breed, these authorities fouiul that the period of gestation in Merinos 

 averaged 150-3 days; while with Southdowns it was only WA-l days, 

 or six days loss. 



In the Merinos, for the male Lamb the average period was \')\\ 

 days, female Lamb loO-li days, and twins 149-9 days ; and in the South- 

 downs, for the male Lamb 14-4 -7 days, female Lamb 144- 1, and twins 

 144 days. 



Mayne asserts that the Goat goes a little longer than the Sheep — tlie 

 average being live months and some days ; another authority gives it 

 as 148 days. 



Pig. 



The Pig is usually pregnant four months, or according to some au- 

 thorities three months, three weeks, and three days. Baumeister and Kuetf 

 give the longest period as 130 days, the shortest 110 — average, 120 ; 

 while Dieterichs gives 109 days as the shortest and 133 as the longest 

 — average, 115 to IK) days ; and Magne says that it is rarely less than 

 109 or more than 120 days. Rainard noted the period of gestation in 

 6o Pigs, and reports it to be as follows : 



2 instances 104 days. 



The average was, therefore, 119 days, the interval between the longest 

 and shortest periods being 23 days. 



Bitch, 



The Bitch goes with young about two months, or from 5H to 05 days ; 

 the average being 63 days or nine weeks. Baumeister and Rucff state 

 the shortest period to be 55 days, and the longest 70 — the average being 

 60 days. 



Cat. 



The Cat is pregnant from 50 to (JO, 62, or even 04 days, the average 

 being 55 days or eight weeks. 



SECTION v.— GEMKLLI PAROUS AND MI'LTIPAROUS PREGNANCY. 



Among the domestic animals there are species wliich are naturally 

 uniparous — produce only one at a birth ; and others which, in a normal 

 or physiological manner, bring forth two, three, or more at a time, and 

 are therefore designated (jemelli pi irons or mnltiparous, gestation being 

 known as double, triple, quadruple, etc. As examples of uniparous 

 animals, we may give the Mare, Ass, ('ow, Sheep and Goat ; while we 

 may cite the Pig, Bitch, and Cat as mnltiparous creatures. As multi- 

 parity is normal with the latter, we shall not specially refer to them, 

 but will allude to those creatures which, naturally uniparous, sometimes 

 bring forth more than one progeny at a time. 



It is seldom that twins or triplets are produced by the larger 

 domesticated animals, and particularly by the Mare and Ass, though 

 instances are recorded of these ; while in the Cow, Sheep, and Goat
