REPORT ON A TRIP TO EUROPE. 
Dr. N. L. Britton, Director-in-Chief . 
Acting under instructions from the Board of Managers of the 
Garden, I was engaged in work in European herbaria during the 
past summer and I beg to present below a brief report upon the 
work there carried on. I sailed for Europe on June 4 with the 
purpose of visiting certain herbaria and museums where the his- 
torical ‘types’? of American marine algz are preserved, and of 
making a more or less critical study of such types. Specimens, 
chiefly of my own collecting in the West Indian region, were 
taken for comparisons with these originals. Provision, also, was 
made for photographing the types whenever it might appear that 
a photograph would be of essential service in future studies, and 
it is a pleasure to record that permission to take such photo- 
graphs was very courteously granted in every case in which it 
was asked. In addition to examining American materials from 
which species were first described, I was enabled also to see the 
European or other foreign types of various ee with which 
American plants have been associated. ith the idea of saving 
time and of facilitating the recognition of the taxonomic type, I 
had previously made out in card-index form a list of the types 
which I hoped to find at each of the places visited. On these 
cards, in addition to the original name and place of publication 
of the species was given the manner of citation of the original 
specimens, this usually by quoting the words used by the author 
in referring to the material that he had in hand.
