CAMPHORA. 121 
himself used it, with benefit in delirium tremens. Quarin 
(I. c., p. 57) warns against too large doses of Camphor, as 
it, among other things, produces also “ oculos torvos inflam- 
matos.” Murray (J. c., pp. 495, 523) praises the latter in 
inflammations of the eyes and eyelids; wherein many agree 
with him, and among others, Most (Encyclop. Pocket Vocab. of 
Pract. Pharm., Rostock and Schwerin, 1841, p. 209), who 
advises the use of Camphor for “recent and old ophthalmia 
catarrhalis and rheumatica.” According to Moreau, Camphor 
acts in ophthalmia militaris, alternately stimulating and calm- 
ing, by exciting in the part it comes into contact with, 
warmth, redness, and such burning pain that the eye in- 
stantly swims in tears, and whereas the burning and tears 
are only transitory, the redness and irritation disperse, and 
the bulbus returns to its normal condition (Annales d’ Ocu- 
liste et Gynécologie, vol. i. livr. 20, in Schmidi’s Annuary, vol. 
xxviii. No. 1). “In otalgias,” says Kraus (1. c., p. 479), 
“one can only expect aggravation from the customary putting of 
Camphor into the ears, which also generally proves to be the 
case.” That Camphor induces salivation has been evidenced 
by the experiments of Vincenzo Menghini (Comment. de 
Bononiens, Scient. et Art. Instit., p. 199); but that it removes 
salivation, particularly the mercurial, is also well known. 
Friedlander calls the specific virtue of Camphor against mer- 
curial salivation, and strangury after cantharides, fictitious ; and 
adds: “ By the idea of specific there can be nothing else under- 
stood than the action of a substance on a formation of the body ; 
now this action is at all times, by the organic laws of animal 
life, stimulation ; consequently Camphor ought rather to aug- 
ment than restrain the agencies of both the above substances ; 
meanwhile, if such is the case, the phenomenon must then 
proceed from another healing principle of Camphor.” The 
fact contested by Friedlander is established, and (as is partly 
evidenced by the above) the principle of homeeopathy explains 
the incident. Camphor produces inflammatory irritation in
