The Garden Spiders: Building the Web 



has never been explained, our right side is 

 stronger and readier in its movements than 

 our left. The inequality is especially notice- 

 able in the two hands. Our language ex- 

 presses this supremacy of the favoured side in 

 the terms dexterity, adroitness and address, 

 all of which allude to the right hand. 



Is the animal, on its side, right-handed, 

 left-handed, or unbiased? We have had 

 opportunities of showing that the Cricket, the 

 Grasshopper and many others draw their bow, 

 which is on the right wing-case, over the 

 sounding apparatus, which is on the left wing- 

 case. They are right-handed. 



When you and I take an unpremeditated 

 turn, we spin round on our right heel. The 

 left side, the weaker, moves on the pivot of 

 die right, the stronger. In the same way, 

 nearlv all the Molluscs that have spiral shells 

 roll their coils from left to right Among the 

 numerous species in both land and water 

 fauna, only a very few are exceptional and 

 turn from right to left 



It would be interesting to try and work out 



to what e3ctent that part of the zoological 



kingdom which boasts a two-sided structure is 



divided into right-handed and left-handed
