In 1728, after he had recovered from the effects of the severe malady with which he had been attacked, he visited his parents. His mother was extremely grieved at seeing him occupy his whole time in collecting plants and glueing them upon paper, as she plainly perceived that there was now no hope of his ever becoming a preacher. Dr Rothmann, who frequently saw him, pointed out the superior advantages which students possessed at Upsal, where there were "the learned Roberg, the great Rudbeck," a splendid library, and a fine botanic garden. He also named many poor students who had received assistance from the government, and had become able practitioners. The young naturalist readily believed the representations of one who had taken so much interest in him, and resolved to follow his advice. At setting out, his father gave him a sum of money equivalent to about L8 sterling; informing him at the same time that he could do no more for him. With this slender provision Charles proceeded to the University of Upsal, where, although he had no reason to expect a kind reception, he hoped at least to obtain more ample means of scientific research. The professors, however, were not such as they had been represented, nor did any of them show the smallest attention to the poor student. Before he had been a year there his pecuniary resources failed; so that he was in a manner cast upon the charity of his companions, among whom he was glad to accept an occasional meal, and even a worn-out article of clothing. The old shoes which they gave him, he was often obliged to mend with pasteboard and birch-bark before he could render them tolerably efficient. He now found reason to sigh for the comfortable home which he had left at Lund; but to it he could not return, for as he had quitted his benefactor Stobaeus abruptly, and without so much as apprizing him of his intentions, he justly dreaded his displeasure. Aware that he could not obtain aid from his father, destitute of friends, and even of the hope of procuring a livelihood by the exertion of his talents, he was reduced to the extremity of indigence: yet he despaired not; nature had at all times charms to support his spirits; he struggled with his fate and conquered. On an important occasion which occurred many years after, he publicly returned thanks to Providence for having supported him amid these privations:--"I thank thee, Almighty God," said he, "that in the course of my life, amidst the heavy pressure of poverty, and in all my other trials, thou hast been always present to me with thine omnipotent aid."
