zaldehyde, that is substances of an aldehyde character, do not 

 give the reaction; fifth, if formadehyde is present together with the 

 chloral, the reaction is not interfered with provided the test is 

 done at room temperature. The technique follows: 



To one c.c. of distillate are added 6 drops of saturated resorcin 

 and one c.c. of saturated sodium carbonate solution or less if 

 only traces of chloral are present. Let stand for one half hour, 

 then dilute by adding 10 c.c. of water. A beautiful green fluor- 

 escence results. In cases of extremely small quantities of chloral, 

 viewing by direct sunlight against a black, glossy background is 

 of great advantage. Any development of color or fluorescence 

 after many hours is of no consequence. 



A series of 66 distillates from cases of suspected poisoning were 

 examined by the above two described methods, with the following 

 result:
