ON INTESTINAL SECRETION. 



339 



Your Committee are unwilling to close this Report without alluding to the 

 advantages which may incidentally accrue to mathematical science by even 

 a partial adoption of the modifications here suggested. Any thing which 

 tends towards uniformity in notation may be said to tend towards a common 

 language in mathematics ; and whatever contributes to cheapening the pro- 

 duction of mathematical books must ultimately assist in disseminating a 

 knowledge of the science of which they treat,

Second Report of the Committee appointed to investigate Intestinal 

 Secretion. By Dr. Lauder Brunton and Dr. Pye-Smith. 



The experiments carried out by your Committee last year (vide p. 54 of 

 Report for 1874) were directed, first, to ascertain the relative effect of 

 various neutral salts locally applied to the small intestine ; secondly, to de- 

 termine the inhibitory action of drugs injected into the circulation in modi- 

 fyijjg the above effects ; and thirdly, to ascertain the precise manner in which 

 the intestinal secretion is affected by the nervous system. Referring to the 

 Appendices to our last Report for the contributions your Committee were 

 able to make towards the solution of the first two of these problems, our
