Scheme of a Table for all Time. By Capt. R. Short redk, Assisla?it 

 Surveyor General. 



I enclose for publication, if you approve, in your Journal, a Per- 

 petual Time Table, which I constructed sometime ago ; by the help of 

 which may be found in less than half a minute, the week-day of any 

 date for thousands of years, past or future. 



Besides the directions given on the back, little more seems necessary 

 to render intelligible the method of using it. The Table consists of 

 three concentric circular cards, each having seven divisions corres- 

 ponding to the days of the week. On the outer are written, from left 

 to right, on three circles, the odd years of a century. On the second 

 card are written the full centuries, of New Style on the outer, and of 

 Old Style on the middle circle ; the order of these being from right to 

 left. Within are the days of the week from left to right. The third 

 card has the days of the month from left to right, and within 

 these, the twelve months in a peculiar order, each following month being 

 as many divisions to the left as the days in the preceding month 

 exceed 28. 



In using the Table, the first thing is to adjust the second card with 

 its proper century to the zero on the outer card ; thus for 1841 New 

 Style, the full century being 18, the division containing the N. S. 18 

 on the second card, is to be brought opposite that division on the outer 

 card which contains the double zero (00). This being done, the middle 

 card will require no change till the year 1900, when the centurial divi- 

 sion containing 19 (N. S.) is to be brought opposite the (00) division.
