the leg from the knee to the hoof, which was perfect, and the 
hair was tan colour and short." 
The recent existence of the Megaceros is also inferred from 
some of the localities in which its bones are found being the 
sites of lakes, known as such during historic times. In 
Ireland these situations are generally connected with the 
remains of ancient forts, to which I shall shortly refer. In 
the Isle of Man the limited district named Ballaugh, from 
whence the- greatest number of bones have been procured, 
is, according to Dr. Hibbert, nothing more than a corruption 
of the name Balla Lough or Lake, the place of the lake, 
one of which remained at so recent a date as to be actually 
described in a map of the Isle of Man, published in 1656, 
by James Chaloner, in which, other ancient lakes, now 
obliterated, are also marked down and named. The 
existence of other large lakes, within the historical period, 
is attested by ancient records, and is inserted in a map of 
the island, prepared as early as 1595. 
Lough or Loch Gur, a lake near Limerick, where numerous 
bones have been found, is said to be particularly noticed in 
Pepper's History of Ireland. These sites are generally indi- 
cated by a wet hollow or morass, filled with aquatic plants, as 
the Equisetum, and others of a similar character ; and, when 
the lacustrine marl is penetrated through, are suddenly inun- 
dated with water from the subsoil. The calcareous tuffa may 
be partially derived from the relics of fresh-water shells which 
abound and breed in lakes, and even the shallowest pools; and 
as their death and reproduction is very rapid, a considerable 
amount of calcareous matter is speedily accumulated. 
Not the least extraordinary circumstance connected with 
the history and extinction of this animal, is the singular fact 
that it appears to have been almost exclusively confined to 
two isolated spots — Ireland and the Isle of Man ; for as I 
have already stated, although it has occurred in various parts 
of the kingdom, these examples have been fragmentary, and,
