de Prato lias, however, lately aflerted *, in oppofition to 

 M. Haflenfiatz, that fnow is not oxygenated : ill, becaufe fifli 

 which lived very well in common water, did not live in recent 

 fnow water, but died in a fhort time: 2d, becaufe fnow water 

 expofed to the aftion of light did not fuffer oxygen gas to be 

 difengaged. lie afcribes therefore the ftidden death of fifb, 

 and the non-produ6tion of oxygen by light, to the want of 

 that fubdance in fnow water. M. Haflenfratz has obferved^ 

 in anfwer to thefe obje6lions, that animals may die either 

 through the want or by an excefs of oxygen, as well as by the 

 '■want or an excefs of nourifl)mcnt, and that a mean propor- 

 tion of both are necefl'ary for the prefervation of life and 

 health : that all oxygenated fubftances do not difengage their 

 oxygen on being expofed to the light; and that when it is dif- 

 engaged, they fuffer only the excefs to efcape — another portion 

 remains which cannot be taken from them by that agent. Dr. 

 Carradori," fays M. Haflenfratz, " does not deny the refults 

 of the experiments I have announced ; he only thinks they 

 are not conclufive, becaufe fifli do not live in recent fnow 

 water." He therefore promifes, as foon as he can procure 

 fnow water, to repeat Dr. Carradori's experiments; to vary 

 them, and make new ones, in order to prove in the moll 

 politive manner the exiftence of oxygen in fnow , and to de- 

 termine the caufes of the phenomena which feeni to belong 

 to it cxclufivcly.

We are informed byProfcflbrBeckmann, that the Chamber 

 of the Mark at Berlin has lately been at great pains to pro- 

 mote the manufa<5laring of fugar from plants indigenous in 

 Germany. Some experiments were made for that purpofe 

 with the juice of tb.e maple, which was refined in a fugar 

 bakehoufe, and found to be equal to loaf fugar. Profeffor 

 Beckmann, who faw fpeciniens of it, fays, it has been found
