A UNIQUE COLLECTION OF ARITHMETICS 235 
printing up to 1830. The more general treatises on bibliography like 
those by Graesse and Hain and Copinger also touch this field, although 
of necessity only incidentally. 
Aside from these there have been some purely national works like 
the “ Bibliography of the Lowlands ” of the mathematical and physical 
sciences by Bierens de Haan and the “ Biblioteca Mathematica Italiana,” 
by Pietro Riccardi. Professor Smith’s “ Rara Arithmetica ” contains, 
for the period which it treats, more titles of Italian works than does 
Riccardi and more German than does Murhard or Rogg. In general, 
we may say, it is more complete for its specialty than any of the bib- 
liographies hitherto published. The “ Rara Arithmetica” may be said 
to be, with the exception of slight additions, the final bibliography of 
_ this field. It may safely be predicted that for centuries to come no 
other authority will appear to contest its claim to first place.
