every additional year in which it should be suffered to propagate

For further observations by Mr. Spence on the Scolytus destructor, 
see Journal of Proceedings, June 6th, August 1st, and October, 
1836; and April 3d, 1837. 
The Rev. E. Stanley, (Bishop of Norwich,) who was present as 
a visiter, observed in reference to Mr. Spence’s notices, that the 
discovery of M. Bassi appeared to afford a solution to the diffi- 
culties connected with the vegetating wasp of the West Indies, 
which he considered as analogous to the larvae of the silkworm 
attacked by fungi, adding, that he had himself possessed a living 
caterpillar of the tussock-moth, near the head of which a fungus, 
one-fourth of an inch long, had protruded, and which subsequently 
caused the death of the caterpillar. The same gentleman also 
observed, with respect to the Scolytus destructor, that that insect 
appeared to him to have been improperly regarded as the primary 
cause of the injuries suffered by the elm-trees, believing that trees 
already diseased were alone subject to its attacks : mentioning a 
circumstance which had occurred near Chester, where some young 
and luxuriant trees had been attacked, but of which it was ascer- 
tained that the roots had penetrated into the blue clay, which had 
caused the gradual decay of the trees, and which consequently 
became more and more congenial to the Scolytus.
