ical index of North American fungi, illustrations of mushrooms, and 
the development of his already great herbarium. The bibliographical 
index had been started before 1880, and was intended to include all 
references to North American species of fungi. It was made in the 
form of a card catalogue, with the idea of ultimate publication. The 
magnitude of the undertaking may be realized when it is stated that 
at the time of Dr. Farlow's death the index included approximately 
350,000 references. A first part of the index was published in 1905. 
Then the botanical congresses held at Vienna in that year and at 
Brussels in 1910 led to the postponement of further publication in 
the hope that the nomenclature of the fungi would be put upon a 
stable basis which might be employed in the index. For the illus- 
trations of mushrooms, Dr. Farlow had employed the assistance of 
exceptionally skilful botanical artists and more than one hundred 
colored plates of great beauty and scientific value had been prepared 
and printed. It is to be hoped that the publication of both of these 
works may be possible in the near future. 
Dr. Farlow's keenness as a collector, his exhaustive knowledge of 
cryptogams, his wide acquaintance with botanists in all parts of 
the world, and his financial resources, all contributed to the building 
up of the most valuable cryptogamic herbarium and library in Amer- 
ica. Some account of the former was published in Ruopona (3: 
242. 1901). The large collections which are of special interest to 
New England botanists are Dr. Farlow's own collection of algae 
and fungi, the Edward 'Tuckerman herbarium of lichens, the Faxon 
Sphagna, and the moss-herbaria of T. P. James and of the late Dr. 
George G. Kennedy. Dr. Farlow's familiarity with the lower plants 
was only equalled by his knowledge of the literature of the subject. 
His letters from Europe in 1872-74 express his desire to collect a 
library in liis special field, and mention books that he was seizing 
the opportunity to buy. Of the richness of his library in recent 
years, only those can judge who have had the privilege of access 
to it. All botanists will rejoice that both herbarium and library 
have been left to Harvard University and that they are to bear the 
appropriate name of “ The Farlow Herbarium and Reference Library 
of Cryptogamic Botany." 
The recognition of Dr. Farlow’s eminence in his profession was 
wide-spread both in America and in Europe. The honorary degree 
of LL. D. was conferred on him by Harvard in 1896, by the Univer-
