Dysaesthesia

(From difficulty, and

to feel or perceive). A dullness of sensation, or faulty sense. Under this term, Dr. Cullen forms his first order of his fourth class locales; though in the enumeration of the species he has not adhered closely to the definition. Diseases of this order are synonymous with hallucinationes, according to this author, and are considered as complaints whose principal symptom is a depraved or erroneous imagination. He defines them, the senses depraved or destroyed from some defect or fault of the external organs. Privativi are reduced to this head.

Dysalthes

(From difficulty, and to cure). Difficult of cure.

Dysanagogos

(From and to tubdue). An epithet for tough viscid matter, which is with difficulty expectorated.

Dyscatapotia

(From and to drink). A difficulty of swallowing liquids, which Dr. Mead thinks a more proper term than that used for canine madness, viz. hydrophobia, as it is more particularly descriptive of the affection under which the unhappy patients labour; but, in reality, they dread water from the difficulty of swallowing it.

Dyscine Sia

(From and to move). Difficulty of motion, from faulty or defective organs: also termed intemperies. This is the third order of Dr. Cul-len's class locales-defined, motions impeded or depraved from the fault of the organs.

Dyscracy. An ill temperament or habit of the blood and humours, as in the jaundice and scurvy.
