Are you dealing with hyperaemia, inflammation, luemorrhage, hyper- tro])hy, atrophy, an infiltration or a new growth ? If the pathology be clearly grasped, a great stride is made towards differential diagnosis, as it leads at once to the exclusion of alternative diseases. In the case of crusted lesions, always remove the crust to see what is underneath. It is very necessary to have a good light when viewing cutaneous afliections; and daylight is best.
