that eighteen patients treated for purulent or simple ophthal- 
mia, general or partial, have all been cured in about thirteen 
days. 
M. Hipp. Larrey, who had long before M. Bonnafont 
employed the same means, thinks that the cases where it may 
be useful are the following: — In mechanical injuries to the 
globe of the eye, such as wounds, contusion, and commotion ; 
ophthalmoptosia, exophthalmia, congestion, hydrophthalmia, 
and the different kinds of ophthalmia. The occlusion of the 
eyelids is particularly important in cases of ulceration of the 
cornea, of kerat-odei-tis,of staphyloma, and diseases of the iris. 
Professor Velpeau does not agree with his colleagues as to 
the efficacy of the occlusion of the eye. He states, that by 
other modes of treatment a cure is as quickly obtained, if not 
much quicker, than by occlusion. He admits, nevertheless, 
that sometimes occlusion may prove useful, as, for instance, 
in cases of conjunctivitis and kerat-odei-tis, and after wounds 
of the globe of the eye . — Medical Times and Gazette . 
ON THE EXTIRPATION OE THE SUPRA RENAL CAPSULES. 
By Dr. Brown-Sequard. 
In a recent communication to the Societe de Biologie , Dr. 
Brown-Sequard it appears has almost completed the exposition 
of the results of his researches upon the physiology and patho- 
logy of the supra-renai capsules. He has found that the ex- 
tirpation of the two capsules in dogs, cats, rabbits, and guinea- 
pig is a cause of very rapid death. In rabbits the average 
duration of life after this operation is 9 hours ; out of 25 
animals of this species, only 1 survived 13 hours, and almost 
all lived 8, 9^ or 10 hours only. In adult dogs and cats the 
average length of life has been 14 hours, and the greatest 
period has been 17 hours. In newly born kittens life lasted, 
in one case 38 hours, in a second 49. After the extirpation 
of only one of the supra-renai capsules, life lasted 15 or 16 
hours, on an average, in rabbits and guinea-pigs, and 27 
hours, on an average, in dogs and cats. — Medical Times and
