APPENDIX. 
AT the last moment, I am enabled to present in this form the follow- 
ing abstract of a paper by Mr. Robert Morrow, read before the Institute 
of Natural Science, Halifax, N. S., April 9, 1877, deeply regretting that 
I was not enabled to present its important facts in the text. Mr. Mor- 
row’s examination and description of the cyst in the neck of the Caribou, 
first mentioned by Hutchins, and his comparison of it with that found 
by Mr. Camper in the Reindeer, are of especial value. His observations 
are made with an intelligent care, and described with a particularity, 
which enable us to understand the subject almost as if we had made the 
examination ourselves. 
The examination of the interdigital glands or tubes between the toes 
of the Caribou and the Moose, by himself and Drs. Gilpin and Sommers, 
are of very great importance, and were evidently made with great care 
and intelligence. In the text I have suggested the probability that these 
members would be found wanting in the Moose, as I had found them 
wanting in the wapiti deer. This paper of Mr. Morrow settles that 
matter, and shows that they exist in the Moose to about the extent they 
are found in the Caribou. With this new and important information 
before us, I may here repeat, that these glands, which are found in the 
feet of deer, and are wanting in the feet of all other ruminants, so far as 
I am informed, lack the constancy, and heuce reliability of the other 
glandular members peculiar to the Cervide. 
Mr. Morrow deserves our thanks for this valuable contribution to 
zoological science. He informs me that a similar abstract has been fur- 
nished to “ Forest and Stream,” in which it will shortly appear. 
Abstract of a Paper, read April 9, 1877, before the Institute of Natural Science, 
Halifax, N. S., by R. Morrow, entitled “ Notes on the Caribou.” 
Mr. Morrow said, that the paper owed its origin to the following quotation 
from Sir John Richardson’s ‘* Fauna Boreali-Americana,”’ pages 250 and 251. 
Mr. Hutchins “mentions that the buck (Caribou) has a peculiar bag or cist 
on the lower part of the neck, about the bigness of a crown piece, and filled 
with fine flaxen hair, neatly curled round to the thickness of aninch. There 
is an opening through the skin, near the head, leading to the cist, but Mr. 
Hutchins does not offer a conjecture as to its uses in the economy of the ani-
