to be a pure Compound and to consist of C, II, N, S, P, Na, but some more 

 recent work would indicate that it is really a mixture of kephalin with 

 inorganic salts and various organic substances, cerebrosids, sugar, etc. 

 (Maclean). The work of Meyer and Terroine indicates it to be an absorp- 

 tion compound, which can be made from acid albumin, lecithin and glucose 

 in acid alcohol solution. 



According to Aufrecht and Dresing the whole gland yields 23.73 per 

 cent dry residue and of this 3.77 per cent is sulphur. In the human body 

 only the epidermis and horny structures gave such high S content. These 

 authors thought the suprarenal glands might have some relation to S 

 metabolism. 



No distinctive protein has been found in the suprarenals and these 

 proteins have as yet received only slight attention. Nabarro claims that 

 several nucleoproteins, globulins, etc. are present (Nabarre). Various 

 xanthiii bodies, hypoxanthin (Holm), xanthin, 1-methyl xanthin, prob- 

 ably epiguanin and adenin were reported by Okerblom. Jones and 

 Whipple obtained a nucleoproteid, but it yielded no xanthin, hypoxanthin 

 or epiguanin. 



The suprarenal cortex oxidizes salicylaldehyd, but this power is lost by 

 boiling and Jacoby(fr) attributes the action to an aldehydase. Croftan 

 has found that the suprarenals can exert a marked diastatic action and at- 

 tributes it to a ferment.
