BULL. GEOL. SOC. AM., VOL. 2. 



Irregular Publications. 



In the interests of exact bibliography, the Society takes cognizance of all publica- 

 tions issued either wholly or partly under its auspices. Each author of a memoir 

 receives 30 copies, and is authorized to order any additional number at a slight 

 advance on cost of paper and presswork ; and these separate brochures are identical 

 with those of the editions issued and distributed by the Society. Contributors to the 

 proceedings also are authorized to order any number of separate copies at a slight 

 advance on cost of paper and presswork ; but these separates are bibliographically 

 distinct from the brochures issued by the Society. 



The following separates of parts of Volume 2 have been issued : 



Editions uniform with the Brochures of the Bulletin.
