position of the bird in the. embalmed specimens is found to be 
invariably the same. The neck and head: are drawn down be- 
tween the legs, the lower mandible being presented outward and 
downward, and the legs drawn forward beneath the body. of the 
_ bird, as if in asitting posture, with the wings folded over the oe 
“neck and legs. Some specimens less perfectly bandaged seem 7 
have undergone a process of carbonization, and on the removal = 
of the linen folds crumble into a dark powder, in which the bones 
appear, though reduced to a brittle state. 7 
Dr. Morton. referred to the very recent appearance of the pot 
tery ware in which these specimens were contained ; notwith- 
standing their extremely ancient date, which is at least three 
thousand to four thousand years. -The pyramids of Sakhara are 
among the most ancient monuments of human art. ‘These cases 
containing the embalmed. ibis are still found in great numbers, 
though the traveller, Dr. Pococke, gave his opinion one hundred 
years ago, that they would probably soon become extinct. 
Dr. Morton then proceeded to open another envelope contall- 
ing some unknown embalmed object, which he conjectured to be 
a mass of snakes or serpents. ‘This was less carefully enclosed 
than the ibis, being coarsely enveloped in-rags rather than ban- 
dages, though still covered by hundreds of folds of linen. 'Thes?. 
being at length removed, disclosed the wing of a bat! 
The next embalmed. object unfolded was a young crocodile, 
(Crocodilus niloticus,) about a foot in length, and in good preset” 
vation. Dr. M. observed that this animal is found in embalme 
specimens of all sizes, from the apparently just hatched young a 
those of five feet in length, one of the latter size being at present 
in his collection. . 
Mr. Quinby exhibited specimens of silver, lead, and other ors 
from the Andes in Peru, accompanying them with some obsetv® 
tions upon their product, situation, &c. 
Prof. Johnson showed specimens of magnetic iron ore from em 
_ State of New York, which he had found to contain titanic acl, 
combined with iron and manganese. 
» Dr. Locke made some observations on the application of mag- 
netism to the discovery of metallic veins and deposits.
