Canis Minor, the Little Dog, in Astronomy, a constellation of the northern hemisphere; called also by the Greeks Procyon, and by the Latins Antecanis and Canicula. The stars in the constellation Canis Minor, are in Ptolemy's catalogue, 2; in Tycho's 5; in Hevelius's, 13; and in the British catalogue, 14.

Canisius, Henry, a native of Nimeguen, and one of the most learned men of his time, was professor of canon law at Ingoldstadt; and wrote a great number of books; the principal of which are, 1. Summa Juris Canonici. 2. Antiquae Lectiones, a very valuable work. He died in 1609.
