"As to Medicine, I have read up most of the text-books prescribed here, so that I am really very well up on the subject, and Jim Shepherd says I would make a capital doctor. I went along with him to the 'Dissecting-room,' 'Anatomical Museum,' 'Infirmary,' and 'Incurable Hospital,' and he did his best to sicken me (as you remember befell me three years ago), but I was all right, so he says I am now 'hardened'! It was very interesting seeing all the poor ill folk, and it was a real pleasure to speak to them, and joke with them, and leave them cheery." In Germany it is evident even from his meagre notebooks that he thoroughly enjoyed life, and entered into it with his usual zest and brightness. But everything was subordinated to study. He made himself master of the language, and did his best to profit from the lectures he attended. His good parents were naturally alarmed at the effects which German practice and thought (more dreaded then, perhaps, than now) might have upon their son. He warns them against uncharitableness. "There is nothing so difficult," he says, "as to convey a true and fair picture of the religious state of a people.

"For instance, he has been defending the doctrine of the Trinity, the personality of the Holy Ghost, the Divinity of Christ, and eternal punishment. He is very practical and thorough." His attachment to Dorner grew as is witnessed by the following letter:—
