Gottfried Jacob Jaenisch starts his letter by saying that he cannot but seize this opportunity to send Linnaeus a few lines and express his great appreciation. He recently read Linnaeus’s letter to Johann Peter Kohl. All the splendid physical and medical observations in this letter impressed him. The life of a physician, who must lead a practical life and constantly assist at the bedside, is a far cry from the lives of scientists who can work undisturbed and create things that bring blessings to everybody and honour and glory to themselves. Jaenisch is not at all envious of these men, but prays that they may have long lives, that they may be amply rewarded and be judged always by just critics. He is happy that Linnaeus has found such critics in Leiden and congratulates him on the honour he has received in Harderwijk. How wonders how Johann Kramer is, and what Claes Sohlberg is working on. Jaenisch would be extremely grateful if Linnaeus would assist Kramer in his studies. He humbly asks Linnaeus to keep him informed about his research, of which the success is his only prayer. If Linnaeus should need his assistance, Jaenisch will be more than willing to help.
