_ The triangular channel K was of the form given in Plate 
III., fig. 3, the breadth at the surface of the water being 
12 inches, the depth 4 inches to 0. It.was observed that during 
the whole of the experiments the wave was long and low on the 
deep side ; short and pointed, and considerably higher and con- 
tinually breaking, on the shallow side, so as to leave behind a 
long train of secondary waves.
