Thanks for pictures of Mars; speculates on the atmospheres of some planets.
Is pleased that JH likes his plates of Mars. Has a great collection of drawings of Mars but only a few of Venus. Hopes by the Spring to have the photoheliograph working. Has just completed his volume on the eclipse for 1860.
