I took up the matter again and found not only my old observa- 
tions corroborated, but also, and especially this autumn (1909) observed 
a new, and it seems to me very interesting, circumstance viz that the 
Boring Beetle very often also knocks in an energetic way 
before (as a rule some few hours) the coming barometrical mini- 
mum has been able to induce movements on the barometer. 
This has been exceedingly interesting to me. 
Whether the Anobium can be considered as a good and true weather 
prophet or not may of course, if I can say so, in the first line become 
a question of curiosity. That more or less strong alterations in the air 
depressions directly or indirectly are able to cause the insect to act in 
some way, in casu to knock, might, I think, be explained in a some- 
what natural way, but that the insect acts still before the glass begins 
to fall, that means before the air depression has reached the place, is 
very surprising, and it gives a hint of forces (electrical?), of which we 
till now, as far as animal activity goes, are not fully acquainted of. 
I feel sure that every Entomologist, who has the opportunity of 
studying the Boring Beetle, may be pleased in observing its knocking 
in relation to the change of weather or the barometrical minima, 
and I also feel convinced that he will not only be able to corroborate 
my observations but also to add new facts to them. But I may as 
well notice that this study must be the sake of the entomologists of 
the „country“. Those who live in the towns will not have the best 
opportunity. The noise in large cities will quite suppress the little 
fellow’s, let us say, calling its better half part!
