ANTENATAL PATHOLOGY 



1957 



There can be no doubt that this is the right step to combat such 

 diseases as puerperal fever and infantile mortality, but in order 

 to insure the birth of a healthy child the mother should be medically 

 advised in the early days of pregnancy, and suitable medicines 

 given, if necessary, as so many monstrosities and abnormalities 

 appear in the tropics that some care is required to diminish their 

 numbers.

Since the days of Licetus many attempts have been made to 

 classify monstrosities by such authorities as Buffon, Blumenbach, 

 Meckel, Bischoff, Foerster, Fischer, Ahlfield, and others, while 

 Ballantyne has written a most interesting book on the subject. 



We have always used the classification introduced by Hirst and 

 Piersol in 1892, and have found it useful. It is as follows: — 



Hemiterata. — Anomalies of volume, form, colour, structure, disposition, 

 number, and existence. 



Heterotaxis. — Splanchnic inversion and general inversion. 



Hermaphrodites. — True, including bilateral, unilateral, and lateral, and false 

 — i.e., with double sexual external genitalia, but unisexual glands.
