The BAKER of THURSO: Life of Robert 



DICK, Geologist and Botanist. By SAMUEL SMILES, LL.D., 

 Author o£ " Lives of the Engineers." 



"It was my gratification to meet a remarkable man in Thurso, named 

 Robert Dick, a baker by trade. I am prcud to call him my distmguished 

 friend. Here is a man who is earning his daily bread by hard work, who is 

 obliged to read and study by night, and yet who is able to instruct the 

 Director-General cf the Geographical Society." — Sir Roderick Mur- 



CHISON. 



" Men of Dick's type are rare ; their e.xample is too precious to be lost : 

 but they are themselves the last to recognise their own value. Dr. Smiles 

 has done a good work in rescuing from obscurity a life so lofty in its ex- 

 ample." — Quarterly Review.

THOMAS EDWARD, Scotch Naturalist. By SAMUEL SMILES, 

 LL.D., Author cf " Self-Help," &c. 



" This homely and simple story is a record of success in unsuccess — of 

 fame unmingled with any sordid advantage— of work absolutely disinterested 

 and done ' for nought,' as all the noblest work has been done. It is the 

 story of a poor shoemaker who is a famous natural philosopher without 

 ceasing to mske shoes, or attaining in his old age to any seat more easy than 

 that of his familiar bench." — Blackwood' s Edifibnrgh Magazine.

NEW VIEWS IN ASTRONOMY. 



By JOHN HARRIS. 



Having decided on exhibiting (at the Town Hall, 

 Kilburn) some carefully prepared Working Models 

 and Diagrams illustrating certain of the subjects be- 

 longing to Astronomical Science, Mr. Harris desires to 

 briefly specify the object and purpose of the Exhibition. 



The " New Views " (twelve in number) are not of 

 the character of sudden notions on the subjects to 

 which they apply. It is believed that each of them is 

 quite " new " to the educated public : even to .Astro- 

 nomers and other men of Science. It is quite certain 

 that, in each case of the twelve, the subject brought 

 under consideration is of the highest interest and im- 

 portance. Collectively they constitute the result of a 

 searching and very careful examination of the most 

 important theories of what is at the present time 

 considered the orthodox doctrine of Physico-As- 

 tronomical Science : an examination carried on per- 

 sistently for a number of years. In each case, v/ithout 

 exception, the argument has been repeatedly subjected 

 to revision and re-examination, and they are now 

 brought prominently forward, not only with confidence, 

 but with assured certainty, on the part of Mr. Harris, 

 that Fact and the Rules of Inductive Philosophy will, 

 on the most rigid scientific scrutiny, be found to 

 justify the "New Views" and condemn the "Old 

 Theories " in each and every instance. 



It may be well here to state distinctly that no one 

 has any pecuniary interest whatever in the matter. 

 The object and purpose of this mode of proceeding 

 is to communicate knowledge — presumably of very 

 great interest and importance to the public — in a short 

 time, which otherwise, partly from opposing prejudice, ■ 

 and partly from the defetisive attitude which professional 

 men of Science feel bound to assume on such questions, 

 would probably take a long time to make known, 



Mr. Harris purposes to devote as much time as prac-j 

 ticable to explaining the models and diagrams to visitorsi 

 at the stated times of exhibition ; and, should it appeaf 

 desirable, will give explanatory lectures on the severs 

 subjects successively. 



The Models, etc., will be on exhibition from 3 to 

 o'clock P.M., and from 8 to 9 o'clock p.m., on Mondays^ 

 Wednesdays, and Fridays of each week, commencing on 

 Monday the 7th April, and probably continuing through- 

 out April. 



The Explanatory Lectures, if given ((which for the pre- 

 sent is not decided), will probably be in the following\ 

 order : — 



Monday April ^ith.- 



Wednesday „ 15 /"/;.- 

 Saturday ,, 1 8tli.-
