fancied evolution of one species out of another. When the celebrated anatomist, Camper, first attempted to estimate the degrees of sagacity of different animals, and of the races of man, by the measurement of the facial angle, some speculators were bold enough to affirm, that certain simi differed as little from the more savage races of men, as do these from the human race in general; and that a scale might be traced from apes, with foreheads villanous low, to the African variety of the human

calcareous matter in their stems, to abound near springs impregnated with carbonate of lime. We know that if the common hen be deprived altogether of calcareous nutriment, the shells of her eggs will become of too slight a consistency to protect the contents, and some birds eat chalk greedily during the breeding season. If on the other hand we turn to the phenomena of inorganic nature, we observe that, in volcanic countries, there is an enormous evolution of carbonic acid, mixed with water or

evolution in its elementary form, means nothing more than that everything that exists has been derived from something that pre-existed; that the former is related to the latter as effect is to cause. And it is most pleasing evidence of the acceptibility of this doctrine, that it is now heard from many pulpits in the land, as a strong illustration of the instructions which are thence given. Therefore, while lamenting the death of Darwin, at a ripe old age, and losing the benefit of his vast

CD claimed that the specimens with the largest beaks came from Chatham and Charles Islands, but G. magnirostris has not been found since on those two islands, where either the form has since become extinct, or evolution of beak size has taken place in the manner described by Peter Grant in his book Ecology and Evolution of Darwin's Finches (Princeton

Only at the very end of the voyage were his first thoughts about the immutability of species consciously expressed, but here are to be found the initial seeds of his theory of evolution, and of the fields of behavioural and ecological study of which he was one of the founding fathers.

is the slightest foundation for these remarks the zoology of Archipelagoes will be well worth examining; for such facts would undermine the stability of Species.' Nevertheless, several of the issues to which he often returned earlier may give some indication as to how, albeit subconsciously, his ideas about evolution were taking shape. Thus he always asked himself whether the rats and mice, and other domestic animals, were indigenous or introduced species, and how much variation they displayed

terrestrial animals. He was thus enabled to examine the animals occupying many different environments, and had the very good fortune to be taken by the Beagle to the Galapagos, which turned out eventually to be an ideal place, rivalled only by Hawaii and Madagascar, for studying the evolution of new species in isolated islands. In addition, the Beagle landed him at places where exceptionally informative fossils were lodged in the cliffs, and enabled him to visit the Andes and the coastal plains on

no man more than to Darwin, does the present age owe as much, for the gradual reception of the modern method of close observation over the scholastic or a priori formulae, which, up to a brief period, affected all biological investigations. To him, above all men, we owe the recurrence to the old Aryan doctrine of evolution (though in those ancient times promulgated under the guise of inspiration) as preferable, by reasonable demonstration, to the Shemitic views, which have prevailed to within a

it is not so generally admitted that this was the period of the first evolution of the Botanical Kingdom. It has been affirmed, that no organic remains are found in rocks that were anterior to the coal formation.21 But this idea has been disproved by later discoveries. Some places in England show that the Limestone group below the coal contains vegetable fossils, altho they but rarely occur.22 It is therefore with propriety that the secondary strata, earlier than the coal, have been

that from this commencing nursery, it was gradually disseminated from region to region, according to the laws and qualities of each individual species. The simpler Cryptogamias the lichens and mosses, would diffuse themselves on the barren rocks and mineral surface, to begin the first layers of carbonaceous matter. The Simple Fern tribes would find in this sufficient nourishment for their evolution. Their remains would enable the floating seeds of the Grasses to find a congenial bed for their

The Mollusc and Infusoria have also received a more distinct consideration, and a different arrangement.

Bischof and N ggerath notice a pit, on the side of the lake of Laach, in which they found dead birds, squirrels, bats, frogs, toads, and insects, killed by the evolution of carbonic acid gas. A very copious discharge of carbonic acid gas occurs on the Kyll, nearly opposite Birresborn. The gas rises through fissures of the rock, and traverses a pool of rain-water
