CHAPTER VII.
On Climate and Disease.—Panama, Guayaquil, Peru, and Chile.
For those who propose to cross the Isthmus of Panama, or visit the shores of the Pacific, it may be interesting to be made in some degree acquainted with the influence of particular climates, and the sort of illness which they are most likely to experience at the principal commercial ports, particularly to the south of the line. On this account the author now offers some general hints on these subjects, having it in view to publish as a separate treatise a practical account of the diseases of Peru, described as they occur at different altitudes, in the diversified climate of that country.
The seasons at Panama are divided into wet and dry: the rainy season begins towards the latter end of May, and continues till November; and from November to June, or the latter end of May, is the dry season. At Panama, agues, fevers, bilious and gastric complaints are common in the wet season; but the yellow fever, or “Vomito negro,” very rarely has been known to pass the mountain barriers which separate the Atlantic from the Pacific. At Cruces the traveller may enjoy a better and safer climate, during the wet and unhealthy months, (when the thermometer never, perhaps, falls below 90°,) than either at Panama or Chagres.
To the north of the Isthmus, along the shores of Central America and Mexico, as far at least as the northern tropic, the climate is considered “malsano,” or exceedingly unhealthy; a fact well known to those who trade with Realejo, San Blas, and Mazatlan, where very dangerous remittent fevers prevail.
To the southward of the Isthmus on the shores of Colombia, in about 2° south latitude, we find the port and city of Guayaquil, of well-known commercial importance. Here, the climate is considered unhealthy during the wet season, when the air is sultry and oppressive; but in the dry season Guayaquil is not reckoned particularly sickly. The rain commences in light showers in December, is very heavy in February, and dwindles away in April. From May to December is the dry season.
The wet season, being the hottest, would naturally be considered as summer; but here, as in other places of seasonal or periodical rains, the wet season is called “invierno,” or winter, and the dry season “verano,” or summer; yet the latter is cooler than the former, and allows one to wear warmer clothing than would be agreeable in the rainy months.
