LVote on Mr. Kiimmel’s Review of the ‘‘ Reconstruction of the Antillean 
Continent.” 
Mr. KUMMEL’s review of the paper under the above title is of par- 
ticular interest in calling attention to impressions which topics not 
considered by the author produce upon a conservative reviewer, some- 
what hesitating in accepting the recently set-forth theory of great 
continental elevations, although willing to admit an equal amount of 
terrestrial movement, providing much of it be confined to the sinking 
of the floor of the sea. ‘The startling character of the changes of level 
in late times has impressed itself upon none more than the author, for 
it took several years to overcome the prejudice against an apparent 
hypothesis which had not commonly entered into our literature. The 
papers so far published are only part of those ready, or in preparation,

than had been anticipated. These results will be offered in course of 
time to the public; but even with these published, the work must not be 
considered as scarcely more than commenced, for it is impossible to 
predict to what limits it will reach. s 
Mr. Kiimmel says that the author makes no reference to sunken 
delta deposits, and therefore infers that they do not exist. Not at all. 
It is one of the several topics which along with the more important 
questions of the slopes of the drowned valleys, has not been discussed, 
and which the reviewer deprecates as not having been considered,—a 
point well taken. The slope of the sunken valleys ought not to be 
compared with those of the eastern part of the continent, but with 
those on the margins of the Mexican table lands and other regions 
within the tropics, while the declivities of the continental valleys of the
