    ejaculated would be unfertile, but that anorcliids would be im- potent and incapable of any ejaculation. MM. Monod and Terrillon (loc. supra cit., p. 19) hold that this is going too far, as some cryptorchids are quite as impotent, quite as feminine in asj)ect, as the anorchifls mentioned above. A correct diagnosis must, therefore, be sometimes impossible during life. This sub- ject is again alluded to at p. 45. Section II. AB]SORMALITIES TN THE TRANSIT OF THE TESTICLE. A. Incomplete Transit of the Testis. Retention of the Testis. B. Malplaced Transit, or Ectopia of the Testis.-—-Tliese abnormalities, being more common, are of much greater practical importance than the preceding. Definition.—It will be suitable here to define clearly the very varying terms which have been used synonymously, and somewhat loosely, for very different conditions. Anorchism, with the prefix single or bilateral, should be kept for those cases in which one or both testicles, or their annexa, are absent (p. 23). Monorchism is the simple equivalent of single anorchism. Cryptorchism, single or double, should be retained for those cases in which one or both testicles, though present, are hidden out of sight. This term is therefore the equivalent of abdominal or iliac retention of the testis {vide infra). Ectopia of the testicle should, for accuracy and convenience of description, include the following varieties : (a) Incompleted normal descent of the testicle, or retention of the testicle, and (j3) abnormal descent of the testicle, or ectopia testis. These abnormalities are of much greater practical importance than the preceding. Frequency.—I believe this to be greater tlian is usually allowed. The well-known statistics of Wrisberg (Comvient. h'oc. Beg. Scicnt. Goett, 1778)—in which in 103 male infants examined at birth, 73 had both testicles in the scrotum; in 21, one or both were in the groin ; in 9, one or both were in the abdomen—are fallacious, as at this early age the testicle has frequenrly not completed its descent, and the retention is thus in many cases only temporary. The above proportion is there- fore too high. On the other hand, the statistics taken from a large number of recruits, and therefore from healthy and other-
