Martin (1992: 327):
At group and word rank instantial relations are constructed through apposition:
[4:2:9.r.] With the smaller breeds of dog such as Corgis, all the Toy-breeds, Dachshunds and this type of thing we — as our turn comes,[5:34] I met Ben, a friend of mine from Toronto.[5:35] Ben stroked (i.e. lobbed) the ball over Flo's head.
The only instantial lexical cohesive relation here is in [5:34] — Ben–friend — since this is the only one specific to a single text. The other two lexical cohesive relations, both hyponymy, are each 'a general fact of English' (Hasan 1985: 81).
