eisiing nur bis zu unseren Endmorånenziigen gereicht haben 

 sollle. Bei alier dankbaren Anerkennung dieser freuiidlichen 

 Courloisie musste ich doch diese Benenniing und iiberhaupt die 

 ganze Teilung in mehrere Eiszeiten zuriickweisen und, der herr- 

 schenden Meinung entgegen, fiir die F2inheitlichkeit des nord- 

 europåischen Glacialpbanomens eintrelen (Geixitz: Die Ent- 

 wicklung der mecklenburgischen Geologie, 1904, pag. 27). 



I Sverige hævdede Holst afgjort, at afsætninger kun fra 

 en istid kunde paavises (Sveriges geol. undersøkn. ser. C. Nr. 

 151, pag. 56). Og i sin »Address lo the Geologicai Section« 

 utlalte Lamplugh: »No proof of mild interglacial epochs, or even 

 of one such epoch, was discovered during the examination of 

 certain typically glaciated distriets in England, Ireland, and the 

 Isle of Man — — — the British evidence for the Interglacial 

 hypolhesis, though requiring further consideration in some di- 

 striets, is nowhere salisfactory. Most of the fossiliferous beds 

 regarded as interglacial contain a fauna and tlora compatible 

 with cold conditions of climate; and in the exceptional cases 

 where a warmer climate is indicated, the relation of the depo- 

 sits to the boulder-clays is open to question«. (British Asso- 

 ciation for the Advancement of Science, York, 1906. Transacti- 

 ons of Section C. Separate Copy. pag 26). Mobkrg og Holst 

 anførte De sydskånska rullstensåsarnes vittnesbørd i frågan om 

 istidens kontinuitet«. Lund 1899. 



Selv i indeværende aar finder vi det centrale Ontario's kvar- 

 tær ganske enkelt inddelt i: 



(1) Post-Glacial or Modern (sands, gravels, stratified clays) 



(2) Glacial or Pleistocene (boulder-clay, etc.) 



(3) Great unconformity 



(Barlow: Corundum, its occurrence, distribution, exploitation, 

 and uses. Ottawa 1915, pag. 44). 



Det er af betydelig interesse, at Chamberlin allerede i 1883 

 ollentligg jorde sit arbeide om »Terminal Moraine of the Second 

 Glacial Epoch» (3rd Annual Report, U. S. Geol. Surv. 1881— 

 '82, pag. 291 fl.) 



De Geer antok lo istider for Skandinaviens vedkommende 

 med en mellemliggende interglacialtid (Sveriges geol. unders. 

 Ser. C. Xr. 68, 1884), likesaa Vogt (Det norske geogr. selsk. 

 aarbok, HI (1891—1892), pag. 34 flg.) og hkesaa Wille (Natu- 

 ren 1915, pag. 180—181). 



I en fremstilling af »Physiographic development of the 

 Cascade Ranges finder vi opført: — 



(1) Post-Glacial to Present (Resent) 



(2) Latest Glacial F^poch (Pleistocene) 



(3) Inter-Glacial
