As it ispushed onward it is made to progress by a slight side-to-sicle motion,and it is of the utmost importance to bear in mind that the greatest gen-tleness must always be used. If any obstruction be felt, we are boundto withdraw the instrument partially or entirely, and attempt to manoeu-vre, not force, the point past it.
