28, 1555,'' and in 

 a third from Fabricius to Melanchthon on December 8th, I555^^ in which regret is expressed 

 that the work was not completed by Agricola.
