OBITUARY. 
the College for three years, during which period he communicated to the ‘Philosophical 
Magazine ’ his first published research, entitled “Examination of a Native Sulphuret of 
Bismuth.” . 
In 1831, Messrs. Truman, Hanbury, and Buxton, desiring the services of an able 
young chemist in their great brewing establishment, engaged Mr. Warington, on the 
recommendation of Dr. Turner, and with them he remained till 1839. His connection 
with the brewery did not prevent his independent pursuit of chemistry, and during this 
period he contributed papers to the ‘ Philosophical Magazine,’ “ On the Establishment 
of a System of Chemical Symbols” (Sept. 1832), and “ On the Action of Chromic Acid 
upon Silver” (Dec. 1837). 
On the death of Mr. Hennell in 1842, Mr. Warington was appointed Chemical 
Operator to the Society of Apothecaries, a position he continued to hold till about a 
year before his death. His professional engagements now became numerous, and he 
was much employed as a scientific witness or adviser in important cases coming before 
the courts of law. 
Mr. Warington’s scientific activity manifested itself in various ways. In 1841 he 
took an important part in the establishment of the Chemical Society, and became one 
of the original secretaries, which post he held for ten years. He was one of the pro¬ 
moters of the Royal College of Chemistry; and he took part in the*formation of the 
Cavendish Society, and held the office of secretary for three years. He was chemical 
referee of four of the principal gas companies of the metropolis. He served as juror in 
the chemical section of the International Exhibition of 1882, and was appointed to a 
similar office in the Paris Exhibition of 1867, but was unable 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 trans¬ 
lation 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 under¬ 
took a still important share, along with Dr. Redwood, in the preparation of the British 
Pharmacopoeia of 1867, although his failing health allowed him but partially to per¬ 
form his task. 
Amid these varied labours of his active and useful life, Mr. Warington continued to 
furnish numerous contributions on chemical and pharmaceutical 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 compensating 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 ‘ Annals of Natural History,’ and also furnished the sub¬ 
ject 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 Influ¬ 
ence 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 Bud- 
leigh Salterton, in the county of Devon, on the 12th of November, 1867. 
Mr. Warington was remarkable for his varied taste and constant activity as an 
observer; he may be said, indeed, to have passed from one subject to another with too 
great a facility, and consequently his completed investigations bear but a very small 
proportion to the number of subjects he had continually under examination. He was 
of an exceedingly cheerful and genial disposition, and a man of simple, unaffected piety.
