REGENERATION OF BONE. 
at a moderate price. Mr. Sinclair mixes with the lye a por¬ 
tion of aloes which abound in many parts of our colony. 
With a large soup-pot kept boiling with lye, and a couple of 
large tubs, Mr. Sinclair, with a few servants, will wash five 
or six hundred sheep per day, and he assures me he has 
found this remedy very successful. At all events it is a 
very cheap one, attended with no danger, and well worth 
trying. 
“ I thought of using this lye many years ago. The idea 
came into my mind through having had given to me a 
mangy young dog, which I put into a soup-pot full of lye, 
and allowed it to swim about for some minutes. In a week 
or two that dog was perfectly clean, and the young hair grew 
fast. I mentioned this circumstance to Mr. Collett, senior, 
of the Cradock district, and we were both of opinion that 
tye, made from the ghauna bush, would be a good remedy 
for the scab or brandziekte in sheep. Had I remained much 
longer on either of my farms I certainly should have 
tried it.

REGENERATION OE RONE. 
The Academy of Sciences has received an interesting com¬ 
munication from Dr. Demeaux, on the regeneration of cer¬ 
tain bones of the face by the mucous periostic membrane. 
Our readers know 7 that the larger bones have been success¬ 
fully renewed bv preserving the periosteum, as has been 
done by Drs. Sedillot, Maissonneuve, and others, but in¬ 
stances were wanting of a similar regeneration of the facial 
bones. Dr. Demeaux relates the following case :—A young 
man, aet. 22, w r as in 1855 afflicted with a naso-pharyngeal 
polypus of extraordinary size, which had seriously injured 
the face, and destroyed a portion of the palate bone on one 
side, so that the tumour protruded into the cavity of the 
mouth, being only separated from it by the mucous mem¬ 
brane, which had even been considerably thinned. The 
tumour was extirpated, and it was then ascertained that a 
surface of fifteen square millimetres at least w r as wanting in 
the bone. Six years later Dr. Demeaux met his patient 
again, and found that the bone had been completely regene¬ 
rated. The second case stated by Dr. Demeaux is still
