has always formed a leading department in their Memoirs. I shall 

 here present }\ty readers with ibe contents of their Memoirs tor 

 )8J.% the hist published volumes, and give outlines of such papers 

 as are capable of abridgment, and suitable to the subjects discussed 

 in tl r Annuls fl^* Philosophy. 



1. On the velocity of the water, which, according to the expe- 

 riments hitherto nude with small wheels, is found proportional to 

 the rectangular shock. By Zach. Nordmark. 



2. On the determination of the timo, when the true anomaly is 

 given, and the orbit does not differ much from a parabola. By 

 S. A. Cronstrand. 



3. An easy method of determining the principal properties of the 

 curve line in which a body is drawn towards a given point by a 

 centripetal force, which is proportional to some function of the 

 distance. By N. J. Bergsten. 



4. Experiments in order to improve theoretical chemistry, and 

 to render its systematic arrangement subservient to a more perfect 

 chemical nomenclature. By Jac. Berzelius. 



5. Extracts from a table exhibiting the births and deaths in 

 Sweden during the years 1806—1810. By H. Nicander. These 

 t.'bS > ;ire too copious to be inserted here; but they deserve the at- 

 tention of those who are engaged in the interesting department of 

 poiivkvu arithmetic. The years included in them were very eventful 

 and very injurious to Sweden.

 ©f metallic points, galvanism may be produced of considerable 

 power and utility for medical purposes. By J. P. Westring.

 had been previously confounded with the rosa can'ma. The descrip- 

 tion is accompanied by a figure. 



8. An attempt to delineate the colours in nattial history. By 

 G. J. Biliberg. This is similar to the late publication of Mr. Syme,

 cuted. Biliberg delineates 80 colours, which he divides into 10 sets ; 

 namely, white, grey, black, blue, green, yellow, orange, red, 

 brown, and violet, or purple. For the sake of his Latin names, I
