Barao de Capanema wrote to the presidents of all the BraziHan provinces for 

 information regarding earthquakes; after three years, no replies having been 

 received, the request was renewed by the Instituto Historico e Geographico, and 

 to these later inquiries six of the presidents replied, but apparently most of them 

 gave negative results. The paper contains reference to some phenomena that 

 may or may not indicate earthquakes. Capanema's list includes the two men- 

 tioned by Ayres de Cazal in Matto Grosso, and some of those given later and a 

 little more at length by Thomaz Pompeo de Souza for Ceara. He adds one for 

 Espirito Santo, and one for Rio Grande do Sul. The paper is occupied chiefly 

 with a discussion of earthquakes in general. 



3. Thomaz Pompeo de Souza BrasiL—Y^nsdAo estatistico da pro- 

 vincia do Ceara, I, 51 (Ceara), 1863. Under the head of "earth- 

 quakes" the author states that a few slight shocks have been fek 

 in the valley of the Rio Jaguaribe and at Granja, north of Fortaleza. 

 The important footnote is here given at length : 



"The following are the earthquakes of which I have been informed: On 

 August 8, 1807, throughout the entire valley of the Jaguaribe extending north- 

 ward to Fortaleza (180 kilometers), southward to Ico (300 kilometers), and east- 

 ward to Mossoro and the Serra do Martins in the province of Rio Grande do 

 Norte. 



"On May 31, 1810, at Granja, and again in the years 1846, 1852, and 1855. 



"In 1824 the earth opened making a wide crack from the base of the Serra 

 de S. Pedro to Jardim, a distance of 5 leagues, with a width of about one palm and 

 of unknown depth. 



"On December 2, 1852, at Aracaty."

The date and intensity of an earthquake felt at Pernambuco October 28, 

 181 1, are fixed by three letters written by observers in reply to inquiries made by 

 the Emperor Dom Pedro II. One observer states that the people were filled 

 with terror; another reports that the shock was so violent that things were nearly 

 thrown from tables, and a fountain erected in the patio of one of the churches was 

 overthrown. This suggests an intensity of about VI of the Rossi-Forel scale.

This is a long article devoted to geology, but at p. 281 the following mention 

 is made of two earthquakes:
