Query: Families of surfaces lying in a null set   We generalise a result of Sawyer to show the following: For each y\in R^p and
w\in R^q let \Gamma(y,w) be a measurable d-dimensional surface in R^n. Under
conditions on the number of parameters and smoothness assumptions, there exists
a set of measure zero that includes a \Gamma(y,w) for every y.
