6 FOREWORD. 



figures in pencil may be seen upon tlie sheets ; these are due to 

 the preliminary attempt effected in 1747-50, which is still pre- 

 served, see Dr. J. M. llulth's account of Linne's first sketch of 

 his 'Species Plautarum * in the Sven.sk Bot. Tid.^kr. vi. (1912) 

 627-631. 



The handwriting of Linno is simply copied ; where nothing is 

 added, it is his alone (the figures in the first column and the 

 running numbers of the genera excepted). The handwriting of 

 everyone else is shown by its being underlined, or in parentheses, 

 or brackets ; the cataloguer's comments are shown by an initial J. 

 Long sentences on the face or the back of the sheets are shortened 

 by omission of the middle, the beginning and the end being given 

 before the name or sign of the writer. Labels as a rule are not 

 copied, but the writer's name when known is given ; as the label 

 is open to the inspection of the enquirer, it does not need to be 

 set out. Amongst the Mosses will be found many additions by 

 James Dickson, who not only gave his opinion to Sir J. E. Smith, 

 but largely added to the material ; these are shown by the 

 initial D. ; the water-mark on these sheets is English. 



Many of the numbers written on the sheets by Linnc refer to 

 books, as, for instance, ' Flora lapponica ' and ' Flora suecica,' 

 though not specified ; others correspond to lists sent by corre- 

 spondents, such as Tulbagh (c/. Proc. Linn. Soc. 1917-18, SuppL), 

 Alstroraer (MS. of consignments in 1762, kindly supplied by 

 Dr. .T. M. Hulth), Allioni, Arduino, Sparrman and Thunberg, 

 though the last two are not available. 



A full account of the herbarium was issued in the Society's 

 'Proceedings,' 1911-12, Suppl. ; as fresh information has accrued 

 since that was issued, the introductory matter has been revised 

 and reprinted in the following pages, as a Supplement to the 

 ' Proceedings ' for 1921-22.
