As a solitary exception to the general rule, the nations, after this gigantic blood-letting, did not experience the lethargy that follows from exhaustion, but the calm that the accession of strength produces. The explanation is easy. For about a hundred years the military selection committees had broken with the blind routine of the past and made it a practice to pick out carefully the strongest and best made among the young men, in order to exempt them from the burden of military service which had become purely mechanical, and to send to the depot all the weaklings who were good enough to fulfil the sorely diminished functions of the soldier and even of the non-commissioned officer. That was really a piece of intelligent selection; and the historian cannot conscientiously refuse gratefully to praise this innovation, thanks to which the incomparable beauty of the human race to-day has been gradually developed. In fact, when we now look through the glass cases of our museums of antiquities at those singular collections of caricatures which our ancestors used to call their photographic albums, we can confirm the vastness of the progress thus accomplished, if it is really true that we are actually descended from these dwarfs and scare-crows, as an otherwise trustworthy tradition attests. From this epoch dates the discovery of the last microbes, which had not yet been analysed by the neo-Pasteurian school. Once the cause of every disease was known, the remedy was not long in becoming known as well, and from that moment, a consumptive or rheumatic patient, or an invalid of any kind became as rare a phenomenon as a double-headed monster formerly was, or an honest publican. Ever since that epoch we have dropped the ridiculous employment of those inquiries about health with which the conversations of our ancestors were needlessly interlarded, such as "How are you?" or "How do you do?" Short-sightedness alone continued its lamentable progress, being stimulated by the extraordinary spread of journalism. There was not a woman or a child, who did not wear a _pince-nez_. This drawback, which besides was only momentary, was largely compensated for by the progress it caused in the optician's art.
