'Petri published an excellent treatise, which went through four [recte five] editions. It deals with arithmetic and 

 geometry, as well as with book-keeping, and treats the subject succinctly and well. The improvements in the matter of 

 stock-taking and of making a periodical trial-btlance are incorporated. . . . Petri introduces for the first time two 

 important departures from the older methods. . . . He no longer journalises all transactions seriatim, but occasionally 

 groups the kindred items . . and takes a step towards the separation of the books of primary entry. He introduces an 

 ' Expenses-Book ', and at the end of every month transfers the total to cash account by means of the journal. . . . Petri's 

 book is truly one otprhnary entry.' Richard Brown. 



The above edition was unknown to Mr. Brown, who only quotes those of 1588, 1595, 1506, and 1605. Prof, de Morgan 

 only knew that of 1596.

Copies having the portrait are especially rare. It is different from that in the Fodinx'and. less comely, as he has 

 developed an aggressive Roman nose. The above copy is unusually tall, and probably on Large Paper, although Lowndes 

 does not mention such.

 Mines), folio, old calf (small part of blank margin torn out of portrait, but A LARGE AND SOUND 

 COPY) ; VERY RARE, 2. 12s Qd T. Basset, 1670 



This rare work is very valuable for giving an account of the state of mining in England during the XVIIth. Century. 

 It was undertaken at the request of Prince Rupert and Lord Shaftesbury. Large extracts from it are given in Hunt's 

 'British Mining'. 



The fine portrait is to be found only in a few copies of the work, it having evidently been subject to the ravages of the 

 grangerizer or print-seller of the past. It is of a much earlier period of his life than that to the ' Fleta Minor ' (supra), 

 and is not mentioned in D. N. B.
