The second day opened with a discussion o£ the classification 
of the Cambrian- Silurian. Mr. Hicks remarked that as a 
known impartial pupil of Salter on one side, he was equally at- 
tached to the Cambridge school and the Geological survey. He 
had hence, sought for the truth in an independent manner. 
With Salter the upper Cambrian is the equivalent of the pro- 
mordial of Barrande, and its terms are inferior to the rest of 
the Silurian, so that the primordial fauna is at the summit of 
the Cambrian. Mr. Hicks has recognized since that beds in- 
ferior to these are equally fossiliferous, and the summit of the 
Cambrian is the Tremadoc, characterized by the fauna of 
Olenus. Above the Tremadoc begins a new fauna with grap- 
tolites and Asaphas. This is the Lower Silurian. The Cam- 
brian school, on the contrary, establishing the Cambrian on 
stratigraphic characters, extends this system up to the Lland- 
overy, where there is a discordance. Such is the difficulty, and 
the term Ordoviciau, of Mr. Lap worth, comprising the Lower 
Silurian oP one and the upper Cambrian of the other, is rec- 
ommended as a term of conciliation involving the whole. 
Mr. Marr rejected stratigraphic limitations, and would hold
