    Care of Instruments.—Scrupulous cleanliness is essential for the satisfactory use of the foregoing instruments. Especially is this the case regarding pipettes, and never under any circumstances should a pipette be put away dirty. Water is a satisfactory cleansing agent if iised at once, but as pipettes should be used dry it is preferable, after washing them out with water, to fill them with alcohol followed by ether. The short thick-walled pipettes of von Eleischl and Oliver's apparatus are readily cleaned by drawing a stout thread through them by means of a loop of fine wire which should be entered at the pointed end. A little clot readily forms at the extremity of the Thoma-Zeiss pipettes. If a pin or needle be used to remove this, the glass will almost certainly be chipped. A fine wire may be used carefully, but it is not an unknown accident for the wire to break, and then the last state of that pipette is worse than the first. An obstinate clot may sometimes be got rid off by digesting it out with pepsin and hydrochloric acid.
