With many thanks to Guy St. Amant and Herman Tull for the immediate replies (and pdfs)! Apparently, the volume is available on google books in the US.

All my very best,

Dear all,

Do any of you happen to have a pdf of Albrecht Weber's 1871 edition of the Taittirīya Saṃhitā Books I-IV (Indische Studien vol. 11)? As far as I can see, archive.org only has the second (1872) volume. I know the Titus version of the text is Weber's, but I'd ideally like to check the original.

Many thanks,
