The Spanish-American universities had the advantage of being closely in touch with the European universities, and as a consequence had taken their traditions direct from them. Papal university charters, as a rule, required explicitly that there should be three years of university work before medicine or other graduate work might be taken up, and then four years of medicine before the degree of doctor would be granted. Even after this, according to the Italian laws of the thirteenth and fourteenth centuries, the practice of medicine must not be begun by the graduate until he had spent a year in practice with an experienced physician. This is the year of hospital work that we are now trying to introduce into the medical schools as a requirement and which is taken, but voluntarily, by most of those who are seriously interested in their professional studies. The preliminary requirements, that is, such formal academic preparation for the study of medicine as makes it possible for a young man to take up the subject and properly benefit by it, have only become obligatory by law in very recent years here in America, and that to a very limited degree. The letter written to the Municipal Council of his native city, Seville, by Dr. Chanca, who accompanied Columbus on his second expedition, shows the thoroughly scientific interest and the acute powers of observation of the Spanish physicians of this time. This is unquestionably the first written document about the flora, the fauna, the ethnology and the anthropology of America. Dr. Fernandez de Ybarra published in the _Journal_ of the American Medical Association, September 29, 1906, some abstracts from this letter which show that these expressions are justified by its contents and are not mere enthusiastic terms for rather commonplace observations. Chanca described in detail woods of various kinds, fruit, spices, plants such as cotton, the birds and animals, and above all the customs, appearance and mode of living of the inhabitants. He gives in detail their slave-making and cannibalistic tendencies. There was nothing that escaped Chanca's observation. He found turpentine, tar, nutmegs, ginger, aloes, though he noted that the aloes were not the same kind as those in Spain (Barbadoes aloes are still {285} considered inferior), cinnamon, cloves, mastic and many other things. He notes the food of the inhabitants, their mode of working, the absence of iron, yet the well-made implements, the presence of gold in many places, describes the climate of the country and gives important details with regard to its meteorology.
