April 20. The Society held a Scientific Assembly in 
Biological Hall of the University of Pennsylvania, from 
7.30 to 11 o'clock. A large gathering of members and friends 
of the Society was in attendance, and the rooms of the 
department, the greenhouses and the vivarium were lighted 
up. Numerous addresses, demonstrations and botanical 
exhibits were made by twenty-two members and outside 
contributors. The financial proceeds of the Assembly were

October 5. Dr. Miller, President, in the chair. 
Professor Macfarlane spoke on “The Flora of the Vol- 
canic Mountains of Clermont and of the Maritime Alps.” 
He described the botanical results of the excursions made 
from Clermont to the Puy de Pariou and the Puy de Dome, 
and explained the relation of the different types of volcanic 
soil to the wild and cultivated plants observed. Special note 
was made of the varied and rich coloring of the sub-Alpine 
vegetation on the top of the latter mountain. The flora of 
the French Maritime Alps near Arles, also eastward from 
this and within a few miles of Genoa, was xerophytic, except 
in the immediate neighborhood of the watered valleys. The 
xerophytic plants fell under three varieties: (1) a small, 
stunted type, with wiry, often spiny leaves; (2) plants of 
varying size, abundantly provided with glands bearing 
essential oils, many of these being referable to the orders 
Cistacee or Labiate; (3) hair-covered’ plants that were 
often quite woolly in texture. Numerous specimens of these, 
recently arranged by the speaker for the University Her- 
barium, were exhibited. 
Dr. Henry S. Conard then spoke on “New Hybrid Water- 
Lilies,” which had been raised by him during the year in the 
greenhouses and ponds of the Botanic Garden. The first
