INTELLECTUAL ENJOYMENT FROM THE ASSOCIATION.

differing from another will alter the 
velocity of its wave, and thus the waves 
near the sides will move slower than 
near the centre of the canal, if the side 
he shallower than the middle. How, 
then, have these facts their application 
to the phenomenon observed ? Thus, 
in the experiment described above the 
velocity of the wave, ascertained by 
numerous experiments, was eight miles 
an hour. As long, then, as the boat 
moved at three, four, five, six, or seven 
miles an hour, it remained in the rear 
of the wave, the wave had no effect on 
it, as the law of the velocities was the 
theoretical law. At eight miles an hour 
the boat was, in point of fact, on the 
wave, and it might, indeed, be seen 
about the centre of the boat lifting it out 
of the water and diminishing the trac- 
tion upon it. — (See Section A, Tuesday.) 
The reading of this paper was follow-

Whewell, Professor Moseley, and Dr 
Lardner took a part, and the meeting 
adjourned. 
PUBLIC DINNER AT THE HOR-

Nearly 500 persons were present. Dr.

the 
GENERAL MEETING AT THE THEA- 
TRE. 
Soon after the doors were opened the 
house was filled — gallery, pit, boxes — 
from the top to the bottom ; and it is 
presumed that not less than 2,000 persons 
must have been present. At eight 
o'clock the Rev. Dr. Lloyd, Provost of 
Trin. Coll. Dublin, took the chair, as 
President of last year’s meeting. He 
soon after came forward, and thus ad- 
dressed the assembled members : — 
My Lords and Gentlemen. — Ever 
since the origin of this Association, I 
have looked forward to its annual meet- 
ings in the assured expectation of the 
highest intellectual enjoyment; and it 
is scarcely necessary for me to add, that 
in these delightful anticipations I have 
never been disappointed. Indeed, when 
I consider the purposes for which you 
are associated, and the powers by which 
those purposes are to be effected, it 
would seem to me impossible that any 
hopes of this kind, however sanguine, 
should end in disappointment ; — for here 
it is my unspeakable privilege to mix 
with the elite of this great country — with 
all that are distinguished by talents and 
attainments in each of the numerous 
departments of science ; and not more 
distinguished by those high qualifica- 
tions, than they are by the exalted pur- 
poses for which they are met together. 
Those purposes are, by a more rapid 
and extensive communication of the 
lights of science as they are struck out, 
and by carrying these things home to 
the doors of all, to awaken to exertion 
those gigantic powers of mind, which 
are not confined to a few favoured spots, 
but which are everywhere to be found ; 
and by establishing a more immediate 
and intimate communication among 
those engaged in kindred pursuits — to 
unite their exertions, as it were, into one 
simultaneous effort, and thereby to ac- 
celerate the progress of discovery in 
every line in which the mysteries of na- 
ture may be penetrated by the ingenuity 
and perseverance of man. 
Leaving to others to seek their intel- 
lectual entertainment in the way most 
agreeable to their own tastes, the efforts 
of this Association are directed to the 
investigation of those realities by which 
we are surrounded; and of the power 
with which they are invested, which, 
whilst they point to the being and the 
attributes of the One Great Source of 
all Existence, whom to know is to adore, 
do also constitute the means which He 
has placed within our reach, and in our 
hands, for the improvement of this our 
present condition. 
This is a labour in which all of every 
grade are alike interested, and in which 
all will, at least, bid you God speed. 
Accordingly, it will be observed, that
