Olservations on Cydofui in the Human Subject, etc. 269 



the skull of a cyclopean lamb, which he allowed us to 

 examine, was only one of a large number of similar monsters 

 begotten by the same ram. 



In the human subject cyclopea appears to be commoner 

 amongst females than in- males, 55 of those mentioned by 

 Hannover being females and 16 males; in the other cases 

 the sex was not recorded. As a rule these monsters are 

 born between the sixth and eighth month of gestation. They 

 seldom breathe after birth, although in a few cases life 

 appears to have been prolonged for a few hours. 



We have based our observations on the following speci- 

 mens to which we have had access ; the more important of 

 these we will briefly describe. 



(a.) Human Cyclojn. — This occurred in the practice of Dr 

 William Craig, of Edinburgh, to whom we are indebted for 

 the opportunity of making a complete dissection. 



The specimen was a well-nourished male foetus. It was 

 19 inches in length, had an ossific centre in the lower ex- 

 tremity of each femur, and, in fact, presented the usual in- 

 dications of having been born at the full time. In addition 

 to the cyclopean malformation this foetus presented several 

 minor abnormalities. There were six toes on each foot, but 

 the supernumerary one on the right side was very small. 

 The external genitals exhibited a slight tendency to resemble 

 in appearance those of the female, for the fold of integument 

 forming the scrotum passed upwards and inwards, so as to 

 meet in front of the pubes in a somewhat similar manner to 

 that in which the labia majora unite to form the mons veneris. 

 The penis was small, and almost concealed by the above- 

 mentioned fold. The left testicle had descended into the 

 scrotum, but the right one was still in the abdomen. 



The upper part of the head was smaller than normal, and 

 presented a constriction just above the level of the pinnae of 

 the ears. In the middle line below the forehead was situated 

 a freely movable snout or proboscis. This was about an 

 inch in length, and was traversed in its whole extent by a 

 single canal, which terminated in front by an opening at its 

 free extremity. Below the snout there was a small lozenge-
