104 HISTORY OF GESTATION. 



are two, three, or four foetuses. 3. Complicated pregnancy, where 

 a polypus, a great quantity of water, or any diseased state of the 

 product of the conception, or of the womb itself takes place. 



The second comprises four varieties determined by the seat occu- 

 pied by the fecundated germ; so that authors admit, 1. An ovarian 

 pregnancy; 2. An abdominal or peritoneal pregnancy; 3. A tubal 

 pregnancy; and 4. A mixed or interstitial pregnancy. 



After having observed that a great variety of diseases, sometimes 

 give rise to most of the symptoms of pregnancy, the French writers, 

 adopting a still more general first division, have established a true 

 and 2i false or apparent pregnancy, differing from each other in this, 

 that the former is characterised by the presence, and the latter by the 

 absence of the fcstus; they have next described false pregnancy as 

 ventose, serous, sanguine, polypous, cancerous, nervous, molar, hy- 

 daiic, &c., accordingly as the increased size of the belly depends on 

 the presence of gas, water, blood, polypous or other tumors in the 

 Avomb, the existence of a scirrhus, an hydatiform or fleshy mole, an 

 undefinable nervous state, &c.

 Of Uterine Pregnancy. 



263. As soon as pregnancy takes place, important and numerous 

 phenomena are manifested in the economy. Of these some are 

 local, physical, material: others are variable, transient, general: some 

 are common to all kinds of gestation, while others are peculiar to 

 some sorts only. 



As uterine pregnancy comprises almost all of them, and further, as 

 it constitutes the only normal kind of gestation in the human species, 

 I shall speak, in the first place, only of those which belong to it, and 

 shall not treat of the special phenomena until I come to the article in 

 which I shall designate the means of distinguishing it from all the 

 rest. 



264. The constitutional movement occasioned by copulation is 

 only momentary, both in women and in men, where fecundation is
