of whom, e.g. Lofling, many letters are preserved in Linne's 

 corresponilence, and this valuable body of letters has been 

 constantly appealed to for information or confirmation. 



Plan of (1912) Index. 



The method of framing the index was as follows. A list of 

 all names of genera and species issued by Linne was drawn up, 

 cliielly from Petermann's Index to E.ichter's ' Codex Linna^anus,' 

 with some additions and corrections. The herbarium was then 

 examined sheet by sheet, and the Linnean names marked against 

 the list. Many manuscript ami unpublished names have been 

 fountl, aiul are distin^niished by the aflix (MS.) ; further, a fair 

 number of species which were published in the ' Supplementura' of 

 the younger Linnd in 1781, have been marked as in (Suppl.). 

 These last are of interest as making certain wliich species were 

 described by the elder Linne, al)out 189 in all, for the book itself 

 gives no clue as to autliorship. I may remark parentlietically, tliat 

 the manuscript of the ' yupplemenlum' sheds but. little light ui)on 

 this question, as the earlier part has' been copied by another hand, 

 and practically none of it remains in the handwriting of Linnc. 



Earlier Enumerations. 



The next step was to collate certain enumerations existing in 

 Linne's writing. 



1. An interleaved copy of 'Species Plautarum ' ed. 1, 1753, 

 in which the number before each species then possessed by Linnc 

 is underscored. This was copied by Jonas Dryander in or about 

 1785, wlien the Linnean and Banksian herbaria were collated 

 (Proc. Linn. Soc. 1887-88, p. 28; Smith in Linn. Lachesis, pref. 

 p. ix.). A transcript of this copy is also at Kew (Proc. Linn. 

 Soc. 1906-7, p. 91). I found in the Linnean copy that the printed 

 pages 849-856 inclusive had been cut out, the interleaves alone 

 remaining; as tlie Banksian copy has no marks on the corre- 

 sponding pages, it is clear that these pages were already missing 

 when the Linnean books came into the possession of Smith. 



2. A manuscript list described in the ' Proceedings ' 1906-7, 

 pp. 90-95 : it was brought down to the spring of 1755, most of 

 the marking being by dots prefixed. 



3. A copy of the second volume of the twelfth edition of the 

 ' Systema jVatur»,' 1767, the numbers of the species represented 

 in the Linnean herbarium being underscored as in No. 1. 



The collation of these tliree Linnean lists, with the actual 

 noting from the herbarium as it now exists, permits of a few 

 observations being made. Each of these lists is faulty; the third 

 especially so, for such genera as AliJura, Phlomis, and Pulmonaria 

 have escaped marking altogether ; pages 408 and 409 have been
