LETTER FROM THE AUTHOR.



AIr. John R. Procter,
             Director KenttckJty Oeoloqiral 8trveiq:
   DEAR SIR: As you know, several years lita't' liassed since I began the
work of describing and illustrating the fossil corals of Kentueky. The
delays incident to preparing such a work for the press, occupied as I aml
most of the time with engrossing public duties, have suggested that now,
since the plates and the explanations of the plates have been completed, it
is best to publish these as PART II., simply prefacing them with an alpha-
betical index.
   The text of Part I. will be finished in a few months. PART I. consists
of L An Introduction, which treats of the growth and habits of coral-
making animals, their place in nature, etc.; 2. A Descriptive Text,
which classifies the fossil corals found in the Silurian and Devonian Rocks
of Kentucky, showing the relations of families, genera, and species, and
describing them; 3. A chapter of Popular Notes, which, following the
technical descriptions, presents the salient traits of structure or function
characterizing the skeletons of species of the same genus, on the modifica-
tions of which the differentiation is based, and collates comprehensively
the vsemblances and differences of related genera and the more widely
divergent family peculiarities; 4. A Glossary, in which are given the
meanings and, in most cases, the etymologies of the technical terms used
in the text; 5. An Index, systematically arranged.
  The literature of this subject is diffused through many volumes of State
and Government reports and society periodical or casual publications.
Many zealous students of paleontology, confused by synonymy or per-

 





plexed by descriptions and figures of badly-preserved fossils, have aban-
doned research among these interesting and beautiful forms for the easier
study of mollusks, crinoids, worms, or crustaceans. May I express the
hope that the present work will prove a useful manual to the student
   As will be seen, the number of plates is one hundred and thirty-nine,
the number of specimens figured about one thousand. The number of
species described is more than three hundred; of these about one hundred
and seventy arc new arid heretofore undeseribed. The beautiful condition
in which these fossils occur in Kentucky and the care with which they
have been freed from their matrix have permitted a satisfactory photo-
graphic delineation by the "artotype" process.  Mr. E. Klauber, of
Louisville, has done this part of the work under my supervision in the
most artistic style. My thanks are due to this gentleman for the assist-
ance he rendered me in " setting up" the fossils before the camera, and for
his amiable co-operation during the several years we have been engaged
together in plate-making.
   Permit me also to thank you, sir, the Director of the Survey, and the
other officers of the State of Kentucky, whose generous consideration has
given me the opportunity to publish this contribution to the geology of the
country in so handsome a volume.
                 Very respectfully, your obedient servant,
                                                WILLIAM J. DAVIS.
  LOUISVILLE, 1885.
