In this paper we present two generalizations of the results on the intersection numbers of tdesigns: the first is related to a result of Ray-Chaudhuri and Wilson (Osaka J. Math. 12 (1975) 737-744) and the second to that of Mendelsohn (in:

## Abstract The following results for proper quasi‐symmetric designs with non‐zero intersection numbers __x__,__y__ and λ > 1 are proved. Let __D__ be a quasi‐symmetric design with __z__ = __y__β€‰βˆ’β€‰__x__ and __v__ β‰₯ 2__k__. If __x__ β‰₯ 1 + __z__ + __z__^3^ then λ < __x__ + 1 + __z__ + __z__^3^. Let
