1866.] Biology. 541 
In his “Report on Dredging amongst the “Hebrides,” Mr. 
Gwyn Jeffreys called attention to certain geological considerations 
of high theoretical interest, and which produced an animated dis- 
cussion. 
Dr. Le Neve Foster stated that the facts of the “ Curious Lode 
or Mineral Vein in New Rosewarne Mine, Gwinear, Cornwall,” led 
him to infer that the fissure which it occupied had been filled partly 
mechanically and partly chemically, and that the various deposits 
had been introduced at six different times. The vein, however, was 
chiefly remarkable on account of its containing rounded pebbles. 
Dr. Beke gave a brief account of the island of St. John, in the 
Red Sea. 
Bionogy. (Section D.) 
The title “Biology” was this year adopted for Section D in place 
of the old one “ Zoology and Botany,” and it was recommended by 
the Council of the Association that two special departments should 
be added to it,—one of Physiology and another of Anthropology. 
Accordingly Section D had three places of meeting, in which 
papers were simultaneously read. A large number were thus 
disposed of, equal in amount to those of any three of the other 
Sections. 
Professor Huxley presided over the Section, while Professor 
Humphry, of Cambridge, took charge of the Physiological, and 
Mr. Wallace, the traveller, of the Anthropological department. 
On the second day of meeting of the Sections, the departments 
of Section D were summoned to meet in one room, in order to 
hear an address from Professor Huxley on the classification and 
scope of the Biological Sciences, with especial reference to the 
arrangements made with regard to the departments of Section D. 
The President commenced by observing that he was afraid some 
present would be disappointed, as he did not anticipate any 
controversy, nor any heresy. If any persons should be induced to 
leave the room in consequence of that statement, he should be very 
glad. He then proceeded to discuss the nature of Biological 
Science. All Biological inquiries resolved themselves into either 
the study of form simply, or the reason of that form’s occurrence. 
The Embryologist studied a series of forms only, the Anatomist and 
Histologist studied form, Histology being assuredly nothing but 
the anatomy of minute parts. The Taxonomist arranged and 
classified animals with regard to the forms which they presented ; 
the subject of distribution related to the position occupied by 
various forms of life at the present time on the surface of the
