That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved-who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";-for him to make a difficulty of the matter is inexcusable.

The terms "black box" and "white box" are convenient and figurative expressions of not very well determined usage. I shall understand by a black box a piece of apparatus, such as four-terminal networks with two input and two output terminals, which performs a definite operation on the present and past of the input potential, but for which we do not necessarily have any information of the structure by which this operation is performed. On the other hand, a white box will be similar network in which we have built in the relation between input and output potentials in accordance with a definite structural plan for securing a previously determined input-output relation.

Early entry is appropriate when the following general circumstances hold:
- Image and reputation of the firm are important to the buyer, and the firm can develop an enhanced reputation by being a pioneer.
- Early entry can initiate the learning process in a business in which the learning curve is important, experience is difficult to imitate, and it will not be nullified by successive technological generations.
- Customer loyalty will be great, so that benefits will accrue to the firm that sells to the customer first.
- Absolute cost advantages can be gained by early commitment to supplies of raw materials, distribution channels, and so on.

There is no pure visualization in the sense of a priori philosophies; every visualization is determined by previous sense perceptions, and any separation into perceptual space and space of visualization is not permissible, since the specifically visual elements of the imagination are derived from perceptual space. What led to the mistaken conception of pure visualization was rather an improper interpretation of the normative function... an essential element of all visual representations. Indeed, all arguments which have been introduced for the distinction of perceptual space and space of visualization are base on this normative component of the imagination.

You must handle [the House of Lords] a little more firmly, and the time has come for unflinching and resolute action. For my part, I would not remain a member of a Liberal Cabinet one hour unless I knew that the Cabinet had determined not to hold office after the next General Election unless full powers are accorded to it which would enable it to place on the Statute Book of the realm a measure which will ensure that the House of Commons in future can carry, not merely Tory Bills, as it does now, but Liberal and progressive measures in the course of a single Parliament either with or without the sanction of the House of Lords.

I have presented the periodic table as a kind of travel guide to an imaginary country, of which the elements are the various regions. This kingdom has a geography: the elements lie in particular juxtaposition to one another, and they are used to produce goods, much as a prairie produces wheat and a lake produces fish. It also has a history. Indeed, it has three kinds of history: the elements were discovered much as the lands of the world were discovered; the kingdom was mapped, just as the world was mapped, and the relative positions of the elements came to take on a great significance; and the elements have their own cosmic history, which can be traced back to the stars.
