Page 116 - It was one of the most ancient as well as one of the most interesting places in sacred record.
Page 14 - The surface is irregular, occasionally rising into rounded lobes ; the efferent canals are deeply channeled in the upper surface of the sponge, five or six sometimes converging to a common orifice. The statospheres are numerous — rather small.
Page 317 - Palaearctic or of the Neotropical regions. Professor Huxley and Mr. Blyth advocate the former course ; Mr. Andrew Murray (for mammalia) and Professor Newton (for birds) think the latter would be more natural. No doubt much is to be said for both views...
Page 346 - Origin of sedias to whether they were originally deposited as such, or in some other tit(?s- — form, and afterwards altered to magnetite. It seems possible that, in some cases, beds may have been formed by the accumulation of iron sands, just as they are forming in the Gulf of St. Lawrence to-day, the material being derived from the disintegration of pre-existing crystalline rocks.
Page 207 - Margaritella, and the sub-genus Anchura, of the genus Aporrhais, are all recognized as strictly characteristic of the cretaceous; so much so, that the presence of a single undoubted representative of either of these genera would be strong presumptive evidence of the cretaceous age of any rocks in which it might be found.
Page 197 - HEILPRIN. The controversy which for a long time was maintained between Conrad and Gabb as to the age of the Tejon rocks of California, referred by the former to the eocene series, and by the latter considered to represent the uppermost member of the cretaceous (Division B of the California Report), can scarcely be considered to have settled the question at issue.

Page 110 - Wilcox found the parasites in four out of six birds examined. In the present specimen of a head a single worm is enclosed between the two laminae of the dura mater over the position of the interval of the cerebrum and cerebellum. As the parasite appears not to have been named, it was suggested that the name of its discoverer should be associated with it under the name Filaria wymani.
