BULLETIN OF THE LABORATORIES 
two bands of conglomerate, which include between them the middle 
member or Waverly proper. 
The upper Waverly, with its 100-150 feet, has been rather less 
studied than either of the other divisions. Near the top it is charac- 
terized by Prodiictiis semireticulaiiis, Spirifer stratiforinis ^ Phillipsia me- 
ramecensis, Nauiilus sp, Crenipecten^ sp. n. Hemipronites is also very 
abundant. 
The upper conglomerate, or congl. II. is itself often fossiliferous 
with the species characteristic of the shale below and especially Spir- 
fer winchelli. Allorisma winchelli, A. ventricosa^ Sanguinolites obliquus^ 
Prothyrus meeki, Edmondia, etc., are the determinative forms for the 
shale. The free-stone which lies below this shale is full of fossils. 
Spirife}' carteri, Crenipecten winchelli^ Phillipsia shamai'di^ Rhynchonella 
coope^i and R. contnicta are characteristic of this zone. After an in- 
terval of shale, sometimes with Allorisma winchelli, but generally bar- 
ren, we reach congl. II, which varies from a narrow belt of sandy free- 
stone to TO feet of coarse sand and conglomerate. A few feet below 
this is one of the most characteristic layers of the whole formation, 
abounding in Palceoneilo concentrica, and P. atteniiata, Sanguinolites 
imioniformis, Streblopteria media, Bellerophon lineatus, B. galericiilatiis, 
etc., etc. The same fauna may be found for 30 feet below, but 40-50 
feet below is a zone with quite a different habitus, containing Ryncho- 
iiella sappho, Leiopteria ortoni, Crenipecten tumidus. 
Near the same horizon, probably below it, but exposed further 
west and not yet certainly located vertically, is a zone with Spirifer 
marionensis, which species is also abundant in limestone nodules some 
15-20 feet lower along with a peculiar fauna of considerable individu- 
ality, at Moot’s run. 
Through the kindness of Mr. E. S. Clarke, a system of levels was 
run from Granville to exposures eastward from Newark, correcting the 
barometric work of last year. The conglomerate I. being the most 
available base line, the levels refer to the top of this stratum, which 
is exposed along “ the avenue ” leading to the buildings of Denison 
University. Along a line bearing S. 68° E., for 3 85 miles, this con- 
glomerate dips 79.35 feet, from this point to the south Newark quarry, 
a distance of 4.44 miles S. 79° E. the dip is 48.74 ft. A portion of 
the difference in inclination is due to the increased thickness of the 
conglomerate to the eastward, but the influence of the Clay Lick arch 
is also beginning to be felt. In our last report the mistake was made
