Blyth, which have recently been endorsed and amplified by R.
But a bolder attempt at classification was that made in 1838 by Blyth in the New Series (Charlesworth's) of the Magazine of Natural History (ii.
It is plain that Blyth saw, and perhaps he was the first to see it, that geographical distribution was not unimportant in suggesting the affinities and differences of natural groups (pp. 258, 259); and, undeterred by the precepts and practice of the hitherto dominant English school of Ornithologists, he declared that " anatomy, when aided by every character which the manner of propagation, the progressive changes, and other physiological data supply, is the only sure basis of classification."
It is obvious that both these investigators had the genius for recognizing and interpreting the value of characters; but their labours do not seem to have met with much encouragement; and a general arrangement of the class laid by Blyth before the Zoological Society at this time 1 does not appear in its publications.
Its line to some extent may be partly made out - very clearly, for the matter of that, so far as its details have been published in the series of papers to which reference has been given - and some traces of its features are probably preserved in his Catalogue of the specimens of birds in the museum of the Asiatic Society of Bengal, which, after several years of severe labour, made its appearance at Calcutta in 1849; but, from the time of his arrival in India, the onerous duties imposed upon Blyth, together with the want of sufficient books of reference, seem to have hindered him from seriously continuing his former researches, which, interrupted as they were, and born out of due time, had no appreciable effect on the views of systematisers generally.
The association of Alcedo with the other two is no doubt a 'misplacement, but the alliance of Buceros to Upupa, already suggested by Gould and Blyth in 1838 4 (Mag.
Blyth " arrived at the same conclusion, however, by a different train of investigation," and this is beyond doubt.
X.-xii.), while Blyth and Nitzsch had (as already mentioned) seen some of their value in classification.
More than this, he entered upon their geographical distribution, the facts of which important subject are here, almost for the first time, since the attempt of Blyth already mentioned, 4 brought to bear practically on classification.
It lies on high ground above the river Blyth, 22 m.
These consist of galactin and lactochrome, substances peculiar to milk, discovered by Winter Blyth, with certain animal principles such as leucin, pepton, kreatin, tyrosin, &c. The salts in milk consist, according to the average of numerous analyses by Fleischmann, of the following Milk thus is not to be regarded as a definite chemical compound nor even as a mixture of bodies in fixed and invariable proportions.
BLYTH, a market town and seaport of Northumberland, England, in the parliamentary borough of Morpeth, 9 m.
Of that town, at the mouth of the river Blyth, on a branch of the North Eastern railway.
Blyth is also in considerable favour as a wateringplace; there are a pleasant park, a pier, protecting the harbour, about i m.
The river Blyth rises near the village of Kirkheaton, and has an easterly course of about 25 m.
Blyth long ago proposed the name Caprolagus for the remarkable spiny rabbit of the western Himalayas, while the generic name Oryctolagus was suggested later for the rabbit, and Sylvilagus for the American "cotton-tails"; but none of these was accorded general acceptation.
The spiny rabbit, separated from Lepus by Blyth in 1845 under the name of Caprolagus hispidus, is an inhabitant of Assam and the adjacent districts, and distinguished by its harsh, bristly fur and short ears and tail.
According to Blyth, it is a favourite amusement among the natives to let loose a couple of tame caracals among a flock of pigeons feeding on the ground, when each will strike down a number of birds before the flock can escape.
Blyth was included with North Shields till 1897.
The principal ports for the shipping of coal for export, set down in order of the amount shipped, also fall very nearly into topographical groups, thus: - Newcastle, South Shields and Blyth in the Northern District; Newport in Monmouthshire; Sunderland in the Northern District, Hull, Grimsby and Goole on the Humber, which forms the eastern outlet of the Yorkshire coal-fields; Hartlepool, in the Northern District, and Liverpool.
Blyth relied in separating the Tibetan lynx (L.
