The monthly evening meeting of the Society was held on Tuesday, the
15th November, His Excellency Sir John Henry Lefroy, K.C.M.G., the
President, in the chair.
Specimen presented to the Society from Mr R.M Johnston,of a species of Sea
Bream (Girella tricuspidata), from Southport. In reference to this
specimen, Mr. Johnston remarks :—"This interesting fish was
obtained by me from a dealer, and is locally known to the boatmen
as 'The Sweep.' Hitherto this species was either not known
to exist in Tasmania, or it may have been confounded with some
other member of the 'Sea Bream' family.
The President exhibited a number of harmonic curves drawn by
Donkin's Harmonograph. This instrument is described in the Proceedings
of the Royal Society for 1874. The mechanical construction of it is such that a finely pointed glass pen, following the motions of a
pendulum, or of a regularly oscillating crank, traces an endless line on
a sheet of paper which is itself in motion under the influence of another
crank or pendulum. Some of the curves were produced with pendulums,
and some by wheel-work.
A botanical paper, by Baron F. von Mueller, K.M.G., M.D., F.R.S.,
entitled "Notes on Leontopodium catipes," was read by the Secretary.
