224 JOURNAL OF THE ARNOLD ARBORETUM [vol.xxii 



which more definite dates of issue are as yet unknown^ other than the 

 inclusive period 1840-43, although it seems probable that they may 

 have been issued in 1841-42. 



For volume three it is now possible to add some supplementary in- 

 formation regarding the dates of issue from a fascicle cover^ and its 

 accompanying notice^ recently received at the Arnold Arboretum. Wight 

 states (Icones 6:viii. 1853) that parts one to three of this volume 

 appeared from 1843 to November 1845. The fascicle cover of number 

 one of volume three bears the printed date 1843, but it was clearly not 

 issued until 1844. In the notice accompanying this part, in explaining 

 the delay in the issue of his ^'Illustrations of Indian Botany/' Wight 

 states regarding the latter: ^^Immediately on publication of the last part 

 [of the ''IllusfrTtions''] published (Part 1, Vol. 2) he was under the 

 necessity of packing up the whole of his collections preparatory to 

 leaving Madras and up to the present hour, {May 1, 1844) [italics mine] 

 the greater part of them are unavoidably still in the packing cases." 

 Thus part one of volume three of the ^'Icones^^ could not have been 

 issued before May, 1844. As the list on the inside of the back cover 

 of the fascicle cover included plates 737 to 815^ we can safely assume 

 that the year of publication of these was 1844 (not 1843), and probably 

 in May of that year. For volume three, part three, plates 618 to 930, 

 and the text of plates 931 and 932, repeated in volume three, part two, 

 no additional data are available other than that the part was issued in 

 1844-45. Part three, including plates 931 to 1046, appeared in Novem- 

 ber, 1845 (Wight's own statement), and the remainder of the volume, 

 plates 1047-1162, in September, 1846=^ (again Wight's own statement). 



Summarizing we can thus narrow the dates of publication of the 

 parts discussed, as follows: 



Vol 1, No. 1, pll-20 (July?) 1838 



Vol 2, Part 1, pi. 319-416 1840 



Part 2, pi 417-514 1840-43 (probably 1841) 



Part 3, pi 515-631 1840-43 (probably 1842) 



Part 4, pi 632-736 1843 



Vol 3, Part 1, pi 737-815 (May?) 1844 



Part 2, pi 816-930 1844-45 



Part 3, pi 931-1046 (Nov.) 1845 



Part 4, pi 1047-1162 (Sept.) 1846

*Pritzel, G. a. Thesaurus literaturae botanicae ed. 1, 322, no. IU22, 1851, states 

 that volume three, parts 1 to 4, plates 737-1162, appeared in 1843-47. It has been 

 shown above that the first part, plates 737-815, couid not have appeared before 

 May, 1844, but the last part, plates 1047-1162, may not have been issued until 1847.
