The prize question proposed in the year 1 800, in regard 

 to prevailing diseases, to which no answer has been given, 

 is again proposed to be answered before the 1st of October 

 1805, with the usual prize: 



'f What are the reasons that the diseases which pj-cvail 

 at present among the inhabitants of Holland, at the difTer- 

 ent seasons of the year, are not so simple as in former 

 times? that is, do they arise from sources of an infectious, 

 bilious, or slinjy kind, or from several other causes com- 

 t)ined ? and what is the best method of distinguishing with 

 certainty, at the commencement of these disea,ses, which of 

 the above causes has the ascendency? and what is the best 

 method of cure?" 



The following question was proposed in the year ISC2, 

 to be answered before the 1st of October 1804: 



"■ What are the causes that Holland, about the begin- 

 ning of the seventeenth century, was so much distinguish- 

 ed over other countries by the great number of its writers, 

 original poets, and men of real learning ; and at the same time 

 produced in the course of that century so many celebrated 

 painters, though the number of these has been gradually 

 decreasing ever since? and what means of revivmg the arts 

 and sciences may be discovered by researches respecting 

 these causes ?" 



Another question proposed in the year 1799 was repeat- 

 ed in 1802, \yith a double prize, to be answered before the 

 1st of October 1804 : 



" As the difference of opipions which prevail among 

 physicians respecting the so called pathologia InimoraUsy 

 has an influencic not only on physiological researches, but 

 on the state of the medical science, the society requires 

 that the following points may be determined by more ac- 

 curate examination ;
