y impressed that peculiarities and distortions are entailed on
the offspring; hence, there is wisdom shown in banishing particolored or
objectionably tinted animals, and those that show deformities or faulty
conformation. Hence, too, the importance of preventing prolonged, acute
suffering by the pregnant mare, as certain troubles of the eyes, feet,
and joints in the foals have been clearly traced to the concentration
of the mother's mind on corresponding injured organs in herself. Sire
and dam alike tend to reproduce their individual defects which
predispose to disease, but the dam is far more liable to perpetuate the
evil in her progeny which was carried while she was individually
enduring severe suffering caused by such defects. Hence, an active bone
spavin or ringbone, causing lameness, is more objectionable than that in
which the inflammation and lameness have both passed, and an active
ophthalmia is more to be feared than even an old cataract. For this
reason all active diseases in the breeding mare should be soothed and
abated as early as possible.

EXTRA-UTERINE GESTATION.

It is rare in the domestic animals to find the fetus developed elsewhere
than in the womb. The exceptional forms are those in which the sperm of
the male, making its way through the womb and Fallopian tubes,
impregnates the ovum prior to its escape, and in which the now vitalized
and growing ovum, by reason of its gradually increasing size, becomes
imprisoned and fails to escape into the womb. The arrest of the ovum may
be in the substance of the ovary itself (ovarian pregnancy), in the
Fallopian tube (tubal pregnancy), or when by its continuous enlargement
it has ruptured its envelopes so that it escapes into the cavity of the
abdomen, it may become attached to any part of the serous membrane and
draw its nourishment directly from that (abdominal pregnancy). In all
such cases there is an increase and enlargement of the capillary blood
vessels at the point to which the embryo has attached itself so as to
furnish the needful nutriment for the growing offspring.

All appreciable symptoms are absent, unless from the death of the fetus,
or its interference with normal functions, general disorder and
indications of parturition supervene. If these occur later than the
natural time for parturition, they are the more significant. There may
be general malaise, loss of appetite, elevated temperature, accelerated
pulse, with or without distinct labor
