308 GEOLOGY OF ANTIGONISH COUNTY —HONEYMAN. 
Art. XI.—A REVISION OF THE GEOLOGY OF ANTIGONISH 
County, IN Nova Scotra.—By Rev. D. HoNneEy- 
MAN, D.C. L, F.RS. C., F.S.Sc., Hon. Member’ 
of the Geologist’s Association, London, é&e. 
(Read May 10, 1886.) 
THE construction of a line of railway, which passes through 
this County, has exposed interesting series of rocks which were 
largely obscure. Geological investigations of cognate series in 
other parts of the Province have, in turn, cleared up certain 
doubts in reference to series in the County which are regarded 
as “Typical.” The examination of correlated series elsewhere 
have contributed somewhat in this direction. The application 
of the microscope and polariscope to the study of the crystalline 
rocks, besides revealing the character and constitution of the 
rocks themselves, seem also to indicate relationship and age, 
and thereby serve, in a manner, to determine the relationship 
of associated non-crystalline rocks. In some cases, too, compara- 
tive paleontology, without lithology, lends its aid in confirma- 
tion of certain conclusions. These considerations have induced 
me to make a revision of the Geology of Antigonish County. 
In no other County has the geology been so fully investigated. 
Parts, however, yet remains to be examined. I have aeoneee 
in this field as an amateur or Provincial geologist, more or less, 
during a quarter of a century, and yet corners remain un- 
touched.
