The descriptions were at first extremely inartistic and unmethodical; but the effort to make them as exact and clear as was possible led from time to time to perceptions of truth, that came unsought and lay far removed from the object originally in view. It was remarked that many of the plants which Dioscorides had described in his Materia Medica do not grow wild in Germany, France, Spain, and England, and that conversely very many plants grow in these countries, which were evidently unknown to the ancient writers; it became apparent at the same time that many plants have points of resemblance to one another, which have nothing to do with their medicinal powers or with their importance to agriculture and the arts. In the effort to promote the knowledge of plants for practical purposes by careful description of individual forms, the impression forced itself on the mind of the observer, that there are various natural groups of plants which have a distinct resemblance to one another in form and in other characteristics. It was seen that there were other natural alliances in the vegetable world, beside the three great divisions of trees, shrubs, and herbs adopted by Aristotle and Theophrastus. The first perception of natural groups is to be found in Bock, and later herbals show that the natural connection between such plants as occur together in the groups of Fungi, Mosses, Ferns, Coniferae, Umbelliferae, Compositae, Labiatae, Papilionaceae was distinctly felt, though it was by no means clearly understood how this connection was actually expressed; the fact of natural affinity presented itself unsought as an incidental and indefinite impression, to which no great value was at first attached. The recognition of these groups required no antecedent philosophic reflection or conscious attempt to classify the objects in the vegetable world; they present themselves to the unprejudiced eye as naturally as do the groups of mammals, birds, reptiles,

The historians of botany have overlooked the real state of the case as here presented, or have not described it with sufficient emphasis; due attention has not been paid to the fact, that systematic botany, as it began to develope in the 17th century, contained within itself from the first two opposing elements; on the one hand the fact of a natural affinity indistinctly felt, which was brought out by the botanists of Germany and the Netherlands, and on the other the desire, to which Cesalpino first gave expression, of arriving by the path of clear perception at a classification of the vegetable kingdom which should satisfy the understanding. These two elements of systematic investigation were entirely incommensurable; it was not possible by the use of arbitrary principles of classification which satisfied the understanding to do justice at the same time to the instinctive feeling for natural affinity which would not be argued away. This incommensurability between natural affinity and a priori grounds of classification is everywhere expressed in the systems embracing the whole vegetable kingdom, which were proposed up to 1736, and which including those of Cesalpino and Linnaeus were not less in number than fifteen. It is the custom to describe these systems, of which those of Cesalpino, Morison, Ray, Bachmann (Rivinus), and Tournefort are the most important, by the one word ‘artificial’[1]; but it was by no means the intention of those men to propose classifications of the vegetable kingdom which should be merely artificial, and do no more than offer an

"Is that an answer for me, you ——," and here he called me a name, bad enough for a living man, but to the last degree insulting to one in my condition, and with this he pointed his pistol straight between my eyes.

It has always been the chief hindrance to a more rapid advance in botany, that the majority of writers simply collected facts, or if they attempted to apply them to theoretical purposes, did so very imperfectly. I have therefore singled out those men as the true heroes of our story who not only established new facts, but gave birth to fruitful thoughts and made a speculative use of empirical material. From this point of view I have taken ideas only incidentally thrown out for nothing more than they were originally; for scientific merit belongs only to the man who clearly recognises the theoretical importance of an idea, and endeavours to make use of it for the promotion of his science. For this reason I ascribe little value, for instance, to certain utterances of earlier writers, whom it is the fashion at present to put forward as the first founders of the theory of descent; for it is an indubitable fact that the theory of descent had no scientific value before the appearance of Darwin’s book in 1859, and that it was Darwin who gave it that value. Here, as in other cases, it appears to me only true and just to abstain from assigning to earlier writers merits to which probably, if they were alive, they would themselves lay no claim.

“There is a God! there is a God! Lord have mercy on my soul!”

“Nothing—says I—but won’t you be ating a bite Mr. Johnny.”

two types—the new type, highly qualified, official, administrative, scientific, public-spirited; the old type, capitalistic, with a pretentious house and equipment, the doctor with a brougham, and a dispensary, the schoolmaster or schoolmistress with some huge old stucco house converted by jerry-built extensions to meet scholastic needs. Who would not rather, one may ask, choose the former way who was not already irrevocably committed to the latter? Well, I with my Socialist dreams would like to answer “No one,” but I’m learning to check my buoyant optimism. The imagination and science in a young man may cry out for the public position, for the valiant public work, for the hard, honourable, creative years. He may sit with his fellow-students and his fellow-workers in a nocturnal cloud of tobacco smoke and fine talk, and vow himself to research and the creative world state. In the morning he will think he has dreamed; he will recall what the world is, what Socialists are, what he has heard wild Socialists say

Now among the visible objects which hint to us fragments of this infinite secret for which our souls are waiting, the faces of women are those that carry the most legible hieroglyphics of the great mystery. There are women’s faces, some real, some ideal, which contain something in them that becomes a positive element in our creed, so direct and palpable a revelation is it of the infinite purity and love. I remember two faces of women with wings, such as they call angels, of Fra Angelico,——and I just now came across a print of Raphael’s Santa Apollina, with something of the same quality,——which I was sure had their prototypes in the world above ours. No wonder the Catholics pay their vows to the Queen of Heaven! The unpoetical side of Protestantism is that it has no women to be worshipped.

The day was a glad one at the White House. The




He came to an abrupt pause, as his eye was caught by the key of the desk itself, to which a dirty envelope was affixed. Poirot frowned at it and withdrew it from the lock. On it were scrawled the words: “Key of Roll Top Desk,” in a crabbed handwriting, quite unlike the neat superscriptions on the other keys.


“It’s all over!” said Jack, almost solemnly; “another gun knocked out of business, and from what they say, the Turks can’t afford to lose many more these days, when it’s so hard to get them through from Austria and Germany.”

"That," said Retief, "should lend just the right note of solidarity to our little delegation." He hitched his chair closer. "Now, depending on what we run into, here's how we'll play it...."
