IO2 VEGETABLE SUBSTANCES. 



line deposit, in brown oily drops, or in the form of 

 ropy, semi-fluid masses, from which, after a while, 

 needle or staff-shaped bodies, or fine crumpled 

 threads separate. According to Meyer ' the hypo- 

 thetical matter called hypochlorin by Pringsheim 

 is identical with the chlorophyllane of Hoppe- 

 Seyler, 2 which is but a transformation product of 

 the green pigment of the living plant, and perhaps 

 also identical with the "crystallized chlorophyll" 

 of Gautier. 



It is insoluble in water, salt solutions, and dilute 

 organic or mineral acids. It is easily soluble in 

 ether, benzole, volatile oils and carbon bisulphide. 

 An aqueous solution of chloral dissolves the crys- 

 tals, leaving a drop which is soluble in alcohol. 

 Heat volatilizes it so that green cells, which have 

 been warmed to 50 C, give no trace of hypo- 

 chlorin when subsequently treated with hyrochloric 

 acid. When hypochlorin needles that have been 

 formed by the aid of this acid are heated in water 

 they lose their crystalline nature, and unite to 

 form oily masses of a greener hue.
