ARE DOGS " COLOUR-BLIND "P

[To THE EDITOR or THE " BrEcraTos."] SIR,—Your correspondent," W. H. O'Shea," has found several dogs " colour-blind." If black is a colour, I can give several instances in which a black retriever dog of mine was certainly vaot "colour-blind." He had the greatest antipathy to sweeps and coalheavers, and would fly at them if not fastened up or 'carefully watched. He would even bark at a passing hearse ! In all other respects, he was the best-tempered dog in the world, .and I can only imagine that when very young he must have teen ill-used by either a sweep or a coalheaver.—I am, Sir, &c., P.R.T.
