the tube down through the tissues of the style to and into the em- 
bryo-sac through the micropyle, but also evidence that the pollen- 
tube delivered the fertilizing or fecundating matter to the primor- 
ditm of the embryo (now called egg-cell or egg), already existing 
in the embryo-sac, fertilizing it, and thus initiating the development 
of the embryo. Prior to Amici’s investigations the German bot- 
anist, Schleiden, and others had held that the embryo arises in the 
end of the pollen-tube and is merely carried by it to the embryo-sac 
for further development. This wax model, in colors, is of very 
perfect execution, showing the histological details with great clear- 
ness. It is, of course, of the greatest historical interest and impor- 
tance. Without this discovery of Amici the whole modern sciences 
of genetics and eugenics would have been impossible. The model 
bears the following inscription: 
“ Preparasioni in cera demonstranti la fecundazione nella piante 
scoperta da Giovanni Pa ene e da lui esibite nella adunanza 
del / Octobre 1839 in occasione della prima Reunione degli Sci- 
ensiatt Italiani tenuta in Pisa. Opera dell’ artifici Luigi Calamai.” 
Among the plants of interest were a Maidenhair Tree (Ginkgo 
biloba), > tt an ee but now moribund; a Cedar of Lebanon 
(Cedrus libani), 5 ft. in diameter; a lovely clump of big Bamboo 
(Phyllostachys eer ce ; and a Magnolia grandiflora, 30 
inches in diameter. Grape vines were grown for the purpose of 
securing shade for other plants. The garden has, besides its sci- 
entific staff (a director and two assistants), one head gardener and 
5 gardeners. About 125 students of agriculture, medicine, and 
eae study each year at the garden. We were greatly in- 
debted to Dr. Ugolino Martelli, Professor in the University of 
Pisa and one of the assistants at the garden, who acted as guide 
and made our visit most pleasant and profitable.

The Genoa garden (Orto Botanico della R. Universita di Ge- 
nova), was established in 1803, a small garden along the north side 
of the Palazzo Universatario, under the directorship of Domencio 
Viviani until 1839, It was here that I'rederico Delpino, the third 
director (1872-1884), carried on his well-known and valuable 
studies on the cross-pollination of flowers. Here also Ottone
