New broad- and narrow-band IR data are presented for Giclas 29 - 38, a white dwarf with a large excess of IR emission. The most dramatic aspect of the new data, strong emission at 10-micron wavelength, points toward the existence of particulate matter in orbit around G29 - 38. It is shown that such orbiting matter cannot lie in a single plane or a thick disk but might take the shape of a thin warped disk.
