PERSONAL AND SCIENTIFIC NEWS. 
Prof. J. S. Newberry at the time of his death left several 
unfinished manuscripts. Among these was one for a mono- 
graph of the United States Geological Survey, entitled "The 
later extinct floras of North America." It deals with the 
fossil plants of the Cretaceous and Tertiary of the west. 
The entire edition of plates was published several years ago, 
but the descriptive part was in a very incomplete and frag- 
mentar)' state at the time of Prof. Newberr\''s death. Dr. 
Arthur Hollick has taken the manuscript and plates in hand, 
has hunted out the type specimens and has revised and com- 
pleted the descriptions. This volume is expected to appear 
shortly. 
Arkansas Geological Reports. The last legislature 
of the state of Arkansas provided for the printing of the 
hitherto uupublished reports of J. C. Branner, formerly state 
geologist of that state. There are five volumes of these 
reports, viz : (i) Coal ; (2) Lower Coal Measures ; (3) Clays.
