Note.— It may excite surprise, that none of the " decided lines of fracture" described by Dr Hibbert in his paper on the 

 Burdiehouse Limestone, as traversing- the Mid-Lothian coal-field, are laid down on the Map accompanying this paper, or are 

 specified in the above Table. The truth is, I have not been able to discover any one of these alleged lines of*' fracture. I regret 

 this the more, on account of their being all described by Dr Hibbert as running in directions varying little from SW., and dif- 

 ferent therefore in this respect from the great proportion of the fractures existing in the district. 



I may add, with reference to the mode in which the information regarding the Slips was obtained, that it was, in most in- 

 stances, derived either from plans of the coal-workings, or from the under-ground overseers, as mentioned in the Table. Where 

 there is no authority given in the Table, the statements rest on my own observation. 



Since the first part of my Memoir was read and printed, I have acquired information regarding several slips of which I was 

 not then aware. These have been added to the Table. This addition creates a slight discrepancy between the Table and the 

 Memoir, — though, so far from invalidating the statements made in the text, it strongly confirms them.
