Abstract
The present article contains two new results: a closed form expression for the number of column-convex directed (ccd-) animals having a given bond perimeter, directed site perimeter and number of columns, as well as a certain logarithmic function, a part of which is the ccd-animals two perimeters & columns generating function. Finally, an attempt has been made to formulate, in a more immediate way, the original proof of Delest and Dulucq1 concerning the number of ccd-animals with a given area.
