Containing to Seven Places of Decimals, natural Numbers, answering to all
Logarithms from 00001 to 99999; and an improved Table of Gauss's
Logarithms, by which may be found the Logarithm to the sum or difference of
Two Quantities where Logarithms are given: preceded by an Introduction,
containing also the History of Logarithms, their Construction, and the
various Improvements made therein since their invention. By HERSCHELL E.
FILIPOWSKI.
The publisher, having purchased the copyright and stereotype places of
these Tables, (published a few months ago at 2l. 2s.,) is enabled to offer
a corrected edition at the above reduced price.
_Testimonial of Augustus de Morgan, Esq._
"I have examined the proofs of Mr. Filipowski's Table of Anti-Logarithms,
and of Gauss's Logarithms, and also the plan of his proposed table of
Annuities for three lives, constructed from the Carlisle Table.
"The table of Anti-Logarithms is, I think, all that could be wished, in
extent, in structure, and in typography. For its extent it is unique among
modern Tables. Of accuracy I cannot speak, of course; but this being
supposed, I have no hesitation in recommending it without qualification.
"The form in which Gauss's Tables are arranged will be a matter of opinion.
I can only say that Mr. Filipowski's Table is used with ease, as I have
found upon trial; and that its extent, as compared with other tables, and
particularly with other FIVE-FIGURE tables, of the same kind, will
recommend it. I desire to confine myself to testifying to the facility with
which this table can be used; comparison with other forms, as to RELATIVE
facility, being out of the question on so short a trial.
"On the table of Annuities for three lives, there is hardly occasion to say
anything. All who are conversant with Life Contingencies are well aware how
much it is wanted.
"A. DE MORGAN."
