Acknowledges receipt of JH's Cape Results by Holland Society of Sciences.

Received [WB's] packet. JH has influenza, will read manuscript after recovery.

Wonderingly admires WH's quaternions. Lady Herschel has not yet thanked Eliza Hamilton (WH's sister) for the poetry because of serious illness. Except for influenza, would wish WH's son to visit for Easter. Mentions 'political extravaganzas.'

Thanks Hooker for letter of recommendation, which has helped them obtain passports. Will try to collect “interesting specimens for the Kew museum.”
