PREFACE.
The investigation involved in this memoir is an extension of the
stellar catalogue presented in Publication No. i of the Vassar College
Observatory. Publication No. i gives a catalogue of stars within
one degree of the north pole. Publication No. 2 extends the cata-
logue to two degrees from the pole. Both catalogues are based upon
photographs taken by Professor Donner of Helsingfors, Finland,
and secured through the courtesy of Professor Jacoby of Columbia
University. The direction of the measuring and reduction of the
plates has been in the hands of Caroline E. Furness, Ph. D., assist-
ant in the observatory. The observations for magnitude, photo-
graphic and visual, made after the manner described in the text,
were carried on by the director. The computing corps has consisted
mainly of graduates of Vassar College, of whom Miss M. E. Tarbox
and Miss B. Tompkins have rendered especial service.
The major part of the expense of the reduction has been met by a
grant from the Carnegie Institution of Washington, D. C.

CATALOGUE OF STARS WITHIN TWO DEGREES
OF THE NORTH POLE.
i.
INTRODUCTORY.
The first publication of the Vassar College Observatory treats of
the measurement and reduction of a set of :f our, photographic plates
covering the region of the sky within one degree of the north pole.
These photographs were taken at the HekingfbVs Obse^atOry, Fin-
land, and form part of a series of twelve 'negatives, which together
include all the stars of less than two degrees polar distance. The four
plates first treated have their centers at declination 90, the remain-
ing eight have their centers lying on the circle of 89 declination at
intervals of 45 right ascension. Because of the high declination this
procedure results in a peculiar kind of overlapping, the character of
which can easily be seen by referring to Publication i, Sec. I, in which
is given a description of the plates and also an illustrative figure. The
present paper treats first of the measurement and reduction of the 89
plates with a preliminary catalogue of the stars found thereon ; sec-
ond, of the inter-adjustment of the several plates and their combina-
tion with the former catalogue, a problem which presents considerable
interest on account of the peculiarity of the overlapping above re-
ferred to ; and third, of the formation of the final catalogue of all the
stars found on the twelve plates.
The method of performing the measurement and reduction, which
form the first part of this paper, is in general the same as that em-
ployed in Publication i, Sees. II-VIII. Deviations from it are occa-
sionally necessary because of the fact that the north pole is no longer
at the center of each plate but is on the edge. These variations will
be mentioned in their appropriate places. A detailed description of
the plates is given in Publication i, Sec. I.
The meteorological and other data connected with the exposure
of the plates were sent from the Helsingfors observatory, and are
found in the accompanying table.

MEASUREMENT AND REDUCTION; PRELIMINARY CATALOGUE.
After some trial it seemed advisable to use both vertical and horizontal
threads in measuring the rectangular coordinates of the star images. Thus
both the X and Y coordinates were determined in the same position of the
plate. It was also decided to set upon both corners of the reseau square at
once, thus reducing greatly the number of micrometer readings. It was not
possible to set upon the lines as is customary, since for the most part they
were too indistinct. Otherwise the method of measuring and recording is the
same as that described in Publication i, Sec. II and III. Six plates were
measured by Dr. Furness and two by Miss BHse Whitney. The coordinates
of the standard stars were measured by both observers. Corrections were
made for errors of the screw, for the reseau and for error of runs. Table II
which follows contains the corrected coordinates of the two sets of images
measured on each 89 plate. It also contains the coordinates of certain
stars on the 90 plates which have a polar distance greater than i and hence
are not included in the catalogue of sixty-five stars found in Publication i .

PREFACE.
The investigation involved in this memoir is an extension of the
stellar catalogue presented in Publication No. i of the Vassar College
Observatory. Publication No. i gives a catalogue of stars within
one degree of the north pole. Publication No. 2 extends the cata-
logue to two degrees from the pole. Both catalogues are based upon
photographs taken by Professor Donner of Helsingfors, Finland,
and secured through the courtesy of Professor Jacoby of Columbia
University. The direction of the measuring and reduction of the
plates has been in the hands of Caroline E. Furness, Ph. D., assist-
ant in the observatory. The observations for magnitude, photo-
graphic and visual, made after the manner described in the text,
were carried on by the director. The computing corps has consisted
mainly of graduates of Vassar College, of whom Miss M. E. Tarbox
and Miss B. Tompkins have rendered especial service.
The major part of the expense of the reduction has been met by a
grant from the Carnegie Institution of Washington, D. C.

CATALOGUE OF STARS WITHIN TWO DEGREES
OF THE NORTH POLE.
i.
INTRODUCTORY.
The first publication of the Vassar College Observatory treats of
the measurement and reduction of a set of :f our, photographic plates
covering the region of the sky within one degree of the north pole.
These photographs were taken at the HekingfbVs Obse^atOry, Fin-
land, and form part of a series of twelve 'negatives, which together
include all the stars of less than two degrees polar distance. The four
plates first treated have their centers at declination 90, the remain-
ing eight have their centers lying on the circle of 89 declination at
intervals of 45 right ascension. Because of the high declination this
procedure results in a peculiar kind of overlapping, the character of
which can easily be seen by referring to Publication i, Sec. I, in which
is given a description of the plates and also an illustrative figure. The
present paper treats first of the measurement and reduction of the 89
plates with a preliminary catalogue of the stars found thereon ; sec-
ond, of the inter-adjustment of the several plates and their combina-
tion with the former catalogue, a problem which presents considerable
interest on account of the peculiarity of the overlapping above re-
ferred to ; and third, of the formation of the final catalogue of all the
stars found on the twelve plates.
The method of performing the measurement and reduction, which
form the first part of this paper, is in general the same as that em-
ployed in Publication i, Sees. II-VIII. Deviations from it are occa-
sionally necessary because of the fact that the north pole is no longer
at the center of each plate but is on the edge. These variations will
be mentioned in their appropriate places. A detailed description of
the plates is given in Publication i, Sec. I.
The meteorological and other data connected with the exposure
of the plates were sent from the Helsingfors observatory, and are
found in the accompanying table.

MEASUREMENT AND REDUCTION; PRELIMINARY CATALOGUE.
After some trial it seemed advisable to use both vertical and horizontal
threads in measuring the rectangular coordinates of the star images. Thus
both the X and Y coordinates were determined in the same position of the
plate. It was also decided to set upon both corners of the reseau square at
once, thus reducing greatly the number of micrometer readings. It was not
possible to set upon the lines as is customary, since for the most part they
were too indistinct. Otherwise the method of measuring and recording is the
same as that described in Publication i, Sec. II and III. Six plates were
measured by Dr. Furness and two by Miss BHse Whitney. The coordinates
of the standard stars were measured by both observers. Corrections were
made for errors of the screw, for the reseau and for error of runs. Table II
which follows contains the corrected coordinates of the two sets of images
measured on each 89 plate. It also contains the coordinates of certain
stars on the 90 plates which have a polar distance greater than i and hence
are not included in the catalogue of sixty-five stars found in Publication i .
