Abstract
#1. The excretion rate in the toxaemias of pregnancy was in the
vast majority of cases below that in a normal pregnancy.
#2. The excretion rate during the later stages of a normal
pregnancy was slower than in the non-gravid woman.
#3. The average amount excreted in the toxaemias of pregnancy
in three hours was 713 c.c.s.
#4. The average amount excreted in a normal pregnancy (late
stages) in 2.5 hours was 1030 c.c.s.
#5. The average amount excreted in the non-gravid female in
2 hours-was 1077 c.c.s.
#6. The maximum amount excreted in 3 hours in the cases of
a toxaemia of pregnancy was 1280 c.c.s. and the minimum
198 c.c.s.
#7. The curve of excretion in the toxaemias of pregnancy was
much flatter than in the non-gravid woman.
#8. In the cases of normal pregnancy and in the non-gravid
female the maximum excretion was.between 60 and 75 minutes.
In the cases of toxaemia of pregnancy it was between 45 and
60 minutes.
#9. No rise of blood pressure accompanied the sudden intake of
1000 c.c.s of water. In most cases there was a fall often
as much as 10 to 20 m.rn. Hg..
#10. Oedema of the legs alone was not associated with a fall in
the excretion rate.
#11. The higher the initial blood pressure the lower was the
excretion rate.
#12. No sign or symptom of increased intracranial pressure
