suggest the Coél’s to be a Ouculine egg of some kind, from a cer- 
tain resemblance in its appearance to the Cuckoo’s ege, which at 
once strikes the observer. Filling several blown egg shells of the 
Coél with water, they were found thus to weigh, from 100 to 120 
grains each, generally about the latter; those of Corvus splendens 
we found thus to vary, from 180 to 245 grains, and those of C. eul- 
minatus, from 235 to 305 grains.*” 
The following observations, in a letter from a missionary friend 
to Mr. Blyth, also bear on the subject. ‘ With respect to the Crow 
discovering that the bird it has reared is an interloper, and conse- 
quently ejecting it from the nest, you seem to have doubts, on 
account of the anecdote related by Major Davidson. Now, against 
this, I have to bring my own testimony, and that of an intelligent 
native, who from his youth has been a keen sportsman and bird 
fancier. He is also a man of undoubted veracity. He states, 
that after the Coél has laid its egg in the Crow's nest, it comes 
often to watch the nest, from a little distance, to see when its 
young is expelled, This happens as soon as it puts on its speckled 
dress, which is, when it is fledged, Ag soon as it is driven away, 
the mother takes her young into her charge and feeds it. This 
he has often observed, being in the habit of watching these birds 
when at Gwaliér. This statement is confirmed by others. 
“As to the mother feeding her young, I have seen it myself. 
The young, though full grown, sat quitely in a peepul tree, while 
its mother hunted for fruit, and she several times fed it before 
me. I watched them near at hand for some time, and at last they 
both flew away, the mother uttering, as she flew, her well known 
cry. Ihave since seen full grown young Coéls feeding themselves 
alone.”’ 
The truth, we apprehend, is, that the Coél produces a series of 
several eggs, at intervals of two or three days, like the Europea? 
Cuckoo, and as they are hatched, and the young ejected in suc- 
cession, she takes charge of each of the latter in turn, and feeds it 
for a day or two only, by which time it learns to shift for itself, 
but we begnes that we have not had the leisure to obgerve more 
m propria persona.
