Summary:

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.
