A "bad Bore1 subfield" of a space X is an infinite countably g-generated u-subfield of Bore1 sets none of which (other than 8 and X) is open or closed. X has "very bad Bore1 subfields" if, for each countable ordinal CY, there is such a field of Bore1 sets none of which (other than 0 and X) is of Bor

## RBsumC. For each Bore1 set of reals of infinite rank A we obtain u "normal form" of A by finding a Bore1 set 62 such that A and 6! continuously reduce to each other. We do so by defining simple Bore1 operations which are homomorphic to the w, first Veblen ordinal operations of base (J, required
In nonstandard measure theory the standard part map is very useful to represent standard measures by Loeb measures. We give here a di erent method of representing measures using the concept of a -homomorphism. As an application a measure extension theorem is derived. Finally a nonstandard proof of a
