"The question you ask is one of great ornithological
importance and I believe has never been worked out, but I am absolutely
afraid to ask any questions in the British Museum, as they jump at an
idea and cut the ground from under the original man's feet. This I
regret to say is my experience. I have been asked what does it matter
who makes the discovery? I reply, 'Render unto Caesar, etc.' If you are
going to work it out, keep it dark. The British Museum have not the
necessary specimens--in this country I believe it is not known how the
change takes place. I tried some years ago to work it out with live
specimens, but failed because I could not get young birds. Now in answer
to your question, my belief is that the young bird moults into the
winter plumages direct and that this is changed into the full plumage in
spring either by a spring moult or by a shedding of the tips of the
feathers. This is private because it is theoretical, and for your
private use to verify...."
Of the Finland seal, by the way, Dr. Guenther wrote: "The skin differs in
nothing from that of Phoca foetida. In the skull I observe that the
nasal bones are conspicuously narrower than in typical specimens from
the northern coasts. There is also a remarkable thinness of bone, a want
of osseous substance; but it is impossible to say whether this is due to
altered physical conditions or should be accounted for by the youth of
the specimen, or whether it is an individual peculiarity."
