The problem is that you are reversing the string a few times. The following will do: (defun base8 (n) (let ((t8 (truncate n 8)) (m8 (mod n 8))) (if (= t8 0) (list m8) (append (base8 t8) (list m8))))) EDIT Here's a solution without append, using a helper function.
So, the average weight for a healthy, human kidney is 0.26-0.30 pounds. (approx.) The average weight for a healthy, human kidney is 120-140 grams. 1 pound= 453.59237 grams.

The normal size of the kidney is the human fist size. There are some factors that can affect the abnormal growth in size. One of the factors is the growth or development of cysts in the organ. When cysts start to develop, the kidney can grow as big as a football. In addition, the weight can reach 38 pounds.
