In Zirhæa (Lamellibranch) the process is identical, although more 
obvious by reason of the less close apposition of the halves of the rings 
and V’s. The conclusion is that in both forms a reducing division 
takes place.

Upon behalf of the Committee appointed to draw up a resolution 
relating to the death of Professor Cope, Professor Osborn delivered a 
brief eulogy of the great naturalist, pointing out the especial features 
which have made his work famous and have given him such a high 
position in the history of Natural Science. He dwelt especially upon 
the fact that Professor Cope prosecuted five great lines of work simul- 
taneously, and that in each he acquired a commanding position. He 
also spoke of some of his generous qualities as a fellow scientific worker, 
especially his liberality in the loan of collections and generous recogni-

pendence and fortitude of character, and persistent devotion to science, 
even with limited resources. His death leaves a vacuum especially in 
the line of able and accurate criticism of contemporary work. Pro- 
fessor Osborn concluded by submitting the following resolution : 
The members of the New York Academy of Sciences desire to record 
their admiration of the noble services to Science of the late Professor 
Edward D. Cope. Since 1859, when he offered his first contribution to 
the Philadelphia Academy of Sciences, at the age of nineteen, he has 
been a devoted and brilliant investigator in five great branches of 
Natural History, ichthyology, herpetology of the batrachians and 
reptiles, mammalian paleontology, historical geology and philosophy. 
In each he has long been an acknowledged leader, and his combined 
knowledge of all has given his researches a philosophical breadth, grasp 
and permanence, which place him among the great masters of Compara- 
tive Anatomy, Cuvier, Owen and Huxley. We deeply regret that his 
untimely death has cut short his life work, and feel that the loss of his
