have been inflicted on the nomenclature of tin- science by ignorance 
and recklessness. In not a few cases they have corrected errors in 
spelling and formation by giving the proper term as Xenaspte, Hyopso- 
dontidce, Platycarus, Hoplosaurus, etc.. and they recommend the form 
Tin rumorpha instead of Tlxcromora. Other valuable suggestions in the 
same direction are also made, the adoption of which would much im- 
prove the literature of palaeontology without in most cases any counter- 
vailing disadvantage. 
Of the care and accuracy that mark the execution of the work it is 
impossible to speak too highly, Some evidence of them can be found 
in the fact that in a thorough examination for various purposes we have 
detected only a single misprint in all its 1,500 pages — Rhynchodes for 
Rhynchodus ( on page 052 ). This is, as might be expected, repeated in 
the index. 
We shall not, at present at least, follow our authors through the 
palseobotanical part of the work where we miss the master-hands so 
evident in the palseozodlogical. This part is confessedly only a compila- 
tion, but a good one, of our present knowlege of the subject. We leave 
them with a feeling of gratitude for the great work which they have 
acorn plished and with the hope that they will live to bring out another 
edition which the progress of their science will assuredly before long 
render necessary. 
CORRESPONDENCE. 
Db. Fuanklix C. Hill, Cubatob of The Geological Museum at 
Princeton College, for some years past, died in the early part of Novem- 
ber. Though not well known to the outside world. Dr. Hill was an 
enthusiastic worker in his department, and the museum in his charge 
will long be a witness to his skill in arranging, and his neatness and 
clearness in labeling his specimens. Some years ago Dr. Hill published 
a pamphlet illustrating the plan he had adopted of mounting every 
vertebrate bone so as to show its natural place in the skeleton. This 
system gives great additional value to the series of fossil Vertebrata at 
Princeton. 
Dr. Hill is also well known to entomologists for many valuable obser- 
vations and for a set of large drawings (since photographed and kept 
for sale) of the stag-beetle — Litcanm ccrvus, and the ground beetle— 
.Harpalus caUginosus, showing full details of their anatomy.
