respect to their stratagraphical relations, still taken in conjunction _ 
with the Shandon remains, it is not improbable that they 
belong to the horse of the Mammoth period, which may, like the 
wolf, have survived long after many of its contemporaries 
died out. 
The Rhinoceroses of English strata seem entirely wanting in 
Scotch and Irish deposits. 
HIPPOPOTAMUS. 
The only relic referable to this ungulate and of reputed Irish 
origin is a tooth said to have been discovered near Carrickfergus 
in 1837. The details as to the find are given by Dr. Moore, 
M.R.1.A., who was in Belfast at the time, and there is, moreover, 
a drawing of it in the office of the Geological Survey of Ireland 
by the late M. Du Noyer. It is clearly a lower canine of Hippo- 
potamus, but, unfortunately, the specimen is lost, and Dr. Moore, 
although he recognises the drawing as that of the tooth in ques- 
tion, cannot absolutely confirm the statement of the finder. It 
is important to notice that Dr. Moore in his letter to Professor 
Hull calls it an “elephant’s tooth,” which mistake is copied by 
Professor Hull in his Address ;* however, as shown by Dr. 
Scouler, it was well known at the time of discovery to belong 
to Hippopotamus.t 
WILD HOG (Sus scrofa). 
Although not hitherto found in a fossil state, or associated with 
remains of the extinct mammals, the hog, according to ancient 
historians, was very plentiful in the woods and forests of Ireland. 
Girald Barry says “they were numerous, small, deformed, and 
cowardly.”{ Sir William Wilde in his interesting paper on “The 
unmanufactured animal remains belonging to the Academy” § 
furnishes a summary of the historical references in connexion 
with the animal, which may possibly have been introduced.

This tooth is said to have been found by a son of the late Mr. Doran, who was in the 
habit of selling specimens of natural objects to the Palxontological department of the 
Geological Survey.
