70 THE NEW ‘INDEX OF PLANT-NAMES.’ 
the original pagination is preserved, as in the American Academy, 
reference is easily made, but when, for instance, one of Grisebach’s 
plants which is to be found on a certain page of the Gottingen 
‘ Abhandlungen,’ you need to know the constant of difference in 
order to use the reprint. I need hardly explain it further, but 
i i ion :-—Ranunculu ] 
will be found o. n page 21; in this case the constant difference is 48. 
This practice of re-paging, with perhaps a a special title-page, 
leads to another troublesome retites a bbe ee the title of 
the paper, instead of its position in the s Hence time is often 
lost by looking®for a separate word ails a title, webct requires the 
+e. of the Royal Society’s Catalogue of Scientific Papers to make 
clear. The case just quoted shows this. Some excellent remarks 
on a which supply insufficient information as to their original 
source will be found in a footnote in Bull. Soc. Bot. France, v. 
(1858), 291 
Seed- sca are a terrible 1 oboe Ephemeral in their nature, 
any of the names they contain would have perished in our 
literature had they not bent: fiwublickeds in ‘ Linnea’ or the ‘Ann. 
Sci. Nat.’ They are so scattered and irregular that it seems 
impossible to gather up the new species from them, unless from 
some such codification as Dr. Urban has made for 1850-79 
Societies’ publications and oe have the year added ; is 
a great help to finding the reference, and an additional check to the 
citation. 
Local societies at home and abroad have issued sets of publi- 
mera which are frequently hard to find, or, if at hand, possibly 
imperfect. 
Sets of distributed plants are not indexed, unless taken up by 
someone with a diagnosis, and are ex _ through the publishing 
agent, e.g., Hochst. ea A. Rich. Fl. abyss., &c. 
Bare hames are noted, when no aia weno exists, with (nomen) 
appended ; oe description i is given anywhere else subsequently, the 
latter is _—— ed. 
great point should be made of citing works in an abbreviation 
of the actual title, and not by translation. To render ‘ Abhand- 
lungen, Verhandlungen, Afhandlingen , Transactions, Handlingar, 
&e.,’ by ‘Acta,’ makes it doubtful what series is — when 
referring to the catalogue of a large library. ‘Lam. Dict.’ is an 
ugly way of citing the work which formed a — ee the task of 
the French Encyclopedistes. Worse still is ‘ Pall. Iter.’, for 
ere we are in doubt as to what edition sure in what language. 
The original narrative was published in German, and if cit ited 
as ‘Reise’ we know that the original and not the French or 
English version is meant, which should be given as ‘Voyages’ or 
‘ Travels ’ respectively. 
It will be readily imagined that no long time was needed to 
show that, however desirable from the standpoint of accuracy, every
