420 PHYSIOLOGICAL CHEMISTRY. 



water. Add 700 grams of concentrated ammonium hydroxide, 

 mix thoroughly and preserve the mixture in a glass-stoppered bottle. 



Millon's Reagent. 1 Digest i part (by weight) of mercury with 

 2 parts (by weight) of nitric acid (sp. gr. 1.42) and dilute the re- 

 sulting solution with 2 volumes of water. 



Molisch's Reagent. 2 A 15 per cent alcoholic solution of 

 a-naphthol. 



Molybdic Solution. 3 Molybdic solution is prepared as follows, 

 the parts being by weight: 



Molybdic acid i part. 



Ammonium hydroxide (sp. gr. 0.96) 4 parts. 



Nitric acid (sp. gr. 1.2) 15 parts. 



Moreigne's Reagent. 4 Combine 20 grams of sodium tungstate, 

 10 grams of phosphoric acid (sp. gr. 1.13) and 100 c.c. of water. 

 Boil the mixture for twenty minutes, add water to make the vol- 

 ume of the solution equivalent to the original volume and acidify 

 with hydrochloric acid. 



Morner's Reagent. 5 Thoroughly mix i volume of formalin, 45 

 volumes of distilled water and 55 volumes of concentrated sulphuric 

 acid. 



Nakayama's Reagent. Prepared fry combining 99 c.c. of al- 

 cohol and i c.c. of fuming hydrochloric acid containing 4 grams 

 of ferric chloride per liter. 



Neutral Olive Oil. 7 Shake ordinary olive oil with a 10 per 

 cent solution of sodium carbonate, extract the mixture with ether 

 and remove the ether by evaporation. The residue is neutral olive 

 oil. 



Nylander's Reagent. 8 Digest 2 grams of bismuth subnitrate 

 and 4 grams of Rochelle salt in 100 c.c. of a 10 per cent solution 

 of potassium hydroxide. The reagent should then be cooled and 

 filtered.
