CHAP. 1.[ PREVIOUS OBSERVERS. 9 
After these writers, Captain Newbold again appears in the field as 
an accurate observer and prolific writer for many years. It is needless 
to refer to all his papers in detail (a list of which is appended*), there 
being quite sufficient matterin his * Summaries of the Geology of 
Southern India" to show the conclusions at which he arrived and how 
well he worked. It may be said with truth, that each paper is about 
the most clear and careful deseription of whatever it was intended to 
illustrate that has been given by any of the explorers of Southern India. 
Whatever errors he has fallen into are almost all due to his not having 
been able to make a thorough investigation of the rocks. His gravest 
error is that which is common to all the writers on the same subjects, 
viz., that he places the limestones below the quartzites, yet even here 
he shows that glimmerings of the true state of the case were breaking 
in on him continually, though they were again and again obseured by 
his not having been able to draw a true distinction between the different 
bands of quartzite and limestone occurring in both the Kapapan and 
KARNÜL formations. In fact, it may almost be affirmed of Captain
