My DEAR sir: The accompanying manuscript is a treatise on the Calcites 
of New York which I have the honor to recommend for publication as a 
memoir of the State Museum. This work has been skilfully executed by 
Herbert RP Whitlock, Mimeralogist; and its excellence entitles it to 
publication. 
Very respectfully
