 ing dissecting instruments :

In addition to this, each yroup of students should further 

 provide itself with the following instruments for use of the 

 group as a whole : 



2 Good dissecting scalpels. (There is only a very limited use for the knife, 

 hence not more than two need Vie provided. This may prevent many 

 poor dissections and bad hemorrhages) (Fig. 36) 



2 Aneurism needles (Figs. 37 and 38) 



2 Pairs of large blunt-pointed dissecting forceps (Fig. 39) 



1 Pair of smaller blunt-pointed dissecting forceps (Fig. 4' 1 ) 



3 Pairs of dissecting scissors, one large, two small (Fig. 41) 



2 Dissecting probes (Fig. 42) 



1 Large moderately sharp-pointed dissecting forceps to be used for inserting 

 cannulas (Fig. 43)
