TUBES IN THE FEET OF THE MOOSE — MORROW. 161 



rest with the palmar surfaces of their extremities upon the land, 

 because there is greater freedom of leg and arm than in our 

 seals. They move more freely and with greater rapidity when 

 on land, nevertheless their movements are on the whole very 

 similar to those of our own species. 



Note. — The tentorium cerebellum partly of bone as in cat, falx cerebri at its junction with 

 tentorium also formed of bone.

Read Mvy 10th, 1880. 



In April, 1877, 1 read to you some " Notes on the Caribou," 

 (see vol. 4, Transactions N. S. 1. N. S., page 281, et seq.,) in 

 which I drew your attention to the tubes in the feet of the 

 moose. I shot last December an old cow moose, in the hind feet 

 of which the tubes were fully developed, but differed from those 

 in the hind feet of the bull described by me (see page 292, 

 ibid,) in being more perfect in shape, closely resembling the 

 tubes in the hind feet of the old doe caribou, that is, being much 

 narrower and more perfectly defined in their mouths, and of 

 nearly equal diameter to their inferior extremities, also being 

 very strongly marked, as in the caribou, by the coarse, bristly 

 tufts of hair which issue from their mouths. The inferior ex- 

 tremities of the tubes are attached, as in the caribou, by strong 

 fascia to the superior surface of the skin of the web, or soles of 

 the feet. 



In the fore feet the tubes were nearly obliterated, existing 

 only as a slight depression in the skin, about one inch in length, 

 the tube proper being so reduced as scarcely to be perceptible • 

 this depression, lying between the phalanges, is attached as in 

 the hind feet, by fascia to the sole, but the fascia extends to 

 the middle of the depression, marking what was originally the 

 lower extremity of the tubes, and it is therefore of greater length 

 than that in the hind feet. There were no bristly tufts marking 

 the tubes in the fore feet of this cow moose, as are in the fore 

 feet of the doe caribou.
