NOTE. 



The Curator of the State Collection -will gladly receive for it specimens of rare, or espe- 

 cially of new fossils. 



The attention of collectors is especially directed to the remains of Crinoids, Star-fishes and 

 Echini, which exist through nearly the whole series of rocks of New-York, but are hitherto 

 very rare; and any distinct relics of Fossil Fishes, such as scales, plates, bones or teeth, 

 will be very welcome. Good specimens of the Trilobites and other Crustaceans are also 

 desired, and shells of the larger and rarer forms. 



The more perfect specimens of such relics come under the eyes of observing persons only 

 occasionally, when favorable opportunities, such as excavations or quarrying operations, 

 offer; and cannot be collected at once by any amount of labor or exploration. To make the 

 State Geological Museum as complete and useful as possible, the Regents rely confidently on 

 contributions from students and friends of natural science, to whose aid they already owe 

 much of the most valuable part of the collection. 



It should be remembered that the useful value of any such specimen depends almost 

 entirely on accurate knowledge of its locality; that is, the particular formation, and, if pos- 

 sible, the stratum from which it came ; for, as has been before shown, it is on the presence of 

 certain fossil remains in certain formations that the whole historical conclusions of Geology 

 are founded. Care should always be taken that the correct origin of every fossil from its 

 rock be accurately known, and that it be not attributed to any other position than its true 

 one; otherwise it becomes a cause of error, instead of evidence of truth.
