000 SUPPLEMENTARY NOTES. 
Beds of limestone, occupying a similar geological position, and 
containing the same organic remains, (some of which belong to 
the well known deposit at Burdie House, near Edinburgh), have 
more recently been recognized at Ardwick, near Manchester; 
these beds were identified with those of Shropshire, by Professor 
Phillips (Brit. Assoc. Adv. of Science, 1836), and have also 
been described by Mr. Williamson, Phil. Mag. October, 1836. 
P. 75, Note, and 491, Note, The Coal of Biickeberg, in 
Nassau, respecting which various opinions have been enter- 
tained, some referring it to the Green sand, and others to the 
Oolite series, has been determined by Prof. Hoffmann to belong to 
the Wealden Fresh-water formation.

P. 88. An account has recently been received from India of 
the discovery of an unknown and very curious fossil ruminating 
animal, nearly as large as an Elephant, which supplies a new 
and important link in the Order of Mammalia, between the 
Ruminantia and Pachydermata. A detailed description of this 
animal has been published by Dr. Falconer and Captain Cautley, 
who have given it the name of Sivatherium, from the Sivalic or 
Sub-Himalayan range of hills in which it was found, between 
the Jumna and the Ganges. In size it exceeded the largest 
Rhinoceros. The head has been discovered nearly entire. The 
front of the skull is remarkably wide, and retains the bony cores 
of two short thick and straight horns, similar in position to those 
of the four horned Antelope of Hindostan. The nasal bones are 
salient in a degree without example among Ruminants, ex- 
ceeding in this respect those of the Rhinoceros, Tapir, and 
Palseotherium, the only herbivorous animals that have this sort 
of structure. Hence there is no doubt that the Sivatherium was 
invested with a trunk, and probably this organ had an interme- 
diate character between the trunk of the Tapir and that of the 
Elephant. Its jaw is twice as large as that of a Buffalo, and 
larger than that of a Rhinoceros. The remains of the Siva- 
therium were accompanied by those of the Elephant, Mastodon, 
Rhinoceros, Hippopotamus, several Ruminantia, &c.
