The LinD1an society met on Saturday
afternoon in the ante room Of the museum
s. NJ. Sener, esq. was called to the chair,
and Mrs. l.. N. Zcll was appointed secre-
tsry pro tenn.
Tho following donations and additions
were made to the museum and library:
From Doctor NJ. l.. Davis large speci-
men OF Vdnddiuna, which 10 obtained from
Mr.. Hathaway, the owner aud discovcrer
vi the mine from which it was obtained
at TiOga, Pa. Mr.. H. is a blacksmith by
occupation, and experimenting with the
ore, he found that when melted with iron
aud copper, it rendered the former rs
hard as steel, and the latter few de-
degrees softer. He had razor blade made
from An old stove crate mixed
with this ore, and on melting
them together in crucible, then
beaten into shape on an anvil, the
metal became firm in texture. and admit
ted of . very high polish. Ndnadium was
discovered by SefstrOm in 1880. Some
authors have attributed j. TO Del Rio in
1901, but the former by whom it was
named after Vanadis, Scandinavian
deity, was the original discOverer. The
metal is found in nearly all clays in small
quantities, but its most abundant source
is the Eanadiats Of Lead, which has been
found in Scotland, Mexico and some of the
South American states. The metal may
be chemically obtained by the reduction Of
Vanadic acid, in the form Of brilliant
powder, having silvery lustre. It is
not acted upon by sulphuric Or nitric
acids, but nitrO-muriatic acid dissOlves it,
the solution resembling an acqueOus solu.
tiOn of sulphate of copper. Daua dc
scribes Tanadinite, or vanadate of lead
(Vanadinbleierz) as chrysta!izing hexa-
gOnally, but mostly occurring in implanted
glObules or incrustationS he is also ono
of the authorities who attribute it's dis
covery at Zimpana, in Mexico, by Del
Rio. This ore has dark brown or brown-
ish black color, add is generally observed
only in an earthly state, much like ferru-
ginOus clay. 1t is an Interesting fact that
it is now found in the state of Pennsylva-
mia.
An interesting little fresE-water fish, by
DIR. M.L.Davis. This is the B0leosoma tcsse-
laeunl, locally called the "Sand PERCH"
but it belongs to the family EtheostomidG,
which is only remotely related to the true
Percidg. This fish is remarkable for be-
ing destitute of an air. bladder, hence it is
always observed lying upon the bottom of
the pool in which it is found, and never
swims with the graceful, buOyant motion
Of other fishes, but changes its location by
i sudden darting motion. The whole
family to which it belongs are small fishes.
The late Prof. s S. Haldeman describes
two new species from the Susquehanna
belonging to an allied genius and the
lato Jacob Stauffer discovered third one
from the ConestOga, which was described
by Prof. Cope. Perhaps there were few
boys who had access to stream Of water
to whom this little fish was not familiar.
1t was quite abundant in Dr. RathvOn's
boyhood in the Susquehanna, aud he often
succeeded in angling for it with small
hook, but it was more frequently taken
with "dip net, and used as 4 bait for
larger fish.
A bottle of insects taken at, and i'll the
vicinity of York Furnace spring, during
the encampment of the Tucquau club, in
the present month, consisting mainly of
the general Cdlas0nla, Prionus OrthOsomd,
ChrysOcus, Languria, Tstraopes and Eriphus
The last named occurred in
tOierab' abundance" Oh the bloom Of a
species of Solidago, along the river from
York Furnace station to the mouth Of
Tucqaun. Four specimens Of' shell rock"
found on Bair's Island by Mr.. VIM. l..
Gill, differing very much from each
other. These were found III large water
worn pebbles, and must have been borne
down the stream from remote localities
above, as TO locality Of such i rock has
been discovered in Lancaster county. For
more than forty years, small bOulders aud
various sized pebbles have been found on
the beaches. bars and islands Of the Sus-
quehauna, but no locality has yet been
found where this rOck exists en- mass.
Some of these fossil remains" appear to
belong to the Radiates, some to the Ar-
ticul0tes, and others to the M0llusks, and
perhaps also to different geological periods.
