26 INTRODUCTION 



CLOTHING. 



The better methods of preserving the material for dissection 

 prevalent nowadays have removed some of the unpleasant feat- 

 ures of the occupation. It is not possible, however, to avoid all 

 odor or all contamination, and the student should, therefore, go 

 to the dissecting-room clad in a manner which will permit him 

 to work freely and without constant worry lest his clothing come 

 into contact with the material. Hence it is necessary to have an 

 old coat to be kept for use in the dissecting-room only, and it is 

 preferable to change the whole suit on entering and on leaving 

 the room. As a roomful of men garbed in old coats is not a 

 pleasing spectacle, it is the custom in modern anatomical labora- 

 tories to wear white cotton gowns over all. The student should, 

 therefore, provide himself with three such gowns, so that he may 

 always have the soiled ones laundered while the clean one is 

 being worn. Gowns other than white should be avoided, as 

 should the various oil-cloth sleeves and aprons formerly so much 

 used. No inconsiderable part of the depressing influences of 

 the old-time dissecting-room consisted of the dirty floors, the 

 untidy tables, the tobacco-smoke, the spittoons, the oil-cloth 

 sleeves and aprons, and the multicolored or checked gowns. 



Dissection is a serious task, requiring much energy and en- 

 durance. Under the best conditions the student tires all too 

 quickly. It is important, therefore, that the sanitary conditions 

 of the room be the best possible, that as comfortable a position 

 as practicable be assumed in dissecting, that the dress be one 

 which while externally uniform throughout the room will permit 

 of the . greatest freedom in work, and that all depressing in- 

 fluences be as far as possible removed. 



DRAWING IN GBOSS ANATOMY. 



The student should not try to draw all that he sees, but only 

 so much as is important in the stage represented. He should 

 limit the contents of each picture to what can be shown clearly, 

 and try to avoid unimportant detail. 



The drawing is to be made large enough to show clearly all 

 that it contains. In general, it should be as large as the size of 

 the drawing-paper will permit, allowing for the legend. It is 

 well to make the drawing on a definite scale, and to record on it 

 the proportion which the size of the picture bears to the natural 

 size, using a fraction to express this, e.g., Vs, V 2 , Vi, Vi> or 

 whatever the scale is.
