purplish in color, varying in size from a pin's head up, 

 partially disappearing on pressure. This is the com

 to form larger lesions the condition 1- described as E. 

 tuberculatum. E. nodosum, dermatitis contusiformis .

 Idom more than a dozen) raised, rosy patches, 

 round or oval in the direction of the limb, from one 



half to tiller inches in diameter, suddenly develop 

 along both tibiae, and often along the ulnar side of the 

 forearms. They are exquisitely tender, tense and shin-

 is attended with no general symptoms, or with slight 

 pains in some of the joints, or with edema of the lee>. 

 E. roseola, a variety of /;'. hyperamicum : it consists 

 in the development of congestive patches of a delicate 

 rose-color, scarcely raised above the surface of the 

 skin, varying in size from a split-pea to a finger- 

 nail, and either diffused over the whole surface of the 

 body or in figured groups. It is common in young 

 children in association with digestive troubles. Its 

 different stages have been called Roseola infantilis, 

 aestivalis, autumnalis, annulata, but these terms are 

 not now generally used. E. scarlatiniforme, a 

 variety of E. hypercEtnicum ; it appears as a vivid, 

 punctiform eruption, sharply defined in places, attended 

 with high temperature, often seen after injuries or sur- 

 gical operations. It is followed by furfuraceous des- 

 quamation. E. scarlatiniforme desquamativum, 

 a more pronounced form of E. scarlatiniforme, with a 

 greater tendency to be diffuse instead of punctiform, 

 of longer duration, and with a great liability to recur at 

 certain seasons. The mucous membranes are often in- 

 volved and desquamation occurs in large flakes. E. 

 simplex, a variety of E. hyperamicum : characteri/rl 

 by a congestive redness of moderate intensity. It 

 appears as diffuse or circumscribed, variously-sized
