On entering one of these fissures from the bed of the little stream near Buree and following, to a considerable distance, the subterraneous channel of the rivulet, we found a red breccia containing bones as abundantly as that of Wellington Valley. It occurred also amidst masses of broken rocks, between which we climbed until we saw daylight above and, being finally drawn out with ropes, we emerged near the top of a hill from a hole very similar in appearance to the mouth of the cave at Wellington, which it also resembled in having breccia both in the sides of the orifice and in the surface around it.

AT MOLONG.

At Molong, 36 miles east of Wellington Valley, I found some concreted matter within a small cavity of limestone rock on the surface and, when broken, this proved to be also breccia containing fragments of bone.

SHATTERED STATE OF THE BONES.

It was very difficult to obtain any perfect specimens of the remains contained in the breccia--the smallest of the various portions brought to England have nevertheless been carefully examined by Professor Owen at the Hunterian Museum, and I have received from that distinguished anatomist the accompanying letter containing the result of those researches and highly important determinations by which he has established several points of the greatest interest as connected with the Natural History of the Australian continent.

IMPORTANT DISCOVERIES BY PROFESSOR OWEN.

Dear Sir,

I have examined, according to your request, the fossil remains which you discovered in Wellington Valley, Australia, and which are now deposited in the Museum of the Geological Society; they belong to the following genera:
