Regrets he cannot sign a memorial for correspondent’s father [Edward Truelove], which states an opinion on a life that is totally unknown to him.

Inquires about Porlieria: Do the leaves shut to check evaporation? Does it appear silver under water?

Explains how he thinks the pulvinus acts; wishes FD would investigate the point.
