If it is desired to keep the sections in the serial order in which they were cut they may be transferred one by one into small phials, a single section to a phial.

If it is desired to keep the sections in the serial order in which they were cut they may be transferred one by one into small phials, a single section to a phial. More elaborate microtomes have devices for carrying the section knife, or for holding the knife stationary while the object is made to vibrate back and forth against it, and in this way sec- tions can be cut with increased rapidity and accuracy. In some forms there is an automatic feed which can be set to any desired thickness of section. One of the simpler forms of microtomes with a knife carrier is seen in Fig. 143, where the principle of its operation will quickly be recognized. As there shown the knife should be set at an angle to make a long sliding cut in all cases excepting where material imbedded in paraffin is to be sectioned. In the latter event the knife is to be set square across at right angles to the direction of its motion, so that the sections are chopped instead of whittled off. In this.
