cap. 3.), about which period it probably became extinct, although the credu- 
lous Boece states that they were found in plenty so late as the 15th century. 
It was termed by the Welsh in the 9th century Leges Wallicse,” iii. 1 1. 12.) 
Llosdlydan^ and in the Gaelic it is still termed, from tradition, Losleathen. See 
Mr Neill’s valuable “ Account of some fossil remains of the Beaver found in 
Perthshire and Berwickshire,” Wern. Mem. iii. p. 207- The bones of this 
species occur in beds of marl under peat-moss, as quoted by Mr Neill ; and 
in Berkshire, Phil. Trans. 1757? p* 112. 
The Guinea pig ( Cavia Cobaya has been domesticated in the belief that 
its smell will expel rats. It is a native of Brazil, and may be regarded as a 
useless addition to our stock of quadrupeds. 
PECORA. 
I. Horns permanent^ furnished internally with an osseous 
core. 
Gen. XXII. BOS. Ox. — Horns lateral at their origin, but 
afterwards recurved, smooth. 
36. B. Taurus. Common Ox. — Front flat, longer than 
broad. Horns proceeding from the extremities of the occipital 
ridge. 
The cow goes with young nine months, and is capable of breeding the se- 
cond year. Milk teeth begin to shed about the tenth month. Numerous va- 
rieties exist at present in a domesticated state, differing in colour and shape, 
and in the form or absence of their horns. Those in the more fertile districts 
are the largest ; those frequenting mountainous districts with scanty pastures 
are the smallest, with the fore-quarters proportionally larger, as in Zetland. 
Several varieties, if not species, of oxen appear to have occupied the Bri- 
tish Island, in a wild state, at no very remote period. I..esley De Origine, 
moribus et rebus gestis Scotorum,” Home 1G78) mentions herds of“ Vaccee 
non cicures,'’'' (p. 10.), which frequented the mountainous districts of Argyle 
and Ross. These probably were the parent stock of our domesticated varie- 
ties, which, with but little care, are reared in the remoter districts. 
The “ boves sylvestres" of Lesley (p. 19.), which were of a white colour, pos- 
sessed, as he states, “ jubam densam, ac dimissam instar leonis while Sir 
Robert Sibbald says, that, in his day, they did not differ in form from the 
common kind. The remains, however, of this white breed, with the muzzle 
and ears black, may be found mixed occasionally in our domestic kind. In a 
pure state, they are preserved in the parks of a few of the nobility. The 
remains of oxen, which occur in marl-pits in this country, seem all to belong 
to the species taurus. Many of the skulls, however, exhibit dimensions su- 
perior to those of the largest domesticated kinds. A skull in my possession 
measures 27| inches in length, 9 inches between the horns, and 11^ inches 
across at the orbits. 
The manes, which several authors state to have characterised the wild oxen 
of this country, and their remarkable ferocity, probaaiv had a reference to 
the Bos Urus, a species once indigenous, as attested by the occurrence of its 
remains in the recent strata. A skull of this species, found by Mr Warbur- 
ton, at Walton in Essex, forms a part of the Collection of the Geological So- 
ciety of London, and another skull found at Woolwich, exists in the Museum 
of the Royal College of Surgeons, I^ondon. This species differs remarkably 
from the Bos Taurus^ in the front being swollen, broader than long, the horns
