JOURNAL OF THE ARNOLD ARBORETUM [vol. xxyih 



Desvaux's plan to issue four numbers of 48 pages each. It is worthy of 

 note that the set in the library of the New York Botanical Garden contains 

 pages 193 to 240 of the volume under discussion, this indicated as no. 5, 

 May, 1814. But a footnote on page 197 clearly indicates that it could 

 not have been published before February, 1816; see Hazen, Bull. Torr. 

 Bot. Club 56: 531. 1929. The fifth volume promised by Desvaux for 

 1815 never appeared. and apparently also only certain fugitive issues of 

 the last part or parts of volume three for 1814 were actually distributed. 

 I know of only the New York copy of vol. 3. no. 5, never having seen a 

 référence to an existing copy of no. 6. I have seen no fascicle covers of 

 any of the numbers of this second run of Desvaux's Journal de Botanique. 

 Apparently the unsettled conditions in Paris associated with the fall of 

 the first empire in 1814, and the first year or two of the restoration were 

 not conducive to regularity in publication of technical periodicals.
