his observation, a difference of 2° Fahr., viz. from 73" to 75« Fahr., 

 when the ambient air was 72° Fahr. 



This communication called forth some remarks from Dr Spittal 

 and Mr Edmonstone, on observations they had themselves made on 

 the chameleon ; from Mr Dick on the tongue of that animal ; and a 

 notice from Dr Allen Thomson, of some experiments made by him 

 on the change of colour observable in the cuttle-fish. 



Dr Allen Thomson then exhibited to the meeting a series of 

 preparations made by Dr Sharpey and himself, of injections of 

 the lacteal and lymphatic absorbent vessels of the seal, por- 

 poise, turtle, and man — preparations which appear to them to 

 support the conclusions of Professor Panizza of Pavia, in opposi- 

 tion to the opinion of Fohmann, Lippi, and others, as. to the non- 

 existence of numerous communications between the absorbent? 

 and veins. It was resolved that the connexions of these two sys- 

 tems of vessels should be proposed to the General Committee as a 

 subject for experimental .inquiry. 



Section F. — Statistics. 



The Statistical Section having met at eleven, a discussion arose 

 on the paper presented by Mi* Heywood yesterday, in which seve- 

 ral members from the large manufacturing towns in England, and 

 from the mining districts of Cornwall and Wales, took a part. 



The discussion turned principally upon the advantages of Sunday 

 and Infant Schools, especially as shewni in the reaction on the ha- 

 bits of the parents of children attending them. Many instances of 

 this were stated to be within the knowledge of members present, 

 who had directed their attention to this subject. 



The possibility of ascertaining, by direct inquiry, the amount of 

 the earnings of the poorer classes was discussed, and the difficulty 

 of obtaining information of sufficient accuracy on this very impor- 

 tant head was strongly pointed out by the fruitless attempts which 

 had been made by the Statistical Society of Manchester, as also of 

 Dr Cleland in similar enquiries undertaken by him for the use of 

 Government. 



Mr Taylor and his brother undertook, in conjunction with the 

 Committee, to draw up a series of questions upon the condition and 

 habits of the mining population in Cornwall and Wales, from which 

 they hope to draw a complete account of the statistics of that clas8 

 for the next meeting of the Association.
