rio o General Notes. [November, 
After detailing experiments in raising young from eggs of 
American charr fertilized by Scotch, Dr. Day finally remarks: 
“Considering that these fishes have shown no tendency to 
monstrosities, have been well formed, and grown fairly in propor- 
tion to the young of the true American charr hatched at the 
same time, I cannot resist thinking that it may be possible that 
these two fish, although so widely differing in color, may be 
merely varieties of one species, descendants from one common 
stock. This question, however, will be more appropriately dis- 
cussed when we possess fish a year or two older.” 
ACCELERATION IN DEER ANTLERS.— Besides the white-tailed 
deer mentioned in my note in the July, 1884, number of the Nat- 
URALIST, I have in my collection the antler of a Cervus macrotis 
found near Carter, on the Rocky mountains, which is abnormally 
flattened, which shows no indication of having been injured, and 
so tends to support your position. It is doubly bifurcated. ae 
four inches above the burr it is cylindrical and five and a-hal 
inches in circumference. There it throws off a basal snag re 
inches long. Thence it commences to flatten, and at the 2 
bifurcation, seven inches above the snag, it is six inches pris 
whence the upper prong extends seven inches to its fork, w as 
it is four inches wide. Above this the tines are seven Inc rt 
long, and gradually assume the cylindrical form to their epee
