on of between 3 and 4 eggs. February to April gives an error of prediction 

 1 between 4 and 5 eggs. Finally June to August gives an error of predic- 

 on of between 5 and 6 eggs. 



Considered in their relation to the average annual production these 

 ilues range from 0.13 to 3.39 percent. These results certainly show 

 :markable accuracy of prediction.
