The body is rapidly decomposed by exposure. It melts 

 gradually between 70° and 90° and becomes white at about 

 115°. It is decomposed by strong alcohol and by ether.

This was made by adding 60 g. of iodine to a hot saturated 

 solution of 20 g. of lithium chloride in dilute hydrochloric acid, 

 saturating with chlorine and cooling. A large quantity of 

 long, yellow needles was thus obtained. On evaporating the 

 mother-liquor in a desiccator larger prisms were deposited.

On exposure to the air the substance quickly deliquesces, 

 forming a yellow liquid. This gradually loses its color, finally 

 leaving a solution of lithium chloride. The body melts at 

 70°-80° and becomes white at about 180°. The crystals of 

 this compound were not measured. 



Crystallography. 



The crystallization of Csl 5 is triclinia By slow evaporation 

 of a solution in a desiccator, crystals were obtained which were 

 about 10 mm in diameter. Two crops were examined, in one of 

 which the habit shown in fig. 1 prevailed while in the second 

 the crystals were more highly modified like figs. 2 and 3.
