8 Proeess for Dyeing the Airianople or Turkey Red. 



From all this it results i 



1. That it is very ill judged to proscribe the medicinal 

 use of waters distilled from plants called inodorous. 



2. That these waters have decidedly constant properties. 



3. That these properties are the more decided, the more 

 they contain of the aroma of the plant. 



4. That the proper method is to cohobate upon fresh 

 plants thrice or even four times the produce first distilled. 



5. That the waters thus procured ought always to be pre- 

 served in vessels not capable of being traversed by the rays 

 of light. 



6. That it is necessary to clear these waters from the flaky- 

 deposits which appear soon after distillation. 



7. That, considering the short duration of these waters in 

 a state of perfection, it is indispensably necessary for the apo- 

 thecary to renew his stock of them once a year. 



8. Lastly, that it is desirable that physicians, profiting 

 by the facts which have been now laid before them, would 

 turn their attention to the discovery of new ones. Their 

 experiments on this subject will be extremely useful, because 

 they will contribute to destroy the prejudice which main- 

 tained, that, waters distilled from inodorous plants having no 

 action upon the animal ceconomy, their use ought to be 

 nroscribed. 



II. Process for Dyeing the Adr'wnople or Turkey Tied, c* 

 practised at Astracan. By Professor Pallas : Icing d 

 Supplement to his former Publications on that Art*. 



One of mv friends, the proprietor of a dye-house at Astra- 

 can, communicated to me the most accurate details of the 

 process for dyeing Turkey red. On Saturday, after the cot- 

 ton yarn has undergone those preliminary preparations al- 

 ready mentioned *, it is immersed, for the first time, in fish 

 grease or fish oil, which is made into a lather by a solution 

 of soda : heaped up in this bath, where it heats sensibly, it
