NOTES. 193 



grafting of a second fruit on the parent stem materially alters the 



type and quality, not only of the original fruit, but also of the 



graft, and it is sometimes gravely asserted that " blood oranges " 



are obtained by grafting the pomegranate on to the orange. This, 



says the consul^ is a complete fallacy. Both fruits retain their 



original quality, and neither borrows anything from the other. 



There is thus no difference between the lemons grown in the 



orange grove from those grown in the grove where lemons alone 



are cultivated. — Pharmaceutical Journal.

 Prehistoric Human Teeth. — At a meeting of the Students' 



Society of the National Dental Hospital, held October 9th, 1896, 

 Mr. Loftus H. Canton showed some interesting teeth which were 

 found in a cave at Seturitz, Basses Pyrenees. These teeth, sup- 

 posed to be those of the Cave Bear, were found in a bed of 

 guano, which was in some places thirty feet deep. Along with 

 them were large quantities of animal remains, and one curious 

 feature was that five specimens of human teeth were found in the 

 same place, together with human remains. Whether the human 

 remains were contemporary with those of the animals, Mr. Canton 

 could not say. The deep bed of guano was covered by a layer of 

 stalagmite, varying between one to five inches in thickness, and 

 above this another layer of guano was found, but not so deep as 

 the lower layer. Finally, at the top of all was another layer of 

 stalagmite. The fact of the remains being at such a great depth 

 seemed to imply that they were of great antiquity. — -Journ. British

Preservation of Flowers. — The following is a very old 

 method of keeping flowers without loss of colour : — Dry some 

 very fine, pure siliceous sand in the sun or oven ; then take a 

 wooden, tin-plate, or pasteboard box sufficiently large and deep, 

 and place your flowers inside erect ; then fill the box with sand 

 until the last is about an inch above the top of the flowers. The 

 sand must be run in gently so as not to break the flowers. Cover 

 the box with paper or perforated cardboard and place it in the sun- 

 light, oven, or stove; continuous heat gives the best results. After 

 two or three days the flowers will be very dry, but they will have 

 lost none of their natural brilliancy. — Journal oj Horticulture,
