and a set of Guadeloupe algae distributed by Mazé were of special 
interest. In the collections of the Royal Gardens at Kew are 
some of the algae from the herbarium of Dawson Turner, au- 
thor of the classical volumes usually referred to as the “ His- 
toria Fucorum.” The algae secured by the Challenger Expedi- 
tion are also to be found at Kew. Advantage was taken of the 
excellent libraries of the British Museum and of the Royal Gar- 
dens to consult several publications which are not yet accessible 
in New York. The Linnaean herbarium, as is well known, is a 
rather unsatisfactory one from the standpoint of the type-hunter, 
nevertheless, it was interesting and edifying to glance over some 
of the specimens which we have reason to believe once passed 
under the eye of the “ Father of Botany.” 
After a brief visit to the Dillenian herbarium at Oxford, I went 
on to France, where the first stop was at Caen. In the herbarium 
of the Institut Botanique of Caen are found the collections of 
several well-known students of the marine algae, but those of 
Lamouroux, who wrote chiefly between 1805 and 1821, were of 
special interest. The probable types of thirty or more species 
drawn, At Paris, in the herbarium of the Muséum d'Histoire 
Naturelle, three weeks were devoted to studying and photo- 
graphing some of the algae described by. Montagne, by De la 
Pylaie, and by Decaisne. Bachelot de la Pylaie proposed a con- 
siderable number of new specific and varietal names for the kelps 
and rockweeds of St. Pierre, Miquelon, and Newfoundland, 
which region he visited in 1816 and again in 1819. Montagne 
was the first describer of numerous American species, particu- 
larly from the West Indies. At the Muséum, I saw also a set 
of the second edition of Mazé and Schramm’s Algae of Guade- 
loupe. The original materials used by the brothers Crouan in 
making the determinations on which Mazé and Schramm’s ‘‘ Es- 
sai de Classification des Algues de la Guadeloupe” * was based

A copy of one of the earlier editions has come into the possession of the Gar-
