i oo Lessons in Nature Study. 



ally, and Principal Hulsart, of Dover, N. J., has some beau- 

 tiful specimens of skeletons done in this way. Care must 

 be taken, however, for if the potash is too strong the toes 

 and fingers come off. I should rather advise the use of 

 larger skeletons, as it gives a better exercise where the 

 scholars do the work entirely. 



Where a school has a skeleton of a dog, the subject of 

 bones may be taught almost as well as if it were the skele- 

 ton of a man instead. I have known pupils to become so 

 enthusiastic in the study of bones that on Saturdays a knot 

 of boys would gather in some grove or meadow to boil a 

 dead animal for next week's study. For many useful hints 

 in regard to work with bones, I am very greatly indebted to 

 Dr. E. W. Claypole of Buchtel College, Akron, O., whose 

 valuable contributions to science are well known.
