Summary:

Having been assured by ES that the government might receive a request for more money for magnetic observations, JH retreats from his earlier position [see JH's 1844-7-17], and is willing to accept the possibility of a magnetic conference, which JH does not want to lead in any way. JH believes his scientific life is almost over and he has much to do.
