LXXXVII. On Errors in the Nautical Almanac. 
June 1, 1814. 
Sirs,— Baume much struck with the notices of the numerous 
and remarkable errors in the Nautical Almanac for the year 
1816, mentioned in your last number (193), on immediately 
turning to the work, I found that all those errors, though 
really existing, are not to be found in the several months in the 
body of the work, but are all contained in what may be consi- 
dered the 2d page after the preface, titled Principal Articles, 
&c. where are found not only all the said errors mentioned by 
Criticus, but many others also, which he has passed over in 
his haste; for I find that all the twelve Ember days, mentioned 
in the said page of the Almanac, are every one of them 
wrong. Thus, 
What are said to be Feb. 19, 21, 22, ought tobe March 6, 8, 9; 
and instead of May 20, 22, 23, ought tobe June 5, ii 8; 
and instead of Sept. 16, 18, 19, ought to be Sept. 18, 20, 21 é 
and instead of Dec. 16, 18, 19, ought to be Dec. 18, 20, 21. 
It then occurred that possibly similar errors might exist in 
some of the other year’s Almanacs ; and accordingly, in turning 
over that for 1815, many errors soon appeared. Thus, in the 
column of Holidays, &c. in the month of May, page 49, there 
are two, VIZ. 
Oxford Term ends on the 11th, instead of the 13th day; 
and Oxford Term legins onthe 24th, instead of the 20th. 
Again, in the like column of June, page 61, we find 
Trinity Term begins on the 3d, which was on May 24, 
Trinity Term ends on the 2\st, instead of the 14th. 
On the 5th day, in 8 days 2d return, for in 15 days 3d return. 
On the 12th day, for 15 days 3d ret. read 3 weeks 4th return. 
Again, in July, page 73, in the like column, all the numbers 
of the Sundays are wrong, being all 1 too many; so that instead 
of 6th, 7th, 8th, 9th, and 10th, should be the oth, 6th, 7th, 
8th, and 9th. 
The same mistake happens in the month of August, where 
the llth, }2th, 13th, 14th Sundays should be the 10th, 11th, 
12th, 13th. 
Under the article Other Phenomena, in the last column of 
the first page of every month, many things, particularly the 
Occultations, are omitted, which it was usual formerly to insert. 
There are several other smaller omissions in different places, be- 
sides one of more remarkable import entirely omitted; viz. the 
Transit of the planet Mercury over the Sun, which will take 
place on the 12th of November that year. 
Such discoveries as these naturally create a suspicion as to.
