There are, moreover, some other objects which, according to their place in the region, 
occupied by N. G. C. 628, are dubious as to their Globular-Cluster-nature, viz., — 
G.C. 68 described as Globular Cluster, vF, cC

These objets, which probably are spiral nebule of the same general character as 
G.C. 372, are excluded from the representation of the Globular Clusters in Plate 1 
and marked separately on the second figure of the Plate, which contains all objects 
excluded. 
These few discordances of the descriptions of the N.G.C. from more recent 
observations are sufficient to point out that a probably considerable number of 
objects, designed in the catalogue as Globular Clusters, may refer to spiral nebul&e of 
the known form exhibited by N.G.C. 628. The difficulty in all cases clearly to 
distinguish the Globular Clusters from other objects expresses itself even by the 
Herschelian distinctions: 
r mottled. not resolved: 
rr partially resolved, some stars seen: 
rrr well resolved: clearly consisting of stars. 
Consequently, the two first classes of objects were omitted in the present research, 
and thus the reproduction in Plate 1 does not contain other objects than those which 
in the catalogue either are designed as rrr or in respect to which the magnitudes 
of the stars involved are expressely indicated as st 11, st 14—16 and so on. The 
objects, thus regarded as doubtful, are represented in the additional charts. It is 
to be seen that most of the Globular Clusters, contained according to the catalogue 
in the two Maghellanic Clouds, belong to this category. In fact, according to HER- 
SCHEL'S classification, there are in the Nubecula minor 3 Globular Clusters, two of 
which are uncertain, and in the Nubecula major 5 Globular Clusters, 3 of which are
