need of greater development of this branch of equipment is 
increasing. The book market is still in a demoralized 
condition on account of the European conflict, but several 
thousand dollars could be expended advantageously in the 
purchase of books for the library even under existing cir- 
cumstances. 
Five parts of North American Flora, aggregating 448 
pages, have been issued during the year: Volume 9, Part 5, 
in June, Volume g, Parts 6 and 7, in October, Volume 21, 
Part 1, in November, and Volume 34, Part 3, in December. 
Another part is in press. ‘The issue of Part 7, completing 
Volume 9, was a noteworthy event in the history of this 
publication, as this is thus the first volume to be finished 
(see the November number of the Journal). 
The new periodical provided for by the will of the late 
president of the Garden, Judge Addison Brown, comprising 
colored illustrations of plants, each accompanied by text 
written in popular language, was launched this year as a 
quarterly publication. One volume of Addisonia, of four 
numbers each containing ten plates, has appeared, under 
the editorship of the Bibliographer and Head Gardener. 
Its reception by the public has been very gratifying, the 
number of subscriptions already amounting to 220. 
The Bibliographer has continued his work upon the 
literature of botany, and his taxonomic studies. His paper 
presented at the anniversary celebration last year, ‘“Seg- 
regation of genera in Lentibulariaceae,”’ was published in 
the sixth volume of the Memoirs, in September of this year; 
and he contributed to Volume 9 of North American Flora a 
32-page bibhography recording all the authors, books, and 
papers cited in that volume. He also gave a lecture in 
the public summer course of the Garden. 
Respectfully submitted, 
OHN HEenpDLEY Barnuart, 
Bibliographer.
