Prof, Morris — Organic Remains in the Coal, 357 



Bath, but I was not fortunate in finding any similar shales at the 

 other coal-pits visited. Eemains of Entomostraca were, however, 

 tolerably abundant at one or two localities, and I have little doubt 

 would yield a rich harvest to any local investigator. Having 

 submitted the few specimens I obtained to Professor Kupert Jones, 

 that gentleman has kindly determined them. From the bituminous 

 shale of Mr. Farrar's pit at Nailsea ; Estheria striata, var. Beinertiana 

 (Mon. Foss. Estheria3, PL I., Fig. 13), with intercostal spaces dis- 

 tinctly wide, but not shewing ornament ; also an imperfect cast of 

 Beyrichia arcuata f From the roof of the white seam of Youngwood 

 pit, Nailsea, were obtained Kirkhja costata, not in good condition, 

 and partly-imbedded well preserved specimens, of a species of 

 Cythere, as well as some indeterminable casts. In the shale, about 

 200 feet above the white seam of the last pit, was observed an Ostracod 

 imbedded with its surface downwards, closely resembling Cythere 

 fahdina. Numerous seed-vessels {sporangia) were likewise observed 

 in the Coal-shales of Bedminster and Yate, referable probably to 

 Flemingites or Lepidodendron (see Geol. Mag., 1865, Yol. II., p. 433, 

 Plate XII). 



In a letter, just received from Mr M'Murtrie, he states that, " at 

 Eadstock no animal-remains have been found in the Coal-measures, 

 but that at Camerton several specimens of bivalve shells (Antlira- 

 cosiaf) and two specimens of Limulus have been found by Mr E. 

 Feare." J. M.

I, — On the Animals which are most nearly intermediate 

 BETWEEN Birds and Reptiles.^ 



By Professor Huxley, LL.D., F.R.S. 



THOSE who hold the doctrine of Evolution (and I am one of 

 them) conceive that there are grounds for believing that the 

 world, with all that is in it and on it, did not come into existence in 

 the condition in which we now see it, nor in anything approaching 

 that condition. 



On the contrary, they hold that the present conformation and com- 

 position of the earth's crust, the distribution of land and water, and 

 the infinitely diversified forms of animals and plants which con- 

 stitute its present population, are merely the final terms in an im- 

 mense series of changes which have been brought about, in the 

 course of immeasurable time, by the operation of causes more or less 

 similar to those which are at work at the present day. 



Perhaps this doctrine of Evolution is not maintained consciously, 

 and in its logical integrity, by a very great number of persons.^ But

 February 7, 1868. 



2 The only complete and systematic statement of the doctrine with which I am 

 acquainted is that contained in Mr. Herbert Spencer's " System of Philosophy," a 

 work which should be carefully studied by all who desire to know whither scientific 

 thought is tending.
