295 Apparent Diminution of Weight in certain circumstances, 



7th and 8th. Lifted with the lungs kept inflated, and experienced 

 more difScuky. 



9th and 10th. Repeated fourth with same result. 



11th and 12th. The bearers only used the prescribed method, the 

 load took no part other than to give signals, result same as fourth trial. 



13th and 14th. Having changed the load repeated first. 



15 and 16th. Repeated fourth, same result. 



17th and 18th. Repeated eleventh and twelfth, same result. 



19th and 20th. Similar to fourth, except that the prescribed process 

 was intentionally neglected by one of the bearers, unknown to the 

 others, no difference in consequence was observed by the others, and 

 but very little by himself. Except therefore, so far as the one bear- 

 er was concerned, the results were similar to that of the fourth trial. 



21st and 22nd. Repeated fourth with same result. On these tri- 

 als the load was placed on a board and the strength of the bearers 

 applied to the board. 



23rd. Repeated first, load still on the board. 



24th and 25th. Same as twenty first and twenty second, same re- 

 sult. 



26th, 27th and 28th. Load still on the board, repeated seventh 

 and eighth with same results. 



29th and 30th, Having changed the load, repeated the first. For 

 this and the remaining trials, the load was kept on the board. 



31st and 32nd. Repeated seventh and eighth, same result. 



33rd. Repeated first. 



34th and 35th. Repeated fourth, same result. 



These trials w^ere made at three different times with the assistance 

 of three different parties. At each time it was found necessary af- 

 ter half a dozen trials, to intermit for a few moments, as the wrists 

 of the bearers became quite tired. The following conclusions were 

 deduced. 



1st. When the lungs are fully inflated and the act of lifting and 

 that of expiration is carried on simultaneously, the load is apparently 

 lightened. 



2nd. No other situation of the muscles of the chest will give the 

 same result. 



3rd. The result is independent of the co-operation of the person 

 lifted and is equally perceived with an inactive weight and by conse- 

 quence with an inanimate weight.
