The base line varies with the volume of the effusion andmay reach 6 or 10 cm. in length. The triangle is usually larger in right- thanin left-sided effusions. The respiratory murmur, vocal resonance, andvocal fremitus are enfeebled over this area of dulness. The phenomenonoccurs alike in hydrothorax and in serofibrinous and purulent effus
