The con- stant evaporation of benzine, camphor, creo- sote, and turpentine in the museum cases will usually keep them out ; specimens thoroughly impregnated with carbolic acid, arsenic, or corrosive sublimate are safe from their attacks. Their presence may be detected by the dust which they make falling beneath the specimens. The last is the A. muscBorum (Fabr.). DEKMODY, Thomas, an Irish poet, born at Ennis in 1775, died at Sydenham, near London, in 1802. His father was a schoolmaster, and is said to have employed him while only in his ninth year as his assistant in teaching Latin and Greek. He afterward ran away to Dublin, enlisted in the army, and served in the expe- dition to Holland under the earl of Moira, who promoted him to a second lieutenantcy ; but by his intemperate habits he lost the favor of his patron, and afterward lived some time in London, and died in extreme poverty. A small volume of poems written by him in his 13th year appeared in 1792. In 1793 he pub- lished a pamphlet on the French revolution, to which was appended a poem entitled " The Reform." During his residence in London he published two volumes of poems, in 1800 and 1802, and a separate poem, "The Battle of the Bards." His life, by J. G. Raymond, was published in 1805, and his works, under the title of "The Harp of Erin," in 1807, each in 2 vols. DERRICK. See CRANE. DKRRY. See LONDONDERRY. DERVISH, or Denrise, a Persian word equiva- lent to the Arabic fakir, signifying poor, used in Mohammedan countries to designate a re- ligious class corresponding in some respects to the monks of Christendom. There are many orders of dervishes, distinguished by peculiari- ties of faith, ceremony, and costume. They are gathered usually into communities, each in charge of a sheikh, and live together in monasteries, but many dwell in villages with their families. Their discipline professes to be very strict, its chief requirements being poverty, chastity, and humility. Mendicity is forbidden, except in the order of the Bektashis, and their monastic rules require them to support them- selves by the labor of their hands, though they are usually supplied by donations. With the exception of the order of the Mevlevis, all are allowed to marry and have dwellings outside of the convents, but must pass at least two nights of each week with their associates. Their religious rites consist of mortifications of the flesh, prayers, and dancing. Besides the fast of the Ramadan, they observe one weekly fast from morning till night, and they hold religious meetings on Tuesdays and Fri- days. They are frequently to be seen in the streets haranguing the multitude .and making a display of their wisdom and piety, but their
