“The term ‘type,’ as employed in the Geological Depart- 
ment of the American Museum, embraces not only the speci- 
mens actually used by an author in the original description of 
a species, but also those specimens which have been used by 
the same author in the further elucidation of the species in 
subsequent publications. The types may or not have been il- 
lustrated in connection with the first publication. ‘Figured 
specimen’ is the term applied here to the specimens which 
have been identified with a species by another person than the 
author of the species and which have been illustrated in some 
publication. From the standpoint of the student aad investi- 
gator, types are the most valuable portion of any collection, 
and should, therefore, be marked in some conspicuous manner 
and be preserved with the greatest care. All the types and 
figured specimens in this department are individualized by the 
use of a small rhomb of emerald green paper securely gummed 
to each.” 
ScuureEr, IN ADVOCATING AN AQuEo-IGNEOUS THEORY of 
the origin of granite, suggested that, owing to the presence of 
water the magma might cool down considerably below the tem- 
perature necessary for solidification under the conditions of 
ordinary dry fusion, and thus allow minerals which cannot en- 
dure a high degree of heat to crystallize out before other con- 
stituents less fusible by the simple dry method.
