Functions of the Generative Organs. 143 
I may give one instance as particularly illustrative of 
this fact. A pure-bred white English terrier, belonging 
to my brother, by mischance, had connection with a 
yellow-and-white mongrel, to which she conceived, and in 
each of her succeeding three litters, though put to stainless 
dogs purely white, the whelps were marked precisely like 
the first litter, yellow and white! 
3. When the bitch has been served, she should again be 
secluded, for she will then be more likely to retain the im- 
pression of the dog she has been mated with, and not only 
so, but danger of a second conception will be avoided. 
This may appear contrary to the laws of nature, but it is 
nevertheless a fact that bitches will re-conceive.* Of this 
I have had ocular demonstration. One instance I will 
give. A full-sized black-and-tan terrier, belonging to a 
relative of mine at Abbots Bromley, had connection with a 
dog of the same species ; within an hour afterwards I saw 
her connected with a curly half-bred black-and-white sheep- 
dog. When the period of parturition arrived, she gave 
birth to two whelps: one, to all appearance, a pure-bred 
black-and-tan, the other a rough-coated black-and-white 
whelp, double the size. 
* Inthe bitch, many observers have assured themselves that super- 
foetation is by no means unfrequent. Rainard, Blaine, and others 
speak of it. Blaine says: “Iam disposed to think that bitches are 
capable of superfcetation; that is, they conceive more than once. If 
this is the case, a bitch may copulate to-day, and become impregnated, 
and in a day or two she may copulate again, and again become impreg- 
nated. This is not frequent, I believe; but it certainly does happen, 
or we could not account for the different periods at which the progeny 
sometimes appear. I have known a week, and in one case even ten 
days, intervene between the puppings ; but one or two days is not at 
all uncommon. As a still more convincing proof, the whelps often 
appear of different kinds.” (The italics are mine.—J. W. H.) 
“Tt must be remembered ‘that the bitch remains in ‘heat’ for three 
or four days, and will seek repeated intercourse with the male during 
that period. It must, therefore, either be concluded that the last inter-- 
course was the successful one, or that one or more ova were impreg- 
nated at each copulation.”—Fleming’s “ Veterinary Obstetrics,” 
Anomalies in Gestation, p. 153.
