    The etiology of cutaneous diseases, as to be expected from the position of the integument in the organism, is many-sided and varied, and, owing to the relations ex- isting between it and the organism as a whole, fre- quently complex. External causes of disease, me- chanical and chemi(!al, of the most diverse character, as well as parasites, which not infrequently gain access to the skin, may have a markedly damaging action. The skin is further aflFected by many noxious influences which attack the entire organism, be they infectious diseases, the most pronounced clinical group of which (acute ex- anthemata) have an especially active effect on the integu- ment ; or be they intoxication by poisons which have developed or liave accumulated in the body itself, due to deficient elimination of the products of metabolism. The skin, therefore, presents a large number of sjpnpto- matiG diseases : The acute cutaneous exanthemata, syphilis, equinia, typhoid fever, cholera, uremia, etc. all usually have cutaneous manifestations. Diseases of single organs (heart, liver, kidneys, nervous affections) are not uncom- monly accompanied by phenomena on the external skin. Direct injurious influences to which the skin may be subjected give rise to the so-called idiopathic skin-diseases. These influences, whether they are of an infectious or chemicophysical, traumatic character, are the causes of many of the acute and chronic inflammatory cutaneous diseases. As cutaneous lesions are amenable to observation and to the sense of touch, they afford a very valuable subject— probably not as yet sufficiently ap]ireciated—for theoretic and scientiflc study, which not infrequently can be aided and confirmed by microscopic examination. Although it would be very interesting to enter into a discussion relating to this subject, and to consider the sequelcT and develo])- ment of granulation-tissue, formation of cicatrices, etc., we must, owing to lack of space, pass it by. The symptoms of skin-diseases arc divided into sub- jective and objective. To the former belong the various
