Opinions of the Press on the First and Second Editions. 



LfANCET, November 38, 1868. — " The work is f uU of usefulinf ormation 

 of every day utility to the practitioner." 



LANCET, July 16, 1870. — 'The Second Edition of this work shows 

 that the author has coiuinued to devote himself with zeal to the investigation 

 and treatment of a very interesting class of cases. We recommend the 

 work to the study of both Surgeons and Dentists." 



BRITISH JOURNAL OF DENTAL SCIENCE, August, 1870. 

 — "The Second Edition bears upon its pages the most satisfactory evidence 

 of the industry and leal with which he has followed up the study and prac- 

 tice of the specialty he has devoted himself to with so much success 



Altogether we must heartily congratulate Mr. Coles on this creditable com- 

 pletion of a work which cannot but redound to his credit, wherever it is 

 known."

 Opinion of the Press. 

 AMERICAN DENTAL REGISTER, November, 1874— "The

BRITISH JOURNAL OF DENTAL SCIENCE, August, 1876. 



—" We cordially welcome this useful little book Of great value 



to those preparing for the Dental Diploma We hope there will 



soon be a Second Edition needed." 



THE DOCTOR, September, 1876.— " Carefully arranged and very 

 complete. Indeed they seem to try to take in rather more than sufficient for 



Dental students We have no other fault to find with this note-book, 



which appears a model^of what such a work should be." 



THE MOUTH AND TEETH DURING PREG- 

 NANCY. Reprinted by permission from the Transactions of the 

 Odontological Society. Pp.31. Price is. 6d. London: Wyman and 

 Sons, Great Queen Street. 



Opinion of the Press. 

 THE BRITISH MEDICAL JOURNAL.— "The author has 

 evidently paid considerable attention to the subject, and gives many useful 

 hints as to the management and relief of the distressing toothache and 



neuralgia complicating pregnancy The remarks on treatment are 



practical, and will repay perusal. The practitioner will do well to 



carry out the suggestions offered by the author. 



NEW VIEWS IN ASTRONOMY. 



Mr. Harris will be glad to receive the names of gentlemen willing to 

 devote the time necessary to make themselves acquainted with the reasa 

 and ez'ieience supporting the arguments in each of the twelve important cas_ 

 included in the " new views," in order that he may arrange explanatoir 

 lectures expressly for the purpase of bringing the several subjects succc 

 sively under their consideration in a satisfactory manner. 



The lectures will be given, in the first instance, at the Town Hall, Kilbur 

 where the models and diagrams are now on view, as soon as a sulificiei 

 number of persons to constitute an audience have sent in their names anid 

 expressed their intention of attending. 



It is, of cjurse, desirable that all those attending should have at leas 

 some elementary knowledge of physical science, and it is hoped that man] 

 of the professional, practical, and learned students of natural science 

 make it their business to attend the lectures. 



In consequence of the somewhat excessive fear on the part of scienti 

 journalists of offending the prejudices and atiioiir propre of (so-calle 

 orthodox science, it has been as yet impracticable to bring any of the 

 extremely important subjects under the notice and consideration of tho9 

 who ought now by thorough knowledge of their merits to be in a position to 

 appreciate and pass judgment upon them. 



'Ihe subjects of the proposed lectures are as follows: — "Gravitation and 

 Centrifugal Force," "The Theory of Cometary Orbits," "Aberration of 

 Light," " The Law of Gravitation, and the Relative Orbital Planes of 

 Planetary Revolution," "Theory of the Double Tide, and the supposed 

 Tidal Effect of the Sun's Gravitatlve Influence," " The Pendulum as a 

 Measurer of Terrestrial Gravitation," " Velocity-theory and Undulatory- 

 theory of Light." 



Cards of invitation to the lectures with particulars will be sent as soon as 

 the number is sufFicient to enable arrangements to be made. Mr. HARRIS'S 

 address is CLIFTON HOUSE, KILBURN SQUARE. 



The astronomical working models and diagrams illustratine the '• new 

 views" and "old theories," will continue on view at the Town Hall, 

 Station Road, Kilburn, on Mondays, Wednesdays, and Fridays from 3 to 5 

 o'clock, and from 8 to 9 o'clock p. m. 



Admission by Cards only. 



Gentlemen interested in the subject will be welcome on presenting their 



own cards.
