[Nov. 7, 
The adversaries of the Taconic system have constantly placed 
their theories first, and facts have been explained by suppositions, 
or guesses and arbitrary use of palaeontology and dynamic strati- 
graphy, never losing sight for a moment of mathematical rules, es- 
tablished according to their views without a possible doubt. They 
have applied carelessly and inexactly all their empirical palaeonto- 
logical laws, without any regard whatever to the actual state of 
things on the ground putting entirely aside stratigraphy and lithol- 
ogy. But even, when their own rules of palaeontology to deter- 
mine the age of strata are against them, they have not hesitated 
to make either erroneous identifications of species, or transfer an 
entire zone of primordial fauna, in order to suppress the whole or 
at least a good portion of the Taconic. 
As to stratigraphy and lithology the adversaries of the Taconic 
have constantly erred ; and we have the rare and singular specta- 
cle of observers claiming to know only stratigraphy and lithology, 
making classifications entirely in opposition to all the principles of 
those two branches of geology, submitting very tamely, all their 
views and conclusions to the decision and advice of palaeontologists, 
and of palaeontologists all of whom are opposed to Barrande’s doc- 
trine of colonies. They seem to have closed their eyes to the 
facts, and endorsed by the majority they are satisfied. Such a 
spirit is contrary to modern science, and recalls the orthodox and 
official science of the middle ages at the time of the adversaries 
of Galileo. 
CONCLUSIONS. 
As a conclusion, we can say that the geological survey of Canada, 
from its beginning until the present time, has been a constant, and 
unfair, adversary of the Taconic, for it has never used nor ever men- 
tioned anywhere in its official reports and publications the re- 
searches, discoveries and classifications of Dr. Emmons and Marcou. 
The right of priority has been entirely set aside. Not being suc- 
cessful in their undertaking of giving local names, which were never 
accepted to any extent by geologists at large, the Canadian geolo- 
gists have lately substituted for their Quebec, Acadian, Anticosti, 
Guelph and Gaspe formations and groups, the English nomencla- 
ture of Cambrian, Cainbro-Silurian, Siluro-Cambrian, and Silurian. 
It is true that at the beginning of the survey, Logan tried to fol- 
low the classification and a part of the nomenclature of the state
