' Petri published an excellent ti-eatise, which went through four {ncti' Jive] editions. It deals with arithmetic and 

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

 stock-taking and of making a periixlical trial-bilance are incorporated. . . . Petri introduces for the lirst time two 

 important departures from the older methods. . . . He no longer journalises all transactions serUdim, 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 montli transfers the total to cash account by means of the journal. . . . Petri's 

 book is truly one of priniary entry.' — Richard llrown. 



The above edition was unknown to Mr. Brown, who only quotes those of 1588, 1595, 16D(5, and lOOJ. Prof. <le Morgan

 CEPTIONALLY LARGE COPY in contemporary English ca//" (rare), £3. 3* 



printed for the author, by Thomas Dawks, 1683 

 Copies having the portrait are especially rare, it is different from that in the Fodiiix 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.

This rare work is verj 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. It.
