 necessary information may be obtained." — London and Edin. Phil. Magazine. 



" I hardly expected, from the title, to have found such complete directions for marine surveying, a 

 branch of the subject that has been too little attended to, — especially as to the proper observations on the 

 rise and fall of the tides. I should like to see the book in every midshipman's berth in the Royal Navy."

 known to the public." — Sir David Brewster. 



" It appears to me that you have grappled successfully with your subject, and produced a 

 useful and valuable volume, and one which, I have no doubt, will have a great circulation, if only 

 for the number of curious and interesting facts described and collected in it." — Sir John Herschel, 

 Bart. 



" We borrow these refreshing passages from the Introduction to Meteorology of Dr Thomson — 

 a work of a full and well-assorted mind — to which we shall often refer in the department now engaging 

 our attention." — Dublin University Magazine.

 ments. It is a great storehouse of facts scientifically and carefully arranged." — The Economist.

" Written by an experienced and most intelligent agriculturist, not upon hearsay evidence or second- 

 hand data, but upon careful observation and examination of the nature and capabilities of the soil. The 

 opinions the author has formed are of very great value, and his conclusions most satisfactory to all 

 interested in the regeneration of Ireland, by means of properly-directed industry, supported by skill and 

 capital." — Bell's Life.

 that introduced them. Wherever ornament makes any part of the object of the cultivator, the Planter's 

 Guide will be found to be his best director ; pointing out, as it does, the means of executing with success 

 the designs that taste may have conceived for the embellishment of the landscape. It teaches not merely 

 the art of planting, but the principles upon which the art is founded ; and supplies us not merely with 

 rules but with reasons." — Edinburgh Review.
