separate, being kept together by the carpet of silk which the larva 
spins on the inside. The peculiar jumping motions of the carpel are 
thus produced, as first described by Prof. Riley in the Transactions of 
the St. Louis Academy aforementioned. The full-grown larva, by its 
holding fast to the silken lining by its anal and two hind pair of 
abdominal pro-legs, which have very strong hooks, then draws back 
the head and fore body, the thoracic parts swelling and the thoracic 
legs being withdrawn, The contracted parts being then suddenly 
released, the larva vigorously taps the wall of its cell with its head, 
sometimes thrown from side to side, but more often brought directly 
down as in the motion of a wood-pecker when tapping for insects. 
The seed will thus move whenever warmed for several months during 
the winter, because, as with most tortricid larve, this one remains a 
long time in the larval state after coming to its growth and before 
pupating. 
Remarkable as are the movements of this seed, Prof. Riley remarked 
that they are thrown into the shade by a little jumping gall produced 
on the leaves of our post-oak and other oaks. This is a little, spherical, 
seed-like gall, and the insect within, which produces the fly known as 
Cynips saltatorius, can make it bound twenty times its own length. 
Here the motion is imparted by the insect in the pupa, and not in the 
larval state.—Scientific American, June 13th, 1891. 
ARCHEOLOGY AND ETHNOLOGY.!

historic Archeology of Paris, 1889.—( Continued from page 592). 
Fifth Question: ‘The Relation Between the Civilization of Hall- 
stadt and Other Danubian Stations, and those of Mycenz, Tirynthe, 
Hissarlik, and the Caucasus.”’ 
This question brought up the most excited, because the only personal, 
discussion of the congress. Captain E. Boetticher presented a paper 
criticising the excavations made at Hissarlik by M. Schliemann. 
Captain Boetticher was of opinion that the hillside of Hissarlik which 
had been explored by M. Schliemann did not contain, as M. Schlie- 
mann, thought, the débris of the walls or the temples or palaces, but 
that it had been a necropole or crematory, a place for incineration or 
cremation, and that the superposed territory contained the cinerary
