Sending account of the magnetic disturbances of 24 September 1847.
More continual subtractions to resolve Bernoulli's 17th number. Error in official value given in Encyclopaedia Metropolitana. Also working on Bernoulli's 18th number.
Regarding his own method of calculating the perturbations of the comets. Expense of computation is high for an individual and a mention by JH would bring support for his scheme. Would like to explain his method at an ordinary meeting in January. Every branch of science is facilitated by tables and those he suggests seem most desirable.
Will certainly help him regarding the Cape dome. Gives details of his mounting. Sends a copy of his observations.
