As As 1872 | And, as 1859 1860 1861 1866 1869 |
in the case of flowers, I have as yet failed, after consultation with one of the highest authorities, namely, Professor Huxley, to discover a single

I have been enabled, by a fortunate chance,
....... 1872 | elsewhere 1859 1860 1861 1866 1869 |

It must have struck most naturalists as a strange anomaly that,
