2. Dichlorobenzol. — For this specimen I was indebted to 

 Dr. Hugo Mailer, who prepared it by his well-known process 

 of chlorination, which consists in treating hydrogenated bodies 

 with chlorine in presence of iodine. It was crystallized twice 

 from naphtha, and four times &c. (A 4 &c) from alcohol. 

 Dichlorobenzol melts very suddenly.
