212 THE PRESIDENTIAL ADDRESS. [Suss. uxxr. 
(1905) was Professor oi Botany in the University of Brussels, 
was elected a Corresponding Member of this Society in 
1893. He was quite the most distinguished of the Belgian ~ 
botanists. His work at first bore upon flower-pollination, 
but latterly he was entirely engrossed in the deep question 
of the excitation of protoplasm and its response to various 
extrinsic and intrinsic stimuli. In regard to this he pub- 
lished some valuable and suggestive papers. Errera’s visits 
to Britain were frequent. The meetings of the British 
Association often found him in attendance. He was conse- 
quently well known to British botanists, with whom his 
frank and cheery manner made him popular, and who mourn 
his premature decease with a strong feeling of personal 
loss. 
JOHN HORNE was a shrewd Scots gardener, one of those 
who the world over have compelled respect for the title and 
made it the synonym of excellence. From the Royal 
Gardens, Kew, he went to fill a subordinate post in the 
Government Botanic Garden at Pamplemousse, Mauritius. 
There his sterling qualities enabled him to rise to the 
position of Director, which he occupied for many years. 
During the period of his incumbency the preparation of the 
“Flora of Mauritius and the Seychelles” was undertaken at 
Kew by Mr. Baker, and the completeness of the published 
work was in great degree due to Mr. Horne, who not only 
added to the material already in the Herbarium at Kew 
from Mauritius but also made two botanical explorations of the 
Seychelles, and his collections formed the chief material for 
their Flora. A genial, hospitable man, he closed a successful 
career in Mauritius when he retired to St. Helier, Jersey, 
where he died in spring 1905. He was elected a Corre- 
sponding Member of this Society in 1887. : 
CHARLES Moorg.—The name of Moore has been a familiar 
one in the botanical and horticultural world for more than 
half a century through the life and work of two brothers— 
Dr. David Moore, for many years head of the Botanic Garden 
at Glasnevin, and Charles Moore, of whom I now speak. I. 
may interpolate here with satisfaction that the reputation of 
the name is still worthily maintained by Mr. F. W. Moore, who
