Discussion of and reply to ``Analysis of data obtained from an historic ash residue leaching investigation``

The author makes comments that should contribute to the content and appropriate use of this paper by Floyd Hasselriis. He points out that log-normally distributed data often plots as a straight line, especially if the data reflect purely random chance. The author also notes that the cycle of tube rapping appears to be 4 hr, not 8 hr, as Mr. Hasselriis incorrectly stated in the paper. He also points out that a proper procedure to use with log-normal data is to transform it to log form, calculate the mean and standard deviation, and convert them both back to the original form. This article also contains the original author`s reply to the comments.
