that many details of structure in man could not be explained through natural selection, I invented sexual selection; I gave, however, a tolerably clear sketch of this principle in the first edition of the 'Origin of Species,' and I there stated that it was applicable to man. This subject of sexual selection has been treated at full length in the present work, simply because an opportunity was here first afforded me. I have been struck with the likeness of many of the half-favourable criticisms

Indeed,Einstein arrived at his theory through a train of thought of greatoriginality. Let me try to restate it in concise terms. THE EARTH AS A MOVING CAR Everyone knows that a person may be sitting in any kind of a vehiclewithout noticing its progress, so long as

for I should soon have got over my disgust; and the practice would have been invaluable for all my future work. This has been an irremediable evil, as well as my incapacity to draw. I also attended regularly the clinical wards in the hospital. Some of the cases distressed me a good deal, and I still have vivid pictures before me of some of them; but I was not so foolish as to allow this to lessen my attendance. I cannot understand why this part of my medical course did not interest me in a

After a brief inspection by a young man with the appearance of a secretary, I was told that I was expected, and admitted into a small room opening out of the hall. Thence, after a few moments' waiting, I was led into a much larger room. The walls were lined all round with bookcases, barred and numbered, filled with volumes forming part of the philosopher's great library. I had not long to wait. A door

t instigated by love of knowledge]In fact, the history of physical science teaches (and we cannot too carefully take the lesson to heart) that the practical advantages, attainable through its agency, never have been, and never will be, sufficiently attractive to men inspired by the inborn genius of the interpreter of nature, to give them courage to undergo the toils and make the sacrifices which that calling requires from its votaries. That which stirs their pulses is the love of knowledge and

ts had been seeking a panacea for all the ills to which flesh is heir, indeed for something which would enable men even to defy Death, and the subtle new spirit was eagerly proclaimed as the long-looked-for cure-all, if not the very aqua vitæ itself. Physicians introduced it to their patients, and were lavish in their praises of its curative powers. The following is quoted from the writings of Theoricus, a prominent German of the sixteenth century, as an example of medical opinion of alcohol in

these transformations all the other physical properties of a substance save weight are likely to change, the inquiry arises, Does the weight also change? Much careful experimenting has shown that it does not. The weight of the products formed in any change in matter always equals the weight of the substances undergoing change.~Law of conservation of matter.~ The important truth just stated is frequently referred to as the law of conservation of matter, and this law may be briefly stated thus:
