13. Historical and Philosophical Society of Ohio.—A society 
with the above designation, has been chartered in Ohio, by its Legis- 
lature. The names of its founders give good promise that it will 
not slumber, like too many of the societies in the older states; and . 
as the character of the West is eminently, to be up and doing, we 
look for fair fruits of knowledge and of positive utility from this new 
and hopeful institution. 
14, Corrections in Hassler’s Logarithmic Tables.* 
ewport, February 17, 1832. 
To Proressor Situiman.—Dear Sir—l take the liberty of pre- 
senting to your notice a few errors discovered in Hassler’s logarith- 
mic ides, as follows : 
In the tables of Numbers. 
The natural number 2940 is misprinted 3140 
“ iz3 
“cc es oe 3960 ce 74 5960 
“ 73 74 8640 “ec “ce 7640 
In the table of Natural Sines: 
Sine of 16° 42’ 30”, for 002874998, fe ee 4998. re 
of 9° 30’ 00”, and throughout the whole column to 9° 60’; for 
0,936, &c.; 0,935, &c.; 0,934, &e. Stead oy 986, &c.; 0, do” kes 
0,984, &c. 
These errors are all evident on a slight examination of the tables, 
and are therefore easily detected, but they serve to awaken a distrust 
of the accuracy of other parts of the work, in which errors would 
be less apparent and therefore more mischievou 
These tables of Mr. Hassler are so ae al for poe general 
form and arrangement, for their small volume, and their e 
usefulness even for the higher computations of ethan that the 
publication of them in our country may be considered as no small 
subject of gratification to our national pride 
Mr. Hassler professes, in the title page, to have presented to the 
world a set of logarithmic tables, “in which the errors of former 
tables are corrected.” But his reader of proofs has obviously left 
many of his own, to be corrected, itis earnestly hoped, in some future 
edition.—J. R. V. 
* From Mr. Hassler’s known candor, we doubt not he will be obliged by any 
patton ss: tending to render his valuable tables more free from typographical 
errors.—Ep.
