Notes . 
With respect to the sentence quoted by Mr. Thiselton-Dyer from 
Dr. Bornet’s letter to prove that the existence of Mrs. Griffiths special 
collection of algae at Kew is accepted as a fact by critical algo- 
logists, we have Dr. Bornet’s permission to say that his authority for 
the statement is the following quotation from De Candolle’s Phyto- 
graphie : — ‘ Griffiths (Mad.) de Torquay, Algues britanniques : herb, 
royale de Kew, Rep. (1862); herb, de la Socidt£ Linneenne de 
Londres (3 vol. in fol.).’ 
Dr. Bornet adds in his letter to one of us (H) : ‘ La premiere de ces 
indications est confirmee par les auteurs du “ Bibliographical Index of 
British and Irish Botanists” quia paru dans le Journal of Botany, 
1889, vol. xxvii. p. 47, Griffiths, Amelia W., Algologist, Algae at 
Kew.’ [By James Britten, F.L.S., and G. S. Boulger, F.L.S.] 
It will be seen therefore that the foundation for the opinion of Dr. 
Bornet actually rests on the Kew Report, the statement in which, as we 
have shown above, is not in accordance with facts published elsewhere. 
III. In the same note exception is taken to our statement that 
Mrs. Gray’s specimens are in the Herbarium of the University of 
Cambridge, and the suggestion is made that the specimens alluded to 
by us are one of a series of sets made up by Mrs. Gray for distribution 
to various public institutions. 
The evidence on which our statement rests is as follows :■ — The 
Herbarium has been examined by one of us (H) and is evidently a 
large and valuable collection, containing as it does an extensive series 
of specimens of many of the species, and many rarities. We have still 
further confirmation for our statement in the following letter, bearing 
date May 16, 1891, received from Professor C. C. Babington, 
Professor of Botany in the University of Cambridge : — 
‘ We certainly have both Dr. and Mrs. Gray’s special Herbaria of Algae in the 
Cambridge Herbarium. It came through her executors.’ 
IV. It is pointed out 1 that the type-specimen of Ectocarpus fenes- 
trcitus , Berk., in the Berkeley Herbarium at Kew, has been lent to 
Dr. Bornet at his request and has proved to be identical with E. Lebelii , 
Crn., and it is assumed that the former species must therefore be 
discarded. This, however, by no means follows as a necessary 
sequence. 
Neither of us examined the type-specimen of Ectocarpus fenes-
