184 THE HISTORY OF ANIMALS. [B. Til. 



ant. Its parts are visible, both those of generation, and all 

 the rest ; and the eyes are very large, as in other animals. 

 It' the female foetus perishes within the three months, it 

 generally appears without divisions. If it survives to the 

 fourth month, the parts appear formed. 



5. The whole completion of the parts is more slow in the 

 female than in the male, and parturition is more frequently 

 delayed to the tenth month. After birth, females attain to 

 youth, and puberty, and old age, more rapidly than males, 

 and those that have borne many children more rapidly than 

 others, as it was observed before. 



CHAPTER IV. 



1. WHEN conception has taken place, the uterus usually 

 closes immediately for seven mouths. In the eighth month it 

 opens, and the foetus, if properly developed, begins to descend 

 in the eighth month. If the foetus is not properly deve- 

 loped, but checked in the eighth month in parturition, 

 women who bear in the eighth month do not exclude it, nor 

 does the foetus advance downwards in the eighth month, 

 and the uterus does not open itself. It is a sign that it is 

 not properly developed, when it is born before the circum- 

 stances I have described take place. 



2. After conception, women suffer throughout their whole 

 body, and their sight becomes dim, and they are afflicted 

 with headache. In some, these symptoms occur very soon, 

 as early as the tenth day ; in others they are delayed, in 

 proportion as they have an abundance or deficiency of super- 

 fluous matter in their bodies. Nausea and vomiting often 

 seize upon them, and on those especially in whom the puri- 

 fications become stagnant, and do not yet fly to the mamma3. 

 Some women suffer at the commencement of pregnancy, and 

 others in the more advanced stages, when the foetus be- 

 gins to grow. Eetention of urine also frequently attacks 

 them at last. 



3. Those that are pregnant with a male foetus, usually 

 pass through the time more easily, and retain a better 

 colour throughout. If a female is conceived, the contrary is 

 the case ; for they are generally more discoloured, and 

 suffer more during the period of gestation. In many cases 

 the legs swell, and a swollen condition of the flesh is also com-
