OF 



SEASCAPE PHOTOGRAPHS. 



(PERMANENT CARBON.) 



The Art Journal : Extract from the Paper on " Picture 

 Photography." — " It would be difficult to praise too highly the 

 success with which the effect of moving, heaving water has been 

 rendered in the superb composition ' Roll on, thou deep and dark 

 blue Ocean, roll!' . . . Mr. Worsley-Benison's sea composi- 

 tions are triumphs of artistic arrangement." 



The Royal Societies' Ladies' Conversazione : From The 

 Times Report. — " Mr. Worsley-Benison's series of seascape 

 photographs . . . were magnificent examples of photographic art." 



Extract from Mr. Gleeson White's Paper, •' The Sea, as Mr. 

 Worsley-Benison Photographs it," in The Photogram, January, 

 1898. — "One doubts if any pictures of English scenery would re- 

 awaken the peculiar memories of fields and dales so vividly as 

 these photograms awaken memories of the sea. Indeed, it is very 

 hard to remember that it is Mr. Worsley-Benison's skilful records 

 which should be the text of this discourse ; you forget his share as 

 you study them, and think not of a pictured ocean, but of the real 

 entity itself. For, oddly enough, it is always the sea one finds, 

 never a sea. . . . To confess that one is entirely captivated by the 

 literal truth of Mr. Worsley-Benison's really beautiful work is 

 perhaps in a way the finest compliment you could pay him. To 

 own how admirably be has chosen the spot to pitch his camera, 

 and the moment to expose his plate : to discuss the admirable 

 development of his pictures, those harmonious skies and accessories, 

 their artistic ' placing ' within a given space, seems almost imper- 

 tinent after owning he has made criticism appear secondary by the 

 sheer beauty of truth." 



Knowledge.— Extract from the Paper on "The Artistic Study 

 of Waves," by Mr. Vaughan Cornish, M.Sc. — "Mr. Worsley- 

 Benison's ' Westby ' series of Photographs are the finest studies 

 with which I am acquainted. There is no sea-painter, however 

 skilful, who would not find much to repay him in the careful study 

 of such photographs. Above all, the foam is rendered as no painter 

 ever rendered it ; not merely the thin film of foam of which I have 

 already spoken, but the thick white froth of the breaker line, which 

 looks by daylight like whipped cream, but by moonlight is changed 

 to molten silver." 



The Series sent for inspection.

BACTERIA. 



The study of these simple plants enforces the lesson that tidiness, 

 cleanliness, and purity lead up to the health and welfare of 

 individuals and communities, as also to the prosperity of industries ; 

 that moisture and decaying organic matter favour the multiplica- 

 tion of bacteria, while the dispersal of this matter as dust favours 

 their distribution ; that strong light, pure air, hot water, steam or 

 dry heat are deadly to all the disease-producing forms ; and that 

 an intelligent cultivation of our bacterial floras would be a benefit 

 to all.
