Robert Brown, as we have seen, penetrated more deeply than most of his contemporaries into the secrets of nature, and he enriched the science to which he devoted his long life by discoveries of fundamental importance. But he, no more than others, was able to anticipate, with all his insight, the recognition of the broader bonds of coherence which link up the plant kingdom as a whole. That was only made possible when the researches of Hofmeister, the great Tübingen Professor, had been made known to the world. But it is no reproach to his memory or to his reputation that he should have fallen into error when attempting to elucidate the critical stages in the life history of cryptogams. The historical interest attaching to his mistakes lies in their inevitableness at the time when he was actively working. It would be as ungracious as it would be futile to attempt to rob the great botanist of the meed of praise which by all that is right belongs to him, because he could not escape from the influence of limiting factors. His supreme merit rests in his wonderful elucidation of the morphology and inter-relationships of the higher plants, and if we judge him by his achievements in this field we shall hardly disagree with v. Humboldt in according to him the title of _Facile Botanicorum princeps, Britanniae gloria et ornamentum_. SIR WILLIAM HOOKER 1785-1865 BY F. O.

"Poeta nascitur non fit." A poet is born, not made. If this be true of poets, much more is it true of botanists. The man who takes up botany merely as a means of making a livelihood, rarely possesses that true spirit of the naturalist which is essential for the highest success in the Science. It is the boys who are touched with the love of organic Nature from their earliest years, who grub about hedgerows and woods, and by a sort of second sight appear to know instinctively, as personal friends, the things of the open country, who provide the material from which our little band of workers may best be recruited.
