eisung nur bis zu unseren Endmorånenziigen gereicht haben 

 sollle. Bei aller dankbaren Anerkennung dieser freundlichen 

 Courtoisie musste ich doch diese Benennung iind uberhaupt die 

 ganze Teiluug in mehrere Eiszeiten zuriickweisen und, der herr- 

 schenden Meinung entgegen, fiir die Einheitlichkeit des nord- 

 europåischen Glacialphånomens eintreten« (Geinitz: Die Enl- 

 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 to the Geological Section« 

 uttalte 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 

 hypothesis, though requiring further consideration in some di- 

 striets, is nowhere satisfactory. Most of the fossiliferous beds 

 regarded as interglacial contain a fauna and flora 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). Moberg og Holst 

 anførte »De sydskånska rullstensåsarnes vittnesbørd i frågan om 

 istidens kontinuitet*. Lund 1899. 



Selv i indeværende aar finder vi det centrale Ontarios kvar- 

 tser ganske enkelt inddelt i: 



(1) Post-Glacial or Modern (sands, gravets, 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 

 offentliggjorde 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 to istider for Skandinaviens vedkommende 

 med en mellemliggende interglacialtid (Sveriges geol. unders. 

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

 aarbok, III (1891—1892), pag. 34 flg.) og Hkesaa Wille (Natu- 

 ren 1915, pag. 180—181). 



I en fremstilling af »Physiographic development of the 

 Cascade Range «, finder vi opført: — 



(1) Post-Glacial to Present (Resent) 



(2) Latest Glacial Epoch (Pleistocene) 



(3) Inter-Glacial
