478 BOTANICAL INFORMATION, 
upon the principle of Natural Orders, and, as a necessary 
consequence, to study general affinities, the relation of 
outward forms to anatomical structure and physiological 
distinctions, and to raise the standard of the science. I 
cannot but think that this change has been, in a great 
measure, the result of the success attending the zeal and 
activity of Parlatore in establishing the “ Central Italian 
Herbarium," at Florence, aided, as he has been, by the 
liberality of the reigning Grand Duke. 
From Florence, our first halt was at Pisa, where is one of the 
old Italian botanical gardens, still arranged according to the 
old Linnæan classes, it is true, but to which a large addition 
has just been made for the express purpose of adding à 
natural classification. The herbarium attached to the garden 
and belonging to the University, is chiefly that of the late 
Professor Gaetano Savi, and does not yet contain much 
besides Italian and garden plants. It is now under the 
direction of the present Professor Pietro Savi, son of Gaetano, 
and brother of Paul Savi, the Professor of Zoology, who 
is showing great zeal in the formation of tbe zoological 
museum, and has made beautiful preparations of the 
animals which have died at the menagerie. Under Professor 
Pietro Savi is an active young man, Dr. Tassi, assistant- 
director of the garden and herbarium: both are eager in the 
endeavoür at least to increase and determine accurately the 
collection. It is kept with more than even the usual com- 
plication of precautions, which have practically little effect 
besides increasing the difficulty ofconsultation. Plants, tnr 
. in double sheets, are well done up in bundles, between = 
. boards, each bundle enclosed in a wooden box, and the — 
boxes ranged on shelves. The library, though very ineffc — 
cient for a working botanist, contains many of the most 
. useful works for determining species. | uns P 
At Naples, the botanical garden is under the direction of uw
