botanical readers to this truly classical: work. We have now to ané 
hounce the completion of this laborious undertaking, which forms per-

work is six thousand eight hundred and ninety-five; and the additions 
in the supplement (which occupies a part of the seventeenth a the 
eighteenth fasciculus) extend this number at least to'7000. ‘The 
edition of the» sommes Piaisarvies, by Linneus, (Stockholm, 1764,)
