In particular I cannot seem to find these: D.S. Rajan, "Differentiation and Integration of the Combinatorial Species of Joyal", PhD Thesis, Dept. of Mathematics, SUNY at Buffalo. Yeong-Nan Yeh, "On the Combinatorial Species of Joyal", PhD Thesis, Dept. of Mathematics, SUNY at Buffalo. Electronic versions would be extremely welcome. If only paper versions exist (but you have a copy!), contact me by email and we can work out an appropriate method of duplication+transmission. Jacques
