Moreover, the present author [hf] was lucky to obtain a photo copy of Messier's
personal copy of the catalog, including some of his personal notes on his
original observations and discoveries of nebulae and star clusters, which is
part of the Bibliotheque de Camille Flammarion.
Camille Flammarion was lucky to find this booklet at an antique book
store, see [a translation of] his report.
This copy was generously provided by Dr. Donald J. Greeley, who had
obtained it himself from Adoin Dollfus. It as served, and still serves,
as source for revisions and improvements of the translations, and as source for
further comments.
Some original translations from Messier's personal copies and observing notes

John Herschel's GC as GC 1594 and, consequently, into
Dreyer's NGC as NGC 2478, no cluster is found, so that this
object was missed, until
Oswald Thomas identified it correctly but perhaps by chance in 1934
as Herschel's cluster H VIII.38 (NGC 2422),

sign error in RA difference when reducing the positional data.)

`Note. The constellation of Virgo, & especially the northern Wing
is one of the constellations which encloses the most Nebulae: this Catalogue
contains thirteen which have been determined: viz. Nos. 49,
58, 59, 60,
61, 84, 85,
86, 87, 88,
89, 90, & 91.
All these nebulae appear to be without stars: one can see them only in a very
good sky, & near their meridian passage. Most of these nebulae have been
pointed to me by M. Méchain.'
(This notion is apparently the first impact of the
Virgo cluster of galaxies
into the scientific literature, i.e. the discovery of that galaxy cluster).

`Nebula, fine, distinct, & very bright, between the knee & the left leg
of Hercules, it can be seen very well in a telescope of one foot [FL].
It contains no star; the center is clear & brilliant, surrounded by
nebulosity & [it] resembles the nucleus of a large Comet: its brightness,
its size, approach much that of the nebula which is in the girdle of Hercules.
See No. 13 of this Catalogue: its position has
been determined, by direct comparison with the star Sigma Herculis, fourth
magnitude: the nebula & the star are on the same parallel.'

`Nebula without star, above the Heart of Charles [alpha Canum Venaticorum],
on the parallel of the star no. 8, of sixth magnitude of the Hunting
Dogs [Canes Venatici], according to Flamsteed: In the center it is brilliant
& the nebulosity [is] a bit diffuse. It resembles the nebula which is

(March 24, 1781)
`Nebula in the great Bear [Ursa Major], near Beta:
It is difficulat to see, reports M. Méchain, especially when one
illuminates the micrometer wires: its light is faint, without a star.
M. Méchain saw it the first time on Feb 16, 1781, & the position
is that given by him. Near this nebula he has seen another one, [the
position of] which has not yet been determined [M108],
and also a third which is near Gamma of the Great Bear
[M109 near Gamma Ursae Majoris].'

[M99], situated in the ear of Virgo. Seen by M.
Méchain on March 15, 1781. These three nebulae, nos. 98, 99 &
100, are very difficult to recognize, because of the faintness of their
light: one can observe them only in good weather, & near their passage
of the Meridian.'

it is very faint; near it is a star of the sixth magnitude.'
(Handwritten position added by Messier in his personal copy:
14h 40m, +56.)
(The discoverer, Pierre Méchain, disclaimed the discovery of
this object in his letter to Bernoulli, written May 6, 1783, and declared it
was an erroneous reobservation of M101. However, his description matches
well with an existing object, NGC 5866,
as does Messier's position measurement, if one takes an error of exactly
5 degrees in right ascension into account. This issue was ever since,
and is still, subject to
controversial discussion.
Anyway, M102 was missed for more than
a century.)

[A position follows which agrees with Herschel's H I.43, according to
Camille Flammarion, see below]
(Méchain in his letter to Bernoulli, May 6, 1783)
`On May 11, 1781, I discovered a nebula above Corvus which did not appear
to contain a single star. It emits a weak light and is difficult to find
if the micrometer wires are illuminated. This does not appear in the
Connaissance des Temps.'
(Flammarion:
`It has the position of the nebula H I.43 found by Wm. Herschel, and is No.
4594 of the NGC of Dreyer. We can add it to Messier's catalogue and give
it the number 104. The result is that Messier's catalogue from now on is
reckoned as numbering 104 instead of 103.')
