NOTICE 



The Editor begs to refer his readers to the Intro- 

 ductory notice which precedes the only article of 

 which this number is composed. Possessed, almost 

 against all hope, of the power of publishing this valu- 

 able document, his wish has of course been to give it 

 as speedily as possible ; but he feels that as all his sub- 

 scribers are not equally interested in the subject of 

 which it treats, the occupation with it of one whole 

 number of the Journal which they support, would be 

 an unfair return for the substantial aid in matters of 

 general science which he has received from so many 

 among them. 



He has therefore resolved, (printing this year 13 in- 

 stead of 12 numbers of the Journal,) to offer the extra 

 number containing Capt. Herbert's Report to them 

 without any charge. |X| 



N. B. — The labour of emendation of the Report has 

 devolved entirely upon Mr. Piddington, Curator in 

 the Mineralogical and Geological Department to our 

 Society, to whose scientific knowledge, and critical 

 ingenuity, we are indebted for the elucidation of ma- 

 ny passages, which would otherwise have been hardly 

 intelligible, owing to the defective text.
