[meteorite-list] Meteorite numbers

[John Birdsell]

Hi Matt and list. I'm not an expert on the topic, but I think that part 
of the problem may also be that meteorites such as those belonging to 
the HED group are quite heterogeneous. If one sample contains a slightly 
higher diogenite component it may come back as a howardite while a 
sample with a lower diogenite component may come back as a eucrite. I 
would imagine that two samples from the same stone could conceivably 
come back with a different classification. If anyone can comment on this 
and correct me if I'm wrong I would appreciate it!


Cheers


-John
