COMETS and their Tails, 



AND 



THE GEGENSCHEIN LIGHT. 



By FREDERICK Q. SHAW, F.G.S., 



Assoc.M.Inst.C.E., etc., 

 AUTHOR OF "FISCAL FACTS AND FICTIONS." 



Opinions of the Press. 



London Quarterly Review. "Mr. Shaw's ingenious theory cannot fail to 

 interest anyone who has a taste for such subjects. The romance of science is 

 well represented in this acute and most interesting little book." 



Nature. " The work as a whole is brief; its tone is very modest." 



Sheffield Telegraph, ''Mr. Shaw's theory is plausible, ingenious and inter- 

 esting, evincing close reasoning on the part of its author." 



Glasgow Herald. "Accurate in its general facts, sound in its authorities, and 

 cautious in its tone." 



Morning Post. " Mr. Shaw in this admirably printed little book propounds a 

 theory which is certainly worth consideration. It is put forward in a very read- 

 able and even lively manner, and is forced by several carefully-prepared plates." 



Dublin Irish Times. " With full command of the most advanced astronomical 

 learning, Mr. Frederick G. Shaw, F.G.S., a traveller of wide experience and a 

 deep scientific thinker, now advances a novel theory as to cometic tails, and 

 as to that mysterious light commonly known as the Gegenschein. Singularly 

 interesting study ... it will, there can be no doubt, engage the earnest attention 

 of all astronome'rs, and give rise to fruitful discussion." ' 



Scotsman. " Of unusual interest to readers who stud}- astronomy. Simply 

 enough and lucidly enough expounded in the book. Original, ingenious, and 

 suggestive, the book deserves the attention of every one interested in its subject." 



African Review. "Revealing a fund of knowledge in astronomical and 

 meteorological science." 



LORD RAYLISIGH. "With regard to your theory of the Gegeuschein, I do not 

 remember seeing the lens-like action of the earth's atmosphere noticed before." 



Critic. " But, as I have known Mr. Fred. G. Shaw for some years, and have 

 recognized his ability as a writer and a scientist more than once in my columns, 

 his late departure as an author of a new theory on the most abstruse astronomical 

 problems merits some attention. His ingenious solution of the great geological 

 puzzle of the Witwatersrand conglomerates is still fresh in the minds of scientific 

 men; and in turning to astral problems, as he has done in his work 'Comets and 

 their Tails, etc.,' he exhibits the same logical deductive thought shown in his 

 pseudo-morphic theory as to the formation, etc., of the said conglomerates. It is 

 certain that he has scored a success in his solution of the Gegenschein light. 

 I heartilv commend this book to mv readers."
