several pieces of the skull, long bones, etc., etc. The larger piece 
was from the base of the left tusk, two feet in length, and flat- 
tened on the inner side, evidently produced by the friction of his 
trunk. This specimen retains the fine polish as perfectly as when 
worn by the living animal. This interesting specimen I recently 
presented to the Academy of Science of Chicago. 
Dr. Koch’s report, in the ‘* Proceedings of the St. Louis Academy 
of Science,” is unreliable in every particular, saving the locality. 
The Doctor certainly exercised a lively imagination when he stated 
that “the bones were found in a layer of vegetable mould which 
was covered by twenty feet in thickness of alternate layers of 
- sand, clay, and gravel,” and that under this extensive stratifi- 
cation he found the identical flint arrowhead that the Mound 
builders used in slaying this giant of past ages, taking advantage 
of his helplessness, being mired hopelessly ! ! ! 
This skeleton was discovered by a man who scooped out a hole 
_ in the “lick” for the purpose of obtaining drinking water. He 
struck upon the scapula at a depth of two feet. This discovery 
was reported to-Dr. Koch, at Warsaw, and he visited the locality 
and secured the prize. 
I am pained to record this evidence of Dr. Koch’s want of accu- 
racy in this matter, but the cause of science seems to demand the 
truth. Dr. Koch’s report has been quoted in proof of the antiq- 
uity of man. The position and state of the bones rather go to 
show that the Mastodon lived in an age not so remote as usually 
supposed. I should not be surprised if the evidence were speedily 
found to prove that man was contemporaneous with the Mastodon, 
but, certainly, the Missourium affords none.

Oner of the most curious habits of spiders is that of flying, 33 
it is often called. This has no resemblance to the flight of birds 
or butterflies, for spiders have no wings nor any organs which 
could answer the purpose of wings. ‘Their ability to rise in the
