§ 133. It will be seen from the foregoing list that the absolutely 

 necessary instruments for ordinary anatomical work are compara- 

 tively few and inexpensive. 



In purchasing instruments, the student should remember that 

 their value depends not upon their handles, their finish, or their 

 cost, hut upon the adaptation of their size, form andj temper to 

 the loorlc in view. 



On the other hand, while perfect instruments alone will not 

 insure a good dissection, they are generally more easy to use, and 

 more durable. Hence it is cheaper, in the end, to purchase the 

 best.

 " diagonal side cutting nippers," called nippers in this 

 work. Middle figure, blades of nippers seen from the 

 side. „ 



§ 134. Absorbent Cotton. — This is cot 

 ton freed from all impurities, and especially 

 from the oil which ordinary cotton retains 

 in small amount. It is therefore not 

 only cleaner, but capable of absorbing 

 water or alcohol instantly. On this account 

 Fig. io.-Stots's Nippers, -^ -^ ^^ ^^ preferred for the cushions which 



^ ' ' are made for freshly prepared brains, em- 



bryos, and other soft and delicate specimens to rest upon while 

 hardening. It should also be used for packing small or delicate 

 alcoholic specimens for transportation ; the ordinary cotton occupies 

 much more room at first than after it is thoroughly soaked, and a 

 space is thus left in which the specimen can be shaken to and fro. 

 AVhen ordinary cotton must be used for either of these purposes, it 

 should be first thoroughly soaTced. For dry packing, the ordinary 

 cotton will answer. 



§ 135. Arthrotome — Fig. 16. — This is a strong scalpel, two 

 edged for about 1 cm. from the point. The handle is steel, continu- 

 ous with the blade, and roughened like that of the anthropotomical, 

 "cartilage knife." The arthrotome should be used for the rougher
