J.W. Laidlay examined fragments of the sandstone slab that had been donated to the Asiatic Society of Bengal by Colonel Butterworth and Lieutenant-Colonel James Low, strewing finely-powdered animal charcoal over the surface of the stones and sweeping it gently with a feather so as to fill up all the depressions; in this way "the very slightest of which was thus rendered remarkably distinct by the powerful contrast of colour. By this means, and by studying the characters in different lights", Laidlay was able to make drawings of the inscriptions on three fragments. According to Laidlay, the fragment shown in the top drawing seemed to have been from the upper part of the inscription, but was omitted in Prinsep's lithograph as effaced. He could not identify the other two fragments with any portion of the lithograph.
