In consequence of the resignation of Dr. Turner a vacancy has recently occurred among the Medical Commissioners of Lunacy. It has been filled up by the appointment of Dr. Wilkes, the able and experienced medical superintendent of the Staffordshire county asylum. The selection of Dr. Wilkes for this honourable and important office is known to have been due to the noble Chairman of the Board, who has for many years been well acquainted with his steady and intelligent devotion to the duties of his position, and with his successful exertions in establishing the Coton Hill Asylum, for the insane of the higher and middle classes. The appointment of Dr. Wilkes is justly gratifying to the class of professional men to whom he belongs, indicating, as it does, the paramount importance attached by the highest authorities to an intimate practical acquaintance with the management of asylums and the treatment of the insane.
