End of Spectrum. 
None of the powerful bands of Carbon are here, as they are eminently in Hydrochloric Acid. 
The Hydrogen lines here are weak as impurities only, compared with what they are in Hydrochloric Acid, where they are 
a constituent, But the Chlorine lines are far stronger here. 
i oat however, is peculiarly absent from all the other tubes, absolutely too if tested by its chief line, the close double 
The column of 6-inch spark, or high-temperature, Chlorine lines is derived from THALENS, Huaerns, and others who have 
so observed, and is curious for both its agreements and disagreements with my low-temperature, small spark, spectrum lines.
