 and may then be bleached by exposure to direct sunlight for 

 two or three weeks, during which time they should be re-

 process also removes much of the offensive smell of freshly 

 macerated bones. Both these effects may, however, be more 

 quickly produced by steeping the bones in a clear solution of 

 bleaching powder, and afterwards washing them in running 

 water. 



Boiling the bones and then picking off the flesh yields 

 skeletons serving aU the purposes of the student, though not 

 so white as those obtained by maceration. 



The preparation of cartilaginous skeletons is described at 

 page 200.
