Describes the funeral of James MacCullagh; mystified why he committed suicide.
The equatorial on the Dublin Observatory dome needs improvement. In the last fifty-two months, WH has seen three new planets: Neptune, Iris, and Flora.
WH notes that quaternions derive some interesting results in problems with three moving bodies.
Thanks WH for 'plan' of [asteroid] Iris. Family is happy to have WH's son (JH's son William's friend) with them for holidays. Recounts their playful and adventurous activities.
