340 Eighth Memoir on the £No. 137- 



me all data within their reach, or that of their friends, and I am much 

 indebted to them for their most ready assistance. I have as usual, 

 noted with every document the sources from whence it was obtained. 

 I commence, as in my former Memoirs, by giving the documents, 

 abbreviated as much as is consistent with clearness and accuracy of 

 detail ; and of these I have first chosen those farthest to the Eastward. 

 I shall then give comparative tables, and lastly, a general summary 

 and remarks, shewing upon what data, and according to what proba- 

 bilities, when data do not exist, the tracks and storm circles of the 

 charts are laid down. The general reader I trust, finds this part quite 

 readable, and the mariner and man of science will be able to judge 

 of the correctness of my inferences from the documents. I shall be 

 greatly obliged by their remarks and corrections from any part of the 

 world ; and if at times I may seem to have registered too many details, 

 it will be remembered that all details, and these given with fidelity, 

 are the essential elements for the successful investigation of every 

 complex physical problem, and most especially those relating to a new 

 branch of meteorology.
