NAPLES. 



BY JACOB B. BROWN.* 



The unit of arc of the 40th parallel is decimal seven -six -six. 



This compact statement is for those whose way of life has 

 brought them to an understanding of it. The little explana- 

 tion which follows is for whom it may concern. 



What is meant is that the degree of longitude on the equa- 

 tor is to the degree of longitude on the fortieth parallel as one 

 thousand is to seven hundred and sixty-six ; from which it 

 results that if one travel on the equator from the meridian of 

 Media, 75° west of Greenwich, to the meridian 14° east of 

 Greenwich, he will traverse 6148.12 statute miles; but if he 

 make the crossing on the fortieth parallel he will have only 

 .766 of this distance to go. 



Accordingly, if I could rub yonder lamp and summon 

 Aladdin's djinn or genie, I might bid him instantly transport 

 our building and all us with it due east 4709 miles and then 

 north sixty-nine miles and eight one-hundredths of a mile, 

 and we should find ourselves right in the midst of some of the 

 loveliest scenery in the whole world — namely, in the Bay of 

 Naples, just between Capri and Ischia. 



The time which is now here (say) eight o'clock in the 

 evening would be then and there one fifty-six of to-morrow 

 morning. If we were really there we would be glad enough
