3, jBarometric Tables for tJie use of Engineers, Geologists, and Scienti- 



Jic Travellers. By William Galbraith, A.M., <S:c. Ediii. 

 Stirling &^ Kenney, and A. Adie, Optician. 183§. 



Mr Galbraith, already so well known as a cultivator of ma- 

 thematical and physical science, has done an acceptable ser- 

 vice to geologists, and others, by the publication of these 

 useful tables. They were computed by the author with the 

 greatest care, and the results examined by means of differences, 

 before putting to press. In reading the proofs, the same care 

 was bestowed. They were then cast, and proofs from the ste- 

 reotype plates were next read, with the same precautions as be- 

 fore ; and, in the whole, two errors only were discovered and 

 corrected. Table I. contains numbers in English feet, cor- 

 responding to the height of the barometer in inches, tenths, and 

 hundredths, with proportional parts to thousands, from 1 to 9. 

 Table II. contains the corrections for the expansions of mercury, 

 depending on the difference of the temperatures of the mercury 

 in the barometer tubes, indicated by the attached thermometers. 

 Table III. contains the corrections depending on the mean tem- 

 perature of the air and the approximate height. Table IV. em- 

 braces the corrections for the latitude a, and the corrected height 

 H'. Table V. will be found useful for converting French metres 

 into English feet, when a comparison is made with heights pre- 

 viously determined, either trigonometrically or barometrically.

That the taste for popular natural history is on the increase, 

 is shewn by the numerous light and gay works on this subject, 

 daily issuing from the press. Enterprising publishers and artists, 

 aware of the general desire among all classes of readers for this 

 kind of information, have at times given to their readers correct 

 information, illustrated by judiciously selected and well executed 

 engravings. The most beautiful of these cheap books on natural 

 history we have met with, is the Naturalist's Library, of which al- 

 ready a good many thousand copies of each volume have been sold.
