This shows that the phenols and aldehydes (1 to 8) are at least 

 1 00 times more poisonous for the organism than absolute ethyl alcohol; 

 the aldehydes, ketones, and terpenes (9 to 14) 20 to 100 times, the 

 terpenes and ketones (15 to 20) 10 to 20 times, the esters (21 to 24) 

 5 to 10 times, and the alcohols up to 5 times more, or as in the case 

 of methyl alcohol, less poisonous.

Bornyl valerianate. In recent times O. Engels 1 ) has used 

 bornyl valerianate in numerous cases of neurosis of the most varied 

 character, including that of children, and he has been able to confirm 

 its excellent effect on which L. Hirschlaff 2 ) had already reported. 

 It is especially useful in traumatic neurosis, hysteria, neurasthenia, 

 epilepsy, nervous disorders of the stomach, and also in gynaecological 

 cases. It may be mentioned particularly that it stimulates the appetite, 

 and is free from all disagreeable secondary symptoms. 



Menthyl valerianate. As already mentioned by us in our last 

 Report 3 ) menthyl valerianate has been found to be an excellent 

 prophylactic against seasickness. K. Kopke 4 ), in a treatise on seasickness, 

 recommends this preparation on the grounds that ■ — though not ab- 

 solutely infallible, — it yet rarely fails to act. In the early stages 

 of the sickness it is best taken in 10 to 15 drops on a lump of sugar. 

 If this dose should not have the desired effect, it may be repeated 

 after half an hour, with observation of the strictest diet. 



Menthol. Contrary to his earlier statement, M. Bial 5 ) has after 

 later experiments established, that in the bile of dogs and cats, when
