SOCIETY OF SCIENCES OF HAARLEM. 
Tae following questions in the Physical Sciences have been 
proposed by this Society for competition previous to the Ist of 
January 1820: 
3. How far it is actually demonstrated that the fumigations 
by oxygenated muriatic gas after the manner of Guyton have 
served to prevent the spread of contagious maladies? What are 
the contagious maladies in which the effect of this gas deserves 
to be tried, and what ought to be principally observed in such 
experiments? Is there any reason to expect a more salutary 
effect, in the prevention of contagion, from any other mean hi- 
therto employed or proposed ? 
4. What are we to regard as distinctly proved in respect of 
the gastric juice of the human body, and its influence in the di- 
gestion of food? Is its existence sufficiently proved by the-ex- 
periments of Spallanzani and Senebier; or has it been rendered 
doubtful by the experiments of Montégre ? What is it that com- 
paratiye anatomy, and principally the opening of the stomach of. 
animals killed, either after fasting, or in a short time after having 
taken food, have rendered probable in this respect? And in the 
case of the existence of the gastric juice in the human body being 
tegarded as a fact perfectly established, what ought we to avoid, 
in order not to impair its effect in the process of digestion? 
5. As the new mode of distillation which some years since . 
was originally practised at Montpellier, and has been sincé 
adopted and improved in the south of France, according to which . 
the substances from which spirituous liquors are extracted are 
not immediately exposed to the action of fire, but heated by 
steam—a process which is not only more ceconomical than the 
ordinary method, but which has this additional advantage, that 
the spirituous liquors produced by it are of a purer and a more. 
agreeable taste—the Society desire to know ‘* What is the 
best apparatus for extracting, according to this method, with the 
greatest profit, the purest spirituous liquors from grain, as wine 
is drawn from the vines of France ?”” Ne 
The prize offered to those who, in the judgement of the So- 
ciety, shall give the best answer to any of these questions, is a 
gold
