structed too recently to admit of any results being obtained

Medical Science. 



The London Committee on the Sounds of the Heart stated 

 the circumstances which prevented the preparation of their re^ 

 port, and announced that it will be ready at the meeting in 1839. 



" The Committee have been engaged almost daily for several 

 hours during the months of June and July, in prosecuting the 

 researches for which they were appointed, and have obtained 

 many interesting results, particularly in relation to the sounds 

 of the heart and arteries as signs of disease. These results were 

 to be presented at the present Meeting of the Association; but 

 the death of a colleague having prevented the member who was 

 to draw up the report from completing it, the Committee are 

 obliged to postpone it to the next meeting, when they trust 

 that it will be made still more worthy of the attention of the 

 Medical Section of the British Association." 



Dr. WilUams expressed his hope of being able to present a 

 report on the Physiology of the Lungs and Bronchi m 1839.
