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: he rubs 
mixture till it acquiresa pretty firm consistence. When 
it is completely dry he reduces it to powder, with a rasp. 
e 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 arsenic

45. Anatomical model, representing particularly the: 
ology of the human body.—M. Ameline, er 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 model is formed, Ist, of real bones, which con- 
stitute the skeleton. 2d, of muscles made of pasteboa 
which after being softened and fashioned true to nature, are 
tached and separately studied without altering their natural 
forms. It serves too for demonstration when the hea
