Congratulates Smith on acquisition of the Linnaean collections, "undoubtedly the most valuable that could come into the hands of any naturalist". Presumes Smith will part with some of the collection and retain the herbarium; comments on disposal of rare books, harnessing the value in the manuscripts, and selling off the shell, fish, and insect collections on account of their fragility. Discussed the purchase with Smith's father, who is happy with it and Smith's prudence that it will not interfere with his studies. Warns against Russian roubles.
