remains imperforate as before, and is beyond the reach of surgical 

 remedy. It may be added, that the subject of this history recognizes 

 an increase of sexual feeling at and soon after the periods of enlarge- 

 ment of the ovary. 



The second case was that of a young woman who had attained the 

 age of twenty without having menstruated. She was a tall, strumous- 

 looking person, in weak health. There had not been any well- 

 marked efforts at menstruation, but she had suffered slightly from 

 lumbar pain. The mammae were well developed. The pelvis was 

 fairly formed. On examination I found the two ovaria just appear- 

 ing beyond the external abdominal rings, and readily returning by 

 pressure into their respective inguinal canals. They were of equal 

 size and similar shape, being ovoid bodies about the size of small 

 chestnuts. They were not tender when touched, although organi- 

 cally sensitive, and she had never experienced pain in them. The 

 external sexual organs were somewhat less perfectly developed than 

 usual ; the vaginal orifice was closed, and no trace of a canal or 

 uterus could be detected by exploration with a catheter in the blad- 

 der and the finger in the rectum. These organs, as in the former 

 case, were absent. During the time I saw the patient, which was 

 only for two months, the ovaria did not enlarge, although her general 

 health improved. 



II. " Further Observations on the Anatomy and Physiology of 

 Nautilus" By JOHN D.- MACDONALD, Esq., Assistant 

 Surgeon R.N. Communicated by Captain DENHAM, R.N., 

 F.R.S. Received January 13, 1857. 



Both Professors Owen and Valenciennes noticed that the hollow 

 subocular process of their specimens of Nautilus Pompilius was not 

 tentaculiferous, and I may be permitted to say that this was also true 

 of several examples of Nautilus Pompilius, and one of N. macrom- 

 phalus, examined by me. But there is still another matter worthy 

 of remark with reference to this process, namely, that its cavity may 

 be traced downwards, inwards, and a little forwards, to within about 

 the twentieth of an inch of the auditory capsule ; indeed it would
