CHINESE MAGNETIC CHARIOT. O 



commanclcrs and officers of ships sailing to foreign ports. But it is not 

 foreign products that are most desirable — our own natural histoiy espe- 

 cially should be cultivated by us — our own quadrupeds, birds, reptiles, 

 fishes, insects, shells, &.C., &c., should be collected with zeal and ma- 

 turely studied. 



I hope that the interest awakened in this pursuit in Pennsylvania 

 College will not speedily languish. A respectable beginning in the for- 

 mation of a cabinet has been made and large and valuable additions may 

 shortly be expected. The establishment of the Li.vnjean Society au- 

 gurs well for the promotion of natural history in the College, It is the 

 first association of the kind ever established in any college in this coun- 

 try which undertook to publish a Journal of Natural History. It is a 

 most commendable enterprise and reflects unspeakable credit on the 

 young gentlemen themselves and the institution with which they are 

 connected. 



It is hoped the members will continue to be industrious in the col- 

 lection of objects among tneir friends at home, and lay every person 

 under contribution who has any thing curious in nature or art. 



It would be an interesting and useful pursuit for the membei-s to col- 

 lect all the objects of natural history afforded by Adams County, or as 

 naturalists call it, to collect a Fauna of that geographical section. This 

 could be done with a little perseverance and it would be a most healthy 

 employment. Some of the znembers are already not unskilled in taxi- 

 dermy, and others 1 happen to know, are dexterous in capturing zoolo- 

 gical prey. Let the shells and fishes of Marsh Creek and the mountain 

 streams be collected before winter — let the reptiles be taken before they 

 enter on their hybernating torpor — let the insects be captured before 

 they perish or seek their retreats from the cold — let the birds be shot 

 before they all migrate to more genial climes — let the quadrupeds be 

 caught at all seasons — and in a sliort time an interesting collection of 

 Che Natural History of Adams will have been secured. When it is once 

 known that such an enterprise is in progress, many objects will be sent 

 to the Association by gentlemen in the country, or by amateur .sportsmen, 

 who will take pleasure in contributing to the rabhiet. J. G. M.

The directive property of the magnet was first noticed in a mineral 

 substance called the va/ivc magnri or the loadslonc^ which is an ore of 

 iron consisting chielly of the two oxides of that mclul, together with a
