_Theses._--Perhaps it may assist your correspondent "M." (No. 25. p.
401.) to be informed that the University of Göttingen is particularly
rich in "_Theses_" (termed _Disputationes et Dissertationes_), to which
there is a large room entirely devoted in the library of that
university; together with the transactions of learned bodies. A special
librarian is attached to this department, which is much consulted. A
Catalogue was begun to be published of this collection, so far as
respects the _Memoirs_ contained in the various transactions, in 1801,
by J.D. Reuss; and 16 vols. in 4to. had appeared up to 1821; after
which, I believe, the publication has been suspended. Of Catalogues of
Theses, I think the following work is in good esteem:--_Dissert. Acad.
Upsal. habitæ sub Præsid. C.P. Thunberg_, 3 tom. 8vo. Götting.
1799-1801. The second part of vol. ii. in the _Catalogus Bibliothecæ
Thottiauæ_ (7 vol. 8vo. Fauniæ, 1789-1795.) contains a catalogue, which
it might be well to consult, of dissertations under the name of the
president or head of the institution or college where they were
delivered, than under the writer's name. At least, in a _collective_
sense the former method is adopted, as in the following instance:
Schultens, (Alb.) _Sylloge Dissertationem Philologico-Eregeticarum,
adiversis Auctoribus Editarum, sub Præsidio A. Schultens, etc._, 2 tom.:
although, if the author should happen to be distinguished for his other
productions, _all_ that he wrote is anxiously sought out, and placed
under his own name.
