John had a truly eclectic taste and another book that's known he had and supposedly enjoyed is
Forty-One Years In India
by Field Marshal Lord Roberts. How far from Huxley is that?
From the preface:
I send out this book in the earnest hope that the friendly anticipations
of those who advised me to write it may not be seriously disappointed;
and that those who care to read a plain, unvarnished tale of Indian life
and adventure, will bear in mind that the writer is a soldier, not a man
of letters, and will therefore forgive all faults of style or language.
