26 
of Suffolk, because the former contained many genera not to be found in 
the latter, and indicating warmer clitnatal conditions. In the Channel 
Islands were three genera and three species, all belonging to the Lusita- 
nian type, and not found on the British coast, which would be pronounced 
to be from the Mediterranean, if shown to a continental naturalist. 
The President, after remarking upon the philosophical manner in 
which Mr. Jordan had treated his subject, observed that it was as difficult 
to draw true conclusions from exceptional, as from so-called general 
grounds. He described Prof. Forbes' experiments on bathymetrical zones 
in the iEgean Sea, which established the general rules, exceptions to which 
Mr. Jordan had that evening been pointing out. It was true, for example, 
that the Terebratula, usually a deep-sea shell, was sometimes found in the 
Littoral zone, but., as a general rule, where these shells abounded in any 
stratum, it was fair to call that a deep-sea deposit. There were many ex- 
ceptional cases, also, with the larger Carnivora. 
The meeting was closed with the usual votes of thanks to the authors 
of the papers, and the announcement from the chair that this was the last 
ordinary meeting of the Session, the annual meeting being held in May 5 
to be followed by the Summer Excursion meetings. 
MEETINGS OF SECTIONS. 
ENTOMOLOGICAL SECTION. 
Tuesday, April 10.— Mr. Stephen Barton, President of the 
section, in the chair. 
After the minutes of the previous meeting had been read, the President 
stated that he found upon inquiry that if the magazines were presented to 
the Society, the section would be able to have access to them for reference 
at any of the meetings of the section. It was therefore resolved that the 
volume of both the magazines, when completed, should be bound by the 
section and presented to the library of the Society. 
It was then resolved that the first monthly excursion should take place 
on Monday, May 7th, to Leigh Woods, the members to meet at the 
Clifton side of the Suspension Bridge at half-past 3 o'clock in the after- 
noon. Weekly meetings for collecting were also arranged for Saturday, 
April 21st, to Leigh, members to meet at the Suspension Bridge at 6.30 
p.m. ; for Thursday, April 26th, to the Boiling Wells, Stapleton, to meet 
at the Mill, near the Ashley-hill Station, at 6.30 p.m. 
CHEMICAL AND PHOTOGRAPHIC SECTION. 
Wednesday, April 11. — Mr. P. J. Worsley, F.C.S., President 
of the section, in the chair.
