Fig. I.—Suction apparatus attached to ureteral catheter forremoving urine from speculum. gently, the bottle, which should hold a quart at least, servingonly as an air-chamber to equalize suction between strokes, andas a reservoir for waste urine. As soon as the ureter is entered,the suction-tube is to be slipped off the catheter and the specimencollected in the ordinary way.
