4. " On the Formation of the Cranium among the 

 Patagonians and the Fuegians, with Some Remarks upon 

 American Crania in General" (J. Anat. and Physiol., ii, 

 1868, pp. 253-71. Sci. Mem., iii, xvi, p. 314). 



5. " On Some Organisms Living at Great Depths in 

 the North Atlantic Ocean" (Q. J. Micros. Sci., New 

 Series, viii, 1868, pp. 203-12. Sci. Mem., iii, xvii, 

 p. 330). — The chief scientific interest of this paper is the 

 description of certain indefinite gelatinous masses found 

 in preserved Atlantic dredgings under the name of 

 " Bathybius Haeckelii," supposed to be a primitive 

 organism (" Ur-schleim "). This view, afterwards fully 

 recanted (see p. 154), was founded on one of Huxley's 

 very few observational errors. 



6. "On the Classification and Distribution of the 

 Alectoromorphae [?>., game birds] and Heteromorphae " 

 (Proc. Zool. Soc, 1868, pp. 294-319. Read May 14, 

 1868. Sci. Mem., iii, xix, p. 346).— This important 

 extension of Huxley's work on birds assigns the aberrant 

 South American form Opisthocomus to a separate group 

 (Heteromorphs), most nearly related to game birds and 

 pigeons. It also includes his views on the division of 

 the land into distributional regions, and gives the name 

 " Wallace's Line" to the boundary between the Australian 

 and Oriental realms. 



1869. 



The many-sided activities of 1869 included a further 

 development of Huxley's views on the place of science 

 in education. On April 7, for example, he spoke 

 at the Liverpool Philomathic Society on "Scientific 

 Education : Notes of an After-dinner Speech " (Coll. 

 Essays, iii, p. iii). The lecture alludes to the increas-
