be weaker with them, than with the European laborer; but those which are exerted in the chase, and those faculties which are employed in the tracing an enemy or a wild beast, in contriving ambuscades for him, and in carrying them through their execution, are much stronger than with us, because they are more exercised. I believe the Indian, then, to be, in body and mind, equal to the white man. I have supposed the black man, in his present state, might not be so; but it would be hazardous to affirm, that, equally cultivated for a few generations, he would not become so. 3. As to the inferiority of the other animals of America, without more facts, I can add nothing to what I have said in my Notes. As to the theory of Monsieur de Buffon, that heat is friendly, and moisture adverse to the production of large animals, I am lately furnished with a fact by Dr. Franklin, which proves the air of London and of Paris to be more humid than that of Philadelphia, and so creates a suspicion that the opinion of the superior humidity of America may, perhaps, have been too hastily adopted. And, supposing that fact admitted, I think the physical reasonings urged to show, that in a moist country animals must be small, and that in a hot one they must be large, are not built on the basis of experiment. These questions, however, cannot be decided, ultimately, at this day. More facts must be collected, and more time flow off, before the world will be ripe for decision. In the meantime, doubt is wisdom. I have been fully sensible of the anxieties of your situation, and that your attentions were wholly consecrated, where alone they were wholly due, to the succor of friendship and worth. However much I prize your society, I wait with patience the moment when I can have it without taking what is due to another. In the meantime, I am solaced with the hope of possessing your friendship, and that it is not ungrateful to you to receive assurances of that with which I have the honor to be, dear Sir, Your most obedient, and most humble servant. TO THE GOVERNOR OF MARYLAND. PARIS, June 16, 1785.
