IN a recent publication Dr. ArrHur Ho.ttck? has described 
the discovery of amber in the Raritan formation of the Middle 
Cretaceous, at Kreischerville, Staten Island. The amber in ques- 
tion occurs in largest quantity “in a stratum or bed, characterized 
by layers and closely packed masses of vegetable débris, consisting 
of leaves, twigs, and fragments of lignite and charred wood.” Lig- 
nite occurring in association with amber at Cape Sable, Magothy 
River, Anne Arundel County, Maryland, collected by Professor 
A. Brpsrns of the Woman’s College, Baltimore, and of somewhat 
similar geological horizon, has recently been determined by Dr. F. 
- Kyowrron? of the United States Geological Survey as a new 
species of Cupressinoxylon. It appeared desirable to one of us 
that the lignites associated with the Kreischerville deposits of amber 
should be subjected to microscopic examination, in view of the 
possibility that the succiniferous ones might also turn out to belong 
to an extinct species of Sequoia (Cupressinoxylon). On communi- 
cating with Dr. Hotticx in regard to this possibility, he very kindly 
consented to a combined visit to the beds at Kreischerville, for the 
purpose of securing authentic specimens of the succiniferous and 
other lignites. On April 18, 1905, we examined together the various
