 augeat, totiusque human! generis utilitatibus serviat. Illud quoque nobis 

 pergratum est recordari, quod Gulielmus ille Allen, qui primus fuit Societatis 

 Pharmaceuticae anno MDCCCXLI praeses, et ipse Societatis Regalis sodalis 

 fuit, quodque Societas Regalis semper et sua opera et aliis incitandis magno 

 fuit adiumento Societati nostrae, per hos septuaginta annos id agenti ut 

 artium chemicae et pharmaceuticae scientia apud Britannos amplificaretur. 

 Datum Londinii, die III mensis Iulii, MCMXII^pro Societate Pharmaceutica 

 Magnae Britanniae.

PHYSICAL SOCIETY, LONDON 



To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. Many 

 illustrious names have been inscribed on the roll of the Royal Society during 

 the 250 years which have elapsed since its foundation ; but none have added 

 a greater lustre to the fame of the Society and to the glory of their country 

 than those of the men who devoted themselves to the study of Physics. 

 Newton firmly planted the Tree of Science, Young, Joule, Faraday, Maxwell, 

 Stokes, and Lord Kelvin have spread its branches in many directions. May 

 we, therefore, a young Society specially devoted to the study of Physics pay 

 our warm tribute of regard and affection to the parent body whose members 

 have laid the foundation on which we are trying to build ! May the record 

 of the Royal Society be as glorious in the future as it has been in the past, 

 and may she continue to possess the confidence and admiration of all who seek 

 the advancement of Natural Knowledge ! On behalf of the PHYSICAL SOCIETY
