The classical training so strictly required of natives who enter these high-schools is not so rigidly inquired into in the case of foreigners,--though in this respect the regulations differ in various states. In Prussia and generally, the passport is all-sufficient; but in Würtemberg, a diploma or some certificate of former studies must be exhibited before admission. The officers of some of the universities, as Tübingen, for instance, are very particular in enforcing all the rules, inquiring of the applicant, whatever be his age or nationality, whether he has a written permission from his parents to study abroad and in their university, whether he has the money necessary to pay the debts he may contract, and such other minute questions as will strike an American especially as particularly impertinent. The precaution is carried so far, that, when no positive information is given as to means of subsistence, the letter of credit must be delivered into the hands of the beadle as security. Yet such little incidents are but slight annoyances at most, which a little good-humor and desire to conform to the habits and ways of doing of the country will remove. He who goes abroad always ready to bristle up against what does not exactly conform to his preconceived ideas of propriety, measuring and weighing all things with his own national weights and measures, will be continually making himself disagreeable and unhappy, and in the end profit little by his absence from home. The conclusion of the training-system in the gymnasia usually occurs before the nineteenth or twentieth year. With the reception of the certificate of maturity the youth may be said to have donned the virile toga. He enjoys during his university years a degree of liberty such as he never enjoyed before, never will enjoy again when his student-days are over. Having taken out his matriculation-papers, and given the _Handschlag_ (taken the oath) to obey the laws of the land and the statutes of the university, he has become a student,--a _Fox_, as the freshman is styled,--he chooses his own career, his own professors, hears the lectures he pleases, attends or omits as he pleases, leads the life of a god for a triennium or a quadrennium, fights his duels, drinks his beer, sings his club-and-corps songs.--But of student-life more in due time.--There is no check, no constraint whatever, during the whole time the studies last. At the expiration of three or four, sometimes even five years, an examination takes place before the degree of Doctor can be conferred,--not a severe one by any means, confined as it is to the special branch to which the candidate wishes to devote himself. In the Medical and Law Departments it is more serious than in the Philosophical. This examination is followed by a public discussion in presence of the dean and professors of the faculty, held in Latin, on some thesis that has been treated and printed in the same language by the candidate.
