were first made known by Ebenezer Emmons. He described 
their stratigrapical and mineral characters as carefully and fully 
as any one was capable of doing in his day, and he furnished 
the palaeontological evidence by which they might be determined, 
and gave to them a geographical name according to the require- 
ments of nomenclature. Every species illustrated by him is 
a valid species to-day, and none of them occur in higher rocks. 
The generic name Ellipsocephalus was preoccupied and hence 
gave way to the later name Olenellus^ but Olenelllis asaphoides 
is characteristic of the Upper Taconic in the region explored 
by Emmons, and the genus is characteristic elsewhere. His 
Atops trilineatus is characteristic, though complaint has been 
entered against the name Atops because he did not define it, and 
some use therefore the later generic name Ptychoparia. He 
illustrated, and named the fossil for the purpose of showing the 
fauna of the rocks, and whether his generic name shall stand or 
that of Corda be substituted, is of no importance, so far as his 
labors went, in establishing the Taconic system. 
EDITORIAL COMMENT. 
THE RIGHTS OF INTELLIGENCE UNDER PAID SERVICE. 
Again we hear the sound of complaint in behalf of uncredited 
and unhonored work performed under contract, for a pecuniary 
consideration. It is a familiar sound. A bright and industrious 
young man enters into an agreement with an employer to per- 
form a certain service involving more or less learning, intel- 
ligence and administrative ability. It may embrace work in 
original scientific investigation. The engagement runs on for 
years by mutual consent, and the employed acquires a high de- 
gree of ability for original research. The results of his labors, 
however, appear under the name of his employer; and the im- 
mediate investigator's name remains unannounced to the public 
— at least, uncredited for the work done. Such instances have 
fallen under our observation from the fields of general geology, 
palaeontology, zoology and botany; and the paid investigator
