very soon to make a thorough test of the new ‘projection’ oculars of Zeiss, in combi- 
nation with the apochromatic objectives of the same maker. 
After those present had duly inspected the details of the exquisitely-finished instru- 
ment, a demonstration of its practical working was given by taking a photograph of a 
stained section of the eye in the embryo of the calf. The plate was given an exposure 
of eight minutes and, notwithstanding the unfavorable conditions caused by the crowded 
room, the resulting negative was, upon development, found to be excellent. A number 
of prints from negatives of other subjects were handed around, and were examined with 
much interest. Several histological preparations were also shown under the microscope, 
with a novel monochromatic illumination. 
The proceedings terminated with a cordial vote of thanks to Dr. Ferrer for his interest- 
ing demonstration. A. H. BRECKENFELD, ec. Sec.

At the 52d regular meeting the paper of the evening was by the president, Dr. Seaman, 
and was on marine alge. Prof. Seaman said:—My purpose this evening is only to 
supplement Prof. Burgess’ very interesting paper on fresh-water algee with some remarks 
on particular relations of certain marine algz, and to exhibit the specimens I now lay 
before you. Marine alge are particularly fond of arocky bottom. Except the Saxgas- 
sum, which floats in the water without attachment and forms the well-known mass in 
the central portion of the Atlantic ocean, but few species are found in large quantities 
away from the rocks. Hence on our Atlantic coast south of New York, although the 
diligent collector might gather almost as many species in very small quantities, the total 
bulk of algze is extremely small compared with what are found on the New England 
coast. Especially is this the case if we add, to the rocky bottom, the great area alter- 
nately exposed and covered with water by the extremely high tides of our northeastern 
coast. Along the shores of the Bay of Fundy I have seen hundreds of acres thus con- 
ditioned covered with a heavy burden of /zcus vesiculosus, on which sheep pasture in 
winter without any care save to warn them off the rocks in time to escape the incoming 
tide. In cold and stormy weather they retire to the dense hackmatack swamps, and 
thus thrive with far less care than the flocks of the middle State farmer. Along the 
shores of Maine the country people flock to the shore at the proper time for miles around 
to gather the Chondrus crispus that makes an extremely delicate and delightful blanc- 
mange. On the same coast may be found some of the great Laminarias which on the 
N.W. coast grow to such anenormous size. Those I have seen were likea broad-bladed 
oar with very little handle, and some of them from 25 to 30 feet in length. The stem 
in such cases would be as thick nearly as my wrist, and when cut in pieces may have the 
tangs of knives inserted and dried on, making a fairhandle. Muchless care is required 
in mounting the marine alge than is necessary with the fresh-water species, as their 
consistence is somewhat greater. So highly is their beauty appreciated that some ladies 
living near the sea-coast summer resorts of New England make quite a business of pre- 
paring specimens of these ‘flowers of the sea’ for sale to those who admire them as 
ornamentsonly. The paper was illustrated by a portfolio containing above sixty of the 
most beautiful and delicate forms. Ee Al BALLOCH wtec. Serr

The first annual soiree was held at Greyhound Hall, Nov. 24, 1886. A very large 
number of exhibits were reported and a large number of different instruments. Besides 
the usual interesting objects exhibited on such occasions there were shown: Embryo 
chick—6o hours’ incubation ; bolting cloth ; fresh-water Rhizopods ; itch insect ; sozo- 
dont tooth-powder, composed of diatoms from Keene, N.H.; Bacillus cholera Asiatica ; 
micrococcus rabies, or germs of hydrophobia; method of enumerating blood-corpuscles; 
native-gold crystal; circulation of blood in tail of fish ; willow-blight in place; broken 
spore fruits of willow-blight ; eye of lobster; crystals of maple-sugar; anchors and plate 
from Synapta.
