When, after singing a great solo, to salvos of applause, Mademoiselle Klosking took the second part with this urchin, the citizens and all the musical people who haunt a cathedral were on the tiptoe of expectation. The boy amazed them, and the rich contralto that supported him and rose and swelled with him in ravishing harmony enchanted them. The vast improvement in the boy's style did not escape the hundreds of persons who knew him, and this duet gave La Klosking a great personal popularity.英文原著 · 《A Woman-Hater》

The fact that in nuclei containing chromosomes of various sizes, the chromosomes which pair together in reduction-division are always of equal size, constitutes a further and more important proof of their qualitative difference.

Very instructive series may also be observed among the Echinoderms and, what is very rare, we are able in this sub-kingdom to demonstrate the derivation of one class from another.
