The following few particulars respecting the climate, diseases, &c. of Biscay, I obtained from a report drawn up by a few of the principal medical men of the province, at the request of the Royal College of Physicians in London. The medium heat of the thermometer in summer is from 19 to 21 of Reaumur, and in winter from 5 to 7. In summer, the thermometer scarcely ever rises above 26, and in winter, rarely falls below 0: changes in the temperature are sudden and extraordinary; the mercury having been known to rise and fall from 3° to 4° within a few minutes. The most prevalent winds are S. and N. W.; the S. the most constant in autumn, the N. W. in spring. The finest months are August, September, October, and sometimes November; the spring months are the most unsettled, rains being then almost as frequent as in winter. The summer months are the most salubrious; autumn less so; and winter and spring may be said to be unhealthy. The diseases most common in Biscay are cutaneous diseases; and catarrhs, especially pulmonary, which often terminate in pulmon. phthisis. Inflammations of the pleura, lungs, and bowels,--and rheumatism, are the most numerous after the class of pulmonary diseases; and of all these, the atmospheric changes may be considered the predisposing cause. The province of Biscay abounds in medicinal plants; but excepting a few simples used by the inhabitants, these do not enter into the Spanish pharmacopeia. Amongst these medicinal plants, are laurus nobilis, arbutus unedo, rabnus cartarticus, erica cantabrica, smilax aspera, humulus lupulus, tormentila erecta, poligala amara, digitalis purpurea, daphne laureola, gentiana luthea, anethenus nobilis. The number of deaths in Bilbao, calculated from the parochial register by an average of five years, amounts to one in forty-six yearly.
