THE LUNERAL. 557 



nesday, showing the day for 419 to be Wednesday, and 

 for 420 it will be Thursday. We may now place 20 under 

 Thursday in the top row, and by finding Thursday in the left- 

 hand column, and using the lower group of units, we find 

 429 to be Tuesday, and 430 is Wednesday ; 30 goes under 

 Wednesday. In the same way we find 440 to be Monday, 

 450 Sunday, 460 Friday, 470 Thursday, 480 Tuesday, and 

 490 Monday. Some of the tens being Leap Year, and some 

 not, two groups of units are necessary ; but as all the centurial 

 years are Leap year, one group of tens is sufficient. The 

 only difference the alteration in the calendar made to the 

 days of the week was that instead of repeating themselves 

 every 700 years they do so every 400 ; and now that we have 

 the tens and the units arranged, we can easily read the 

 Luneral, starting from J 753 to test its accuracy, until we 

 arrive at the current year, and on till we arrive at 2153 and" 

 discover the circulation every 400 years. With the tens and 

 units in their places, the proof of the Luneral is in the 

 reading, for it takes a second of time to read a year, and 

 half an hour to go from the year to the present time ; as 

 the Luneral goes on for ever, we may continue reading as 

 long as we choose ! Or we may reason as follows : — As we 

 went back in the calendar we found a day of the week was 

 gained in every centurial year ; it follows that, as we advance 

 in the calendar, a day of the week is lost : so if the day for 

 1800 be Wednesday, for 1900 it would be Tuesday ; but as 

 1800 is not Leap Year, owing to the alteration, two days are 

 lost; therefore Monday is the day for 1900, and Saturday 

 for 2000. 2000 being Leap Year, only one day is lost, 

 therefore Friday is the day for 2100, Wednesday for 2200, 

 and so on.* 



We now come to the months, and will represent the seven 

 days of the week by seven letters of the alphabet. B now 

 represents the day for any year in which 1 st January falls on 

 a Sunday ; it v/ill also serve to represent the first Sunday in 

 January of the same year, so we place January opposite B in 

 the last side of the square, and read in the year B the first 

 Sunday in January falls on 1st. In Table A and under 

 column 6, 1st January falls on Saturday, and the first Sunday 

 in January falls on the 2nd. As V represents Saturday, this 

 letter, two places removed from January, reads correctly as 

 follows : — In the year V, or any year in which 1st January
