12 KING: KADAPAH AND KARNÜL FORMATIONS. [PART I. - 
Nundaloor south of Cuddapah), whieh would lead me to believe that these 
secondary rocks might belong to the lower jurassic system." All the 
comment to be made on this evidence is that we have found no such 
remains, Some of the limestone beds do weather into very extra- 
ordinary coralloid shapes, but there are many reasons against these 
being organic. The fragment of the supposed Ammonite was “ very 
indistinet," while it is strange that no other fragment was found then, 
or ever has been since. Possibly the specimen in question may have been 
concretionary in its structure, and covered with dendritic crystallizations. 
The fossil may really be in existence, but until we know more about it, 
it is justifiable to doubt the structure of the object which was found. 
Dr. A. Schlagintweit also states that he had observed an  uncon- 
formity between his two groups of rocks; but unfortunately in the 
loeality of observation given by him, the superposition of the groups 
is the reverse of what he states, and there is an unconformity. Ina 
larger paper,* the same author again refers to these rocks, promulgating 
similar views; but hedoes not again refer to the supposed Ammonite 
among the other organie remains mentioned. 
In the season of 1858-59, Philip W. Wall, Esq.,f the then 
P. W. Wal Esq. Mineral Viewer of Madras, examined parts of the 
(1858-59). Cuddapah and Kurnool Districts with a view to the 
mineral resources of that part of the country: when he sent in 
reports to Government. He merely treats of the rocks with reference 
to his special objects, and considers them as clay stones, sandstones, 
and limestones. He does not enter mto the question of geological age.
