¶5*662In Equity. On motion for- preliminary injunction.
¶6Macdonald & Macdonald, for complainant.
¶7Grafton E. McGill, for defendants.
¶10One of the elements of the claim in question is the series of slits in the lower portion of the bustle connected together at their edges. The defendants’ device does not have this series of slits. Whether the defendants’ method of gathering in the material is an equivalent for them is a question too doub'tful to be determined upon a motion for a preliminary injunction.
¶11The motion is denied.
