46 TRANSACTIONS OF THE [nov. 11, 
ture which most marked him was the very heavy mass of hair 
falling over his forehead, which he would frequently stroke or 
toss back. Occasionally he would lighten up the monotony of 
anatomical description by a bit of humor. I remember one in- 
stance which was probably reminiscent of his famous tilt with 
Bishop Wilberforce at the meeting of the British Association 
in 1860. Huxley was describing the mammalian heart and had 
just distinguished between the tricuspid valve on the right side 
of the heart and the bicuspid valve on the left, which you know 
resembles a bishop’s mitre, and hence is known as the mitral 
valve. He said, “ It is not easy to recall on which side these 
respective valves are found, but I recommend this rule ; you can 
easily remember that the mitral is on the left, because a bishop 
is never known to be on the right.” 
Huxley was the father of modern laboratory instruction, but in 
1879 he was so intensely engrossed with his own researches that 
he very seldom came through the laboratory, which was ably 
directed by T. Jeffrey Parker, assisted by Howes and W. New- 
ton Parker, all of whom are now professors, Howes having suc- 
ceeded to Huxley’s chair. Each visit therefore inspired a cer- 
tain amount of terror, which was really unwarranted, for Huxley 
always spoke in the kindest tones to his students, although 
sometimes he could not resist making fun at their expense. 
There was an Irish student who sat in front of me, whose ana- 
tomical drawings in water color were certainly most remarkable 
productions. Huxley, in turning over his drawing-book, paused 
at a large blur under which was carefully inscribed ‘ sheeps’ 
liver” and smilingly said, “I am glad to know that is a liver; it 
reminds me as much of Cologne cathedralin a fog, as of anything 
I have ever seen before.” Fortunately the nationality of the 
student enabled him to fully appreciate the humor. 
The greatest event in the winter of 1879 was Darwin’s first 
and only visit to the laboratory. They came in together, Hux- 
ley leading slowly down the long narrow room, pointing out the 
especial methods of teaching which he had originated and which 
are now universally adopted in England and in this country. 
Darwin was instantly recognized by the class as he entered and 
sent a thrill of curiosity down the room, for no one present had 
ever seen him before. There was the widest possible contrast 
in the two faces. Darwin’s grayish-white hair and bushy eye- 
brows overshadowed the pair of deeply-set blue eyes, which 
seemed to image his wonderfully calm and deep vision of nature, 
and at the same time to emit benevolence. Huxley’s piercing 
black eyes and determined and resolute face were full of admi- 
ration, and at the same time protection of his older friend. He
