" It is certainly an extremely rare thing for a reviewer tobe called upon to notice a volume 

 measuring but a^. in, by.xf in., yet these dimensions faithfully represent the size of the handy 

 little book before us. The volume — which contains xi8 printed' pages, besides a few blank 

 pages for memoranda — is, in fact, a true pocket-book, adapted for being carried in the waist- 

 coat pocket, and containing a far greater amount and variety of information than most people 

 would imagine could, be compressed into so small a space. .... The little volume has been 

 compiled with considerable care and judgment, and we can cordially recommend it to our 

 readers as a useful little pocket companion." — Engineerins.
