schemes to be of this type in which tlu- sum of all anatomical 
characters rather than variations in one lie at the base ; the two 
just referred to and Hyatt's classification of the cephalopods. 
Beecher's schemes are less oliscured with detail and an?lysis of 
phylogenetic status and hence '.nore adaptive to practic.l appli- 
cation. Hyatt evinces at every sta^^e the analytical ,:^rasp of 
the growth phase and its rapid utilization in classificat'on re- 
sulting in a much more complicated and detaded, if less readily 
applicable scheme. The latter in creating an army of new 
taxonomic values and names has at the same time created the 
necessity for as many more for phases of like value still un- 
expressed ; the former has built without such close analysis and 
his temis suffice. Hyatt's classification it seems to us will stand 
less well the test of time than those of his disciple, but Hyatt's 
powers of analysis and correlation ^in this line of biogeny are 
still unparalleled. Out of Bescher's study of the ontogtny of 
fossil brachiopods and trilobites came his noteworthy treatise 
on the Origin and Significance of Spines, in which the fact, 
recognized though not emphasized before, that the development 
of spines is an indication of the decline in racial vitality which 
precedes extinction, is set forth with a wealth of demonstration. 
The papers we have mentioned wall be regarded as the 
broadest in scope of professor Beecher's undertakings, but they 
are not of more permanent value than many of his less pre- 
tentious publications . 
As a teacher of his science Dr. Beecher had won an en- 
viable success. His courses were attended with zeal and in- 
terest and among his graduate students are some whosf^ work 
in his own department of the ?cience has reflected much credit 
on him and on themselves. He had also received substantial 
recognition of his achievements in the honors which huC come 
to him. The position he occupied in Yale as Universitv Pro- 
fessor of Paleontolog}', Professor of Historical Geology in the 
Sheffield Scientific School and Curator of the geological col- 
lections in the Peabody Museum was his most signal distinc- 
tion . He was also a member of the National Academy of Sci- 
ences. Foreign Correspondent of the Geological Society of 
London, etc. For two years he was President of th^ Con- 
necticut Academy of Sciences. The record of his p.iblished 
works as given in the following list discloses but a part of hi.s.
