44. Natural History._-M. Drapier, Professor of Chemistry 
and Natural History, and one. of the editors of the “« Annales 
generales des sciences physiques,” has substituted with suc- 
cess, in lieu of the poisonous matters employed in preserv- 
ing objects of natural history, a soap composed of potash 
and fish oil... He dissolves one. part of caustic potash in 
water, -and.adds to the solution one part of fish oil: herubs 
the mixture till it acquiresa pretty firm consistence. When 
it 1s completely dry he reduces it to. powder, with a rasp. 
One part of this powder is employed in forming a soft paste 
or liquid soap, by means of an equal quantity of a solution 
of camphor in musked alcohol... This liquid soap is well 
rubbed upon the skin of the bird, previously cleared of its 
fat, and the other part of the soap and powder is plentifully 
scattered between the feathers. ‘Thus prepared, the bird:is 
placed in a moist situation in order that the particles of soap: 
may soften and attach themselves perfectly to the feathers, 
the down and the skin. It afterwards is put in a dry place. 
By this means it completely resists the attacks of larve, ‘and 
has neither the danger nor the. inconvenience of arsenical 
preparations, which, as is well known, stain and spoil aary 
extremities of the feathers and down. 
45. Anatomical model, representing par beets the my- 
ology of the human body. —M. Ameline, Professor of As- 
tronomy of the School of Caen, has just invented, and com=: 
posed an anatomical model of a human body, of the natural ; 
size. This modelis formed, 1st, of real bones, which con-: 
stitute the skeleton. . 2d, of muscles made of pasteboard,: 
which after being softened and fashioned true; to nature, are) 
covered with fine blades of hemp, so as to imitate the mus- 
cular fibres, and afterwards painted of a natural colour... 3d, 
of threads and cords of cat-gut, covered with coloured var- 
nish, so as to resemble arteries, veins, and nerves. 4th, of 
real hair on those parts to which it belongs. By means of 
this exact image of the structure and colour of the organs 
which compose the human body, students may examine 
with facility parts which itis very difficult to observe accu- 
rately in a dead subject. This model presents the parts un- 
der their various aspects, admits of their being handled, de- 
tached and separately studied without altering their natural 
forms. It serves too for demonstration when the heat
