Mr. Jackson’s ‘ Remarks on Botanical Bibliography,’ published in 
this Journal for rst (pp. 167-177), may be read with profit in con- 
nection with the ‘Guide.’ We imagine that many will regret that 
Mr. J saith did 7 at once give us a new edition of Pritzel’s 
‘Thesaurus ;’ he could certainly have done so with very little more 
labour than he has expended bs ye this work; but it would then 
hardly have come within the scope of the publications of the Index 
Society, to which body botanist are indebted for this most useful 
volume. We occasionally miss a distinctly noteworthy book—e. g., 
Gaudichaud’s ‘ Ohgadoganid dae Végétaux ;’ but on the whole Mr. 
Jackson a been singularly satisfactory in his selection of im- 
portant books. 
Mueli:t care has evidently been taken in ascertaining when pos- 
sible the authors of anonymous or pseudonymous — ; thus the 
‘eminent botanist” who was advertised as having revised the 
second English edition of Figuier’s ‘ Vegetable World’ is 5 identified 
with Mr. Dyer, of Kew; ‘‘ Johannes Senilis,” who is actually quoted 
under this pseudonym by the authors of the ‘ Genera Plantarum,’ 
is shown to represent ‘J. Nelson ;” and many other works of less 
note are traced to their authors. urther information in this 
direction will doubtless be forthcoming: ¢.y., the little work 
‘ Botany Novices,’ published under the initials ‘ L. BiB
