You will also remember that we injected fluids into several of the larger branches of the coronary vein, and that these fluids issued all into the cavity of the left auricle by a large opening (Jig. 2, d.), which proved to be the mouth of the coronary vein, while none of it was seen en- tering into the right. The subject was a male, and rather advanced in years.

As the case was uncommon, we have had drawings taken both of the right and the left auricle, which, as well as the preparation itself, I now shew you. A broad piece of whalebone is introduced into the mouth of the vein, and is distinctly seen in the preparation, and imitated in the drawing (Jig- 2.).
