With this the wall is sawn through imtil the depth arrived at is equal to what is indi- cated by a previous examination of the thickness of the crust as viewed from the solar surface. Here Colonel Smith says : ' I strongly advise everyone to use a metal gauge (a thin piece of material) to introduce into the incision made by the saw, and run it up and down to ascertain whether the wall is properly divided throughout. The depth to which this should be done we know from the previous measurements of our gauge on the crust.'. Fig. 144.—Smith's Side-bone Saw (Early Pattern). Should the saw be of a pattern in which the set of its teeth makes only a narrow incision,* it should, while opera- ting, be kept well oiled, and should be withdrawn every few seconds in order that the horn-dust lying in its teeth may be examined. If this is getting slightly bloodstained, we know, of course, that the sensitive structures are reached, and the incision has been carried far enough. In so judging the depth of the incision, however, care must be taken to see that the top of the coronary cushion is not injured with the saw, for if this is done the blood trickling into the depth of the incision will tinge the horn-dust, and give the false impression that the incision is sufficiently deep. If the operator has had no previous experience of the use of the saw in this operation, he must also be careful to * That is Smith's older pattern. The newer pattern (Fig. 145) has the teeth so set as to make an incision wide enougli to be looked into. In this case the depth arrived at is to be judged by the appearance of the bottom of the Please note
