1. Theo must have responded critically to the passage about sowing wheat in the right soil in letter 400 (and hence about Theo’s ‘true’ destiny), accusing Vincent of mistakenly believing that he could judge the situation in Paris. These opening sentences are the reply to this.
2. Van Gogh originally wrote ‘waterhoozen’ (waterspouts), and changed it to ‘crisissen’ (crises).
3. Theo supported several members of the family and Marie.
4. Van Gogh’s ‘Beware’ both in this context and in letter 406 has to be read as the English word (cf. also ‘Make up your mind’, l. 270). In the present letter he wrote it in very large letters.
