Could a colleague who has access to the first volumes of the Jahrbücher für wissenschaftliche Kritik let me know if they have a review of Bopp's Ausführliches Lehrgebäude der Sanskrita-Sprache, and, if they do, who wrote it?  Such a review should have appeared in the volumes of 1828 or 1829.  The run of JWK in the Penn library begins in 1832, which is also when the electronic run by the Hathi Trust begins, and our otherwise wonderful system of interlibrary loan does not work for journals. 

Also, if anyone has a copy of Peter von Bohlen's review of Friedrich Rosen's Radices Sanscritae in JWK 1828, coll. 65–85, I would be grateful for a copy as well.    

With thanks and best wishes,
