Statistics of the Canary islands.  Tables.

July 22.

In the morning I renewed my magnetic observations and, having dined at the table d’hote, I passed the afternoon in calling upon several persons, and collecting such information regarding the group of islands as I could pick up.  Two statistical tables then given to me I have here inserted.

The first shows the extent of the seven larger islands and the average number of inhabitants in each.  On these numbers I think dependence may be placed, as they nearly agree, in the total, with that given by Tarrente in the Geografia Universal (1828) who makes it 196,517, being about 12,000 above the number given by Humboldt for the gross population at the end of the last century.

The second table gives the quantity of the most important products raised annually in each island.

Meteorological observations at Oratava and Santa Cruz.

To these I have added a short table showing the mean heat of every month at Tenerife, as deduced from a continued series of daily observations by Dr. Savignon and Mr. Richardson, at Laguna between the years 1811 and 1818, to which is annexed another of the quantity of rain which fell during some months of the years 1812 and 1813.

The two gentlemen who had made these observations having since died, I was not able to obtain any of the actual thermometrical observations, but to the son of Mr. Richardson I am obliged for having allowed me to copy the results contained in these tables.

Summary of observations made by Dr. Savignon* and Mr. Richardson, at Laguna.
