appointed to a similar office in the Paris Exhibition of 1867, but was un- 

 able to discharge the duty. 



Mr. Warington's scientific acquaintance with Pharmacy, and the large 

 experience he had acquired in the practice of the art, led to his being 

 employed in revising the translation of the London Pharmacopoeia, left 

 unfinished by Mr. Phillips, and in aiding in the construction of the 

 Pharmacopoeia of 1851. For a like reason he was consulted by the 

 Committee appointed to prepare the British Pharmacopoeia of 1864, 

 and undertook a still more important share, along with Mr. Redwood, in 

 the preparation of the British Pharmacopoeia of 1867, although his failing 

 health allowed him but partially to perform his task. 



Amid these varied labours of his active and useful life, Mr. Waring- 

 ton continued to furnish numerous contributions on chemical and pharma- 

 ceutical subjects, to the Memoirs and Quarterly Journal of the Chemical 

 Society, the Philosophical Magazine, and other periodical works. To 

 the Transactions of the Microscopical Society, of which he was an 

 efficient member, he contributed several papers, and he was the inventor 

 of a portable microscope, which has been favourably spoken of. 



A subject of more general interest, which furnished an agreeable and 

 instructive study to Mr. Warington for many years, was the mode of life 

 of aquatic animals and plants preserved in the aquarium ; and especially 

 the maintenance in a limited quantity of unrenewed water of the chemical 

 conditions necessary to their existence, through the mutually compensa- 

 ting operations of animal and vegetable organisms upon the medium 

 they inhabit. The results of his observations were published, from 

 time to time, for the most part in the * xlnnals of Natural History,' 

 and also furnished the subject of a Lecture delivered by Mr. Warington 

 at one of the Friday Evening Meetings of the Royal Institution. The 

 latest yield of these long-continued researches which he lived to make 

 known, forms the subject of a valuable and interesting paper " On some 

 Alterations in the Composition of Carbonate-of- Lime Waters, depending on 

 the Influence of Vegetation, Animal Life, and Season," communicated to 

 the Royal Society within a month of his death, and published in the 

 'Proceedings' of December 1867. 



In 1835 Mr. Warington married Miss Elizabeth Jackson, by whom 

 he has left a family. He was elected a Fellow of the Royal Society in 

 June 1864 ; he died at Budleigh Salterton, in the county of Devon, on 

 the 12th of November 1867. 



Mr. Warington was remarkable for his varied taste and constant acti- 

 vity as an observer ; he may be said, indeed, to have passed from one 

 subject to another with too great a facility, and consequently his com- 

 pleted investigations bear but a very small proportion to the number 

 of subjects he had continually under examination. He was of an exceed- 

 ingly cheerful and genial disposition, and a man of simple unaffected 

 piety.
