been done and another pin inserted to keep it in place, as 

 shown in the diagram, the first pin may be removed ; repeat 

 the same operation on the other side. Other pins will be 

 required to keep the horns, etc., in place. In dealing with the 

 next specimen the strips will have to be turned back while it is 

 fixed into position, then proceed as before. An imaginary line 

 following the inner margin of the fore wings and passing through 

 the pin on the thorax is an excellent guide to uniformity in 



setting. The groove 

 will prevent the pin 

 leaning to either 

 side, but care should 

 be taken that it does 

 not incline either for- 

 wards or backwards. 

 The strip of tracing 

 cloth may be used 

 more than once, but the roughness of the pin holes should be 

 removed by drawing the strip across the back of a knife. 



The setting-boards most frequently used in this country have 

 sloping sides^ and are known as saddles (Fig. 18). Where 

 tracing cloth is used, the modus operandi is exactly 

 similar to that just described, but small pins will do 

 for pinning down the strips, as the saddles are made 

 of cork, or cork carpet, instead of wood. 



The following me- 

 thod of setting butter- 

 flies on the English 

 kind of " board " or 

 saddle is frequently 

 adopted. Select a suit- 

 able saddle, that is 

 one that has the groove wide enough to take the body, and 

 rather wider than the wings when expanded. A setting bristle
