OK ALBUMEN AND OTHER ANIMAL FLUIDS. 13 



laborious to turn (I communicated this to Mr. Singer, when 

 the same improvement occurred to him.) I am of opinion, 

 that it is possible on this principle, to make one single 2- or even quad* 

 foot plate machine act equal to four cylinders, or to two rui> * 

 double plate machines. If I succeed, I shall be able to 

 equal the power of the large machine, which I made at 

 Haarlem ; and that too with one plate only and of much less 

 diameter. If this contrivance should be applied to that 

 machine, the effect must be astonishing; perhaps equal to 

 the production of effects similar to the powers of the vol- 

 taic battery. In conjunction with Mr. Singer, I am now 

 engaged in a series of experiments on this subject; should 

 our success be equal to the expectations I have formed, the 

 results will be of the highest interest to the progress of elec- 

 trical science. When we have completed these experiments, 

 we shall take an early opportunity of communicating them 

 to the public, through the medium of your justly esteemed 

 Journal.

 intervertebral fluid of the spalus maximus, an account of on mucus U** 1 

 which is annexed to Mr. Home's paper " On the nature of 

 the intervertebral substance in fish and quadrupedsf," led 

 me to undertake a series of experiments on mucus, in order 

 to examine the properties of that secretion in its pure state,
