Gene, by the simple act of placing a fresh battery in the car you caused deep 
rumblings from within the earth. Placing a connection on the negative of said 
battery, you awoke LUCAS, Prince of Darkness who displayed his power to you 
in a flash of light. Had you finished the job by making connection with the 
positive terminal, the course of history could have been changed :)
Now, in all honesty, I do not see how placing only a negative connection on 
the car you could have had ANY sparks if there was indeed nothing touching 
the positive terminal. If I was doing this, I would try again, checking that 
there is nothing touching the positive terminal. I would then hold a 2 amp 
fuse to the postive terminal, and with everything in the car turned OFF, I 
would touch the end of the positive cable to the 2 amp fuse that I would be 
holding in contact with the positive terminal. With everything turned OFF the 
fuse should not blow. Of course the other way would be to check between the 
positive cable and chassis ground with an OHM meter. If you read more than 6 
OHMs (or so) you would probably be oksy to hook up the battery. 
Good luck with your E-type and drop by the BRIT_CAR echo also and tell us 
about it.
