Noyes devised hard-rubber probes, thelaroest of which were 4 mm. in diameter. Webers dilating probes,graduated and smooth, are also much used. After slitting the canaliculus the lumen of the lachrymal duct maybe reestablished by dilating with probes, either with or without incisionof the stricture or obstructing folds of tissue. The probe
