194 PROCEEDINGS OF SOCIETIES. 
Mr. Archer showed some fine living examples of Volvow globator, 
and stated he had taken some of this beautiful organismin 
summer vigour and condition every month in 1865 since April 
last, and in January and March, 1866. He had not visited the 
pond in February, 1866, but he entertained no doubt, from 
getting a copious gathering in December and January, and 
another in March, but that he should have met it had he looked 
for it. He thought it seemed almost as if the history of Volvox 
was, so to say, inverted last year. In May, 1865, he took it in the 
“autumnal” state, that is, as the guondam “ Volvox aureus,” and 
then, also, specimens showing the remarkable polymorphous con- 
dition of the gonidia ; and in winter he took it as vigorous and as 
normal, but not so abundantly, indeed, as it usually presents itself 
in spring or summer. As it seems to be generally held that the 
active motile “summer” characteristic condition of this plant 
does not present itself in the winter months, Mr. Archer thought 
that this notice of a fact, seemingly new in itself, might, perhaps, 
possess some interest. 
Hackney Microscopican SorRkeE. 
A Microscopic Scientific and Artistic Conversazione was held at 
Pembroke Hall, Lamb Lane, Mare Street, Hackney, (Dr. Christie 
haying lent the hall for that purpose) in aid of the funds of the 
Hackney Working Men’s Institute. 
An appeal was made by the committee of the said institute, 
through Mr. W. L. Freestone and Dr. Millar, to the Council of 
the Microscopical Society, for their assistance and co-operation, 
which appeal was announced by the President to the meeting 
held in March last, which was most cordially responded to, and a 
high-class entertainment was the result, which was patronised by 
a considerable attendance of the first families of Hackney and 
Clapton, and ably supported by many distinguished members of 
the microscopic and other scientific societies of London; and on 
the first evening James Glaisher, Esq., F.R.S., was present. All 
the principal microscope makers were represented, viz., Messrs. 
Ross, Smith & Beck, Baker, Crouch, Steward, Browning, Salmon, 
Bailey, &c. There were shown altogether about sixty micro- 
scopes, and many works of art and articles of vertt were exhibited, 
several cabinet stereoscopes, a fine selection of glass slides, and 
also a variety of beautiful objects, living and prepared, amongst 
which may be mentioned— 
Dr. Millar exhibited the eggs of an insect of elaborate form. 
Charles Tyler, Esq., F.L.S., many interesting specimens of 
sponge-spicule, &e. : 
Henry Lee, Esq., F.L.S., marine zoophytes, Echinide, and a 
fine specimen of the Tsetse. 
Dr. Christie, a slide of Trichina spiralis in human muscle, pre- 
pared by W. L. Freestone. ‘
