Moreover, as Gartner repeatedly crossed some forms, such as the common red and blue pimpernels (Anagallis arvensis and coerulea), which the best botanists rank as varieties, and found them absolutely sterile, we may doubt whether many species are really so sterile, when intercrossed, as he believed.

Moreover, as Gartner during several years repeatedly crossed the primrose and cowslip, which we have such good reason to believe to be varieties, and only once or twice succeeded in getting fertile seed; as he found the common red and blue pimpernels (Anagallis arvensis and coerulea), which the best botanists rank as varieties, absolutely sterile together; and as he came to the same conclusion in several other analogous cases; it seems to me that we may well be permitted to doubt whether many other species are really so sterile, when intercrossed, as Gartner believes.

The unfortunate loss of his expedition-boat made the journey to Boothia and King William's Land impossible; but Mr. Hall's prolonged existence during nearly three years among the "Innuits" determined his immediate departure again for those regions as soon as he could return and be properly fitted out for a second trip from the "States."

He may love some consecrated rite as being pure and beautiful, or even because other hearts have loved it,—the rite is permitted, not commanded by God—he may express God by terms of co-equality and consubstantiality, and even desire to proclaim such expressions, in concert with like-minded persons, to the harmonies of an organ, so long as it uplifts him in spirit; but such a man falls into a grievous error when he vilifies or condemns others for not seeing as he does, or enunciates that thus and thus only can a man apprehend God.
