Professor Bucklancfs Instructions, ^c. 251 



a list of the number and thickness of each of the beds of 

 coal and their supposed extent, stating whether limestone 

 or iron ore, or springs of bitumen occur near them. 



Fossil plants, corals, shells, fish, and bones of all kinds, 

 with a portion of the rock in which they are found, are of 

 all specimens the most valuable. Also fossil tusks and teeth 

 and horns of elephant, rhinoceros, hippopotamus, ox, stag, 

 &c. &;c. which abound in diluvian gravel over Europe, 

 North America, and Siberia. 



If there be any example of petrified human bones, spe- 

 cimens of them, accompanied by portions of the substan- 

 ces in which they occur, and a minute description of their 

 situation and circumstances, are particularly requested : they 

 should be sought in beds of diluvian gravel, which are 

 spread abundantly over the surface of all great vallies in the 

 world. 



Rules for selecting and conveying specimens. 



In selecting specimens of common rocks, the best size is 

 that of a common flat piece of Windsor soap, taking not the 

 outside bit, but the second slice that is struck from the block 

 by the hammer. 



Every specimen should be ticketed with the name of the 

 place where it is found, or with a letter or number referring 

 to a catalogue describing it: in case of places little known, 

 their distance from the nearest important town, and in what 

 direction should be specified. 



Every specimen should be wrapped in a separate piece 

 of paper, and the whole closely packed with moss or hay, 

 in a barrel or strong box, to be sent by ship to London, di- 

 rected to " Rev. Professor Buckland, Museum, Oxford, to 

 the care of Mr. Hunneman, 5 Mead-street, Dean-street, 

 Soho, London." The bill of lading, with notice of the 

 arrival of the vessel, should be sent to Mr. Hunneman, who 

 is Mr. Buckland's agent, and will duly forward the package 

 to Oxford. 



It is desirable to get sent to England a list of the best maps and books de- 

 scriptive of foreign countries, specifying how far they are correct, and their 

 time and place of publication ; and also a list of the names and address of 

 all the naturalists that may be resident in them, stating to what department 

 of natural history they have given most attention, and whether they would 

 be willing to correspond with persons in England who are devoted to the 

 same pursuit.
