Amongst the many interesting monuments of India, the most remarkable, as well as the most ancient, are the cave-temples and topes of the Buddhists. The former have been made known by the pictorial illustrations of Fergusson; but the curious paintings which adorn the interior must be copied, and the numerous inscriptions must be deciphered, before the world will appreciate the full value of these works as illustrations of the religious belief and every-day life of the Indians of Alexander's time. Of the topes, none have yet been described, excepting the largest of the Sanchi group, near Bhilsa. An accurate plan and section of this building, with a short account of the various subjects represented in the sculptured bas-reliefs of the gateways, was published by my brother, Captain J. D. Cunningham, in the Journal of the Asiatic Society of Bengal. On his solicitation and earnest representation of the great value of these bas-reliefs, the Court of Directors were induced to employ Lieutenant Maisey to make drawings of the building and of its sculptured gateways. In January last I joined Lieutenant Maisey at Sánchi, and I am therefore able to speak positively of the value of his drawings, which cannot be surpassed for strict fidelity of outline and minute accuracy of detail. The groups of topes around Bhilsa will now be illustrated in a manner worthy of their value and importance.
