NOTES.-ORIGINAL AND SELECTED. 
Derham’s Letters. —In the interesting series of letters which 
Mr. Barrett-Lennard has reprinted, there are one or two errors 
of transcription which are of consequence. In that dated 
3rd February 1704-5, printed on p. 175 (E.N. vol. xvii.) 
4 ‘ Ranwolff ” should be “ Rauwolff.” Leonhardt Rauwolff, 
of Augsburg, a pupil of Rondelet at Montpellier, travelled in 
the Near East in 1573-5, and his travels were published (in 
German) in 1583, a translation of which Ray edited in 1693. 
Rauwolff’s herbarium of some 500 specimens in four volumes 
became the property of Queen Christina, of Sweden, was given 
by her to Isaac Vossins, her Greek tutor, whom Charles II. made 
Canon of Windsor, and was bought at his death by the Univer¬ 
sity of Leyden, where it is still preserved. Gronovius described 
the plants and gave a life of Rauwolff in his Flora Orienialis, 
1755. Rauwolff died in 1576. 
The postscript to Derham’s letter should read :— 
“ I met also wth Ray’s Synops: methodica Quadrupedum et Serpent: 
Generis. At about 4s. I think it was. Tis in 8vo., and never had any 
Icons.” 
Derham and his learned contemporaries constantly use 
“ icons ” for plates or figures in books. Mr. Barrett-Lennard’s 
ingenious suggestion (p. 177), about bookbinders’ polishing irons, 
is, therefore, unnecessary.—(Prof.) G. S. Boulger, F.L.S., 
Richmond . Surrey. 
Elm Pipes for the Conveyance of Water. —Mr. T. V. 
Holmes send the following cutting from the reprinted notes 
from The Times of 13th May 1814 : — 
“ Notice is hereby given, that the Committee of Managers of the 
London-bridge Waterworks will meet there on Friday, the 20th May,

who may be willing to supply them with Elm Pipes, bored out of maiden 
elm, to be paid for in every third month. Such proposals to specify
