and the least daily variation being nine-tenths of a degree. At Manila the greatest daily variation during the same period was 20.1° and the least was 3.9°. The mean daily variation for the three months at Manila was 12.6° and at Baguio was 7.87°, or 4.73° less than at Manila.

The bracing character of the atmosphere is attested by everyone who has visited the province of Benguet, and its purity is shown by the fact that fresh meat keeps without ice for from three to six days, according to the season. This last fact is of especial significance in connection with surgical operations and the treatment of wounds.

Our record shows that the relative humidity was slightly greater at Baguio during the months of August and September than at Manila, but during the month of October was 0.1 degree less. The rainfall was greater at Baguio during August and September, but was less during October.

In considering rainfall and humidity it should be remembered that an unusually large number of typhoons were felt in Northern Luzon during the period in question, and that one crossed the island just to the southward of Benguet. These storms are almost invariably accompanied by heavy and long-continued rain and by extreme moisture. The dry season has now begun at Baguio, and rainfall and humidity will probably be less there during the present month than at Manila. In this connection it may be worth while to insert a brief table, borrowed from the report of the Spanish commission, in which a comparison is made between the temperature, relative humidity, and rainfall for the year at Baguio and Manila:

There is nothing in the report of this Commission to show that their observations extended over a longer period than the sixty days of which we have the detailed record, but the Commission has been informed by Col. Cristobal de Arilar, a brother of Col. Rafael de Arilar, who was a member of this Spanish commission, that the latter gentleman remained at Baguio for nine months, taking full observations throughout this entire period. It is inferred that his results form the basis of the comparison made in this table.

It would seem that not only is the temperature much lower and more uniform at Baguio than at Manila, but the rainfall and relative humidity are materially less as well. Baguio is especially well situated to escape fogs, which are infrequent, considering the altitude, as
