However, from Dr J W L Glaisher , who made me an intimate friend, who spent many an evening with me in heart to heard talks, who took me to meetings of the London Mathematical Society and the Royal Astronomical Society , and entertained me with gossip about scores of contemporary and earlier mathematicians, I gained more in a general way than from anyone else.
