Woodward, H. B. On Geological Boundary-lines. Proc. Geol. Assoc. 

 vol. iv. no. 5, pp. 262-269. 



A review of the difficulties which attend any system of geological 

 classification, because of the variation in character of the beds and of 

 the fauna they contain. Divisions between formations are in many 

 cases less sharply marked than was formerly supposed. The conclusion 

 is, that lithological boundary-lines, such as can be mapped, are generally 

 best. Many divisions, palaeontologically important, cannot be traced 

 out on a map ; such boundaries are liable to change with fresh dis- 

 coveries ; but a lithological boundary always holds good. W. T.

Amongst the conclusions are : — 1. The shell heaps are the work of 

 man ; 2. They are composed of the remains of animals used as food ; 

 5. They contain human bones, broken up in a manner suggestive of 

 cannibal feasts ; 6. They contain fragments of extinct animals, as 

 mastodon, ox, &c. ; 7. They have undergone destructive changes by
