Males are more frequently affected with aneurism than females. According to the statements of some surgeons of the largest experience, more than seven-eighths of all cases occur in men. This greater liability of the male sex is due to the relative frequency in that sex of fatty and earthy degenerations of the coats of the arteries, and not, as has been well pointed out by Prof. Gross, to the difference in the occupation and habits of the two sexes. In the words of the professor of surgery at the Jefferson Medical College, " the opinion which ascribes the greater frequency of spontaneous aneurism in males than in females to their more laborious occupation, their more intemperate habits, and their greater exposure to all kinds of disease, is entirely untenable, and, therefore, unworthy of confidence. Women, it is true, are not sailors, carpenters, blacksmiths, or hod-carriers, but in many parts of the world they are tillers of the soil, and engaged in almost every variety of pursuit calculated to rupture the arterial tissues if they were in a serious state of disease, such as we so often meet with in the other sex."
