the quartzite stratum has little persistence in any direction. 
Its representative in this region, when absent, is mica slate. 
VIL. Only 800 feet of the Monument Mountain formation 
are folded up in each of the folds V? and V° in the section 
represented in fig. 5. is was probably because these folds 
are so small, the overlying beds having been rejected, broken 
up, and carried off. T'wo synclinals and an anticlinal are com- 
prised within a breadth of only two-thirds of a mile. 
IIL. Steep synclinals of slate, when the slate is associated 
with a thick stratum of limestone and is the overlying rock, 
should make ridges; and per contra, steep anticlinals if the slate 
1s the underlying rock. In both cases, to produce an enduring 
ridge, the slate should be folded on itself so as to make a com- 
mon mass; and this is not the case in an anticlinal with lime- 
_ two more sections across this western part of the Great Bar- 
Tington region remain to be described.

27th, from their numbers, and from their probable connection 
with Biela’s comet, are of such interest and importance as to 
Justify a minute record of observations upon them.

1. In New Haven.—On the evening of Sunday, Nov. 24th, 
about 7h 85", Arthur T. Hadley, a student in Yale College, saw 
several meteors descend from the constellation Cygnus toward 
the western horizon. He called the attention of his uncle,
