3. Although less tolerant than clove oil towards the presence of water 

 in alcohol, liquid terpineol agrees with 90% alcohol. Sections 

 or membranes may be transferred direct from 90%, and if necessary 

 even from 80% alcohol into terpineol. 



4. It is miscible in any proportion with benzene, xylene, §c. 



5. It is considerably cheaper than eugenol or oil of cloves. 



6. Its index of refraction (n D20O 1,481 to 1,484) is decidedly lower than 

 that of clove oil. 



7. It has no acid reaction; carmine stainings are preserved in it ex- 

 cellently, and alum-haematoxylin stainings do not appear to fade 

 easily in it. 



A drawback of terpineol is that collodion is practically insoluble in it. 



Thiosinamine. From a publication by Vejux Tyrode 1 ) on the general 

 action of thiosinamine it appears that this substance, if administered in 

 sufficiently large doses, is able to produce serious disturbances in the 

 assimilation, causing a decrease in the weight of the body, and an in- 

 crease in the separation of urea. From the general symptoms, thiosinamine 

 appears to act destructively upon protoplasm, from which caution in the 

 clinical application of this remedy is indicated. 



Thymol. As we have already stated in our last Report, we have very 

 considerably increased our installations for thymol manufacture. In spite 

 of this we were hardly able to accumulate any stock during the period 

 under review, as the principal portion of our production was sold in ad- 

 vance. It goes without saying that the prices of thymol have left much 

 to be desired, for as soon as the working arrangement between the prin- 

 cipal manufacturers had been dissolved by mutual consent, the thymol 

 trade relapsed into the familiar old price-cutting. Only recently we heard 

 of quotations at about c4t 9.— per kilo(!). The raw material (weedseed) 

 has recently advanced by about 15%, but some time will probably elapse 

 before this increase in value finds a corresponding expression in the 

 quotations of thymol. 



Vanilla. H. Gautier and A. Kling 2 ) have determined the vanillin-content 

 of several samples of Tahiti vanilla of good quality and have discovered 

 that this variety of vanilla, when in moist condition, contains less than 

 1% vanillin.
