In the paper on the Mausoleum which I read before the Society on 14th June, 1893, and which has since been published in Archaeologia, I stated my intention to investigate two distinct questions relating to that celebrated building:
I. What appeared from the best literary and monumental evidence to have been its architectural form?
II. What was the most probable arrangement of its principal sculptures?
The first of these questions I have sufficiently dealt with in the paper referred to, subject to one correction, which I ask leave now to submit. Since the appearance of my scheme in Archaeologia, I have been led to adopt a slight modification of the architectural arrangement there suggested for the interior of the Pteron.
