Should theeffervescence threaten to become explosive, the reaction may be checkedby the further addition of alcohol, and when the reaction appears todecline too much, it may be re-excited by an additional quantity ofacid. By these means, without applying heat, a quantity of nitric*ether will soon be condensed in the refrigerated bottle. To convertthis ether into a liquid, fully equal to the officinal sweet spirits ofnitre, let it

Ti det kan forholdsvislet påvises, at strandflatens ovre grense markeres med en rekkehavdannede huler, og her på den ytterste del av Romsdalshalvøenogså av marine terrasser. Jeg tror dette må være et avgjørendemoment under diskusjonen om strandflatens dannelse. Jeg vilderimoit ikke ha sagt, at hele strandflaten er dannet under den sisteinterglacialtid. Jeg er meget mere av den opfatning, at dannelseav dette mektige abrasjonsplan må føres overordentlig langt tilbakei tiden; men avslutningen må henføres til den
