arranged at the opposite side, in such a way as to permit a definite 

 pressure to force the surface of the boards together. The spring 

 can be adjusted so as to increase or decrease, within considerable 

 limits of weight, the amount of force (weight) required to bring the 

 board surfaces in contact. In the opposed surfaces of the boards 

 platinum electrodes (plate and points) are so placed that perfect con- 

 tact between them is effected when the boards are brought together 

 and the circuit is closed. The electrodes connect with binding posts 

 on the hinged side. A small dry cell is used. The entire appa- 

 ratus, including bell attachment, may be placed on a surface 

 5x8^ inches. The bell employed directly with the apparatus is 

 a small one with delicate musical sound. Its ringing under a cage 

 during a metabolism experiment does not disturb the animal . It 

 is obvious, of course, that the apparatus can be connected with a 

 bell in a distant room. 



In the demonstration it was shown that the apparatus an- 

 nounced the deposit, in an ordinary urinary receiver placed on it, of 

 volumes of water less than 5 c.c. The apparatus may be adjusted to 

 announce a volume as small as 1 c.c. and may be made, in larger 

 sizes, to announce the deposit of masses of any desired weight. 



Various details of description that would show the particular 

 value of the apparatus in other respects will be given in the paper 

 soon to be published by Mr. Welker. 



5 1 (143). " Some observations on the presence of albumin in 

 the bile " : WILLIAM SALANT. 



The presence of albumin in the bile under pathological condi- 

 tions has been noticed by several observers. Thus, Lehmann, 1 

 who examined post-mortem bile from the gall bladder in 100 cases, 

 found albumin in nutmeg liver, fatty liver, and parenchymatous 

 hepatitis. Pouchet 2 found albumin in the bile of six patients that 

 died of cholera. Among recent observers may be mentioned 

 Brauer 3 who has reported similar findings in typhus and paren- 

 chymatous nephritis. Hallauer 4 analyzed the bile in a number of
