494 Miscellaneous. 
Addenda et Corrigenda to Part J. (‘Annals,’ April 1901, 
pp. 390, 391). 
‘Voyage aux Indes orientales.’ 
By an oversight our first instead of our final conclusions were 
transcribed. It is evident that the sheeting as given by the Bibl. 
Franc. is wrong, that the latter half of the work came out in 
well-defined sections, and the last three livraisons were— 
Livr. 6. Pp. 337-440 (Fish & Mollusca). 1832. 
We 441-512 (Insecta). 1833. 
8. 513-end (Zoophytes & Index). 1834. 
‘Voyage au Pole Sud.’ 
Botanique, tom. i. Some copies have a titlepage dated ‘‘ 1842— 
1845.” This was an error of the publishers, as citations in the 
volume show, and the title in question was evidently withdrawn 
later. Its date was 1845. 
‘ Voyage sur la Bonite.’ 
Add :—Géologie et Minéralogie. Par M. E. Chevalier. Date as 
on titlepage 1844 (Compt. Rend. Acad. Sci. Paris, tom. xix. Sept. 16, 
1844, p. 583). 
Corrigenda to my Papers ‘‘ Note on Diatoms from Chincha Guano ” 
(Ann. & Mag. Nat. Hist. vol. vi., 1900) and “A List of Cali- 
fornian Diatoms” (1. c. vol. vii., 1901). By C. Mrrescuxowsky. 
I REGRET to say that the dimensions of the diatoms described in the 
two above-mentioned papers are not quite correct. Through an 
error in my calculations, which I discovered only lately, all the 
measures given are 5 per cent. higher than they ought to be *. 
In order to make it possible to correct this error I give here a table 
containing all measures quoted in both papers, accompanied by their 
real yalue. This will enable a quick and easy rectification‘.

* This applies also to the measures given in my paper “ Ntudes sur 
V’Endochrome des Diatomées,” which has recently been published by the 
Academy of Sciences of St. Petersburg. 
+ A few measures quoted from other authors need, of course, no 
rectification,
