PRASE DISCOVERED IN SCOTLAND. 
We understand that Dr. MacCulloch has recently discovered 
prase in Scotland, and that it is found in Loch Hourn forming 
veins in a gneiss which contains actinolite schist. ‘To this sub- 
stance it is known to be indebted for its colour. Our mineralo- 
gical readers will be glad thus to know that they may increase 
their collections of British minerals by a variety of quartz which 
is no where very common. It may probably not be known to 
them that the ‘* prase’”’ mentioned in Jamieson’s Mineralogy is 
a quartz penetrated and coloured by chlorite, a substance very 
common in Argyllshire, but essentially distinct from the mineral 
in question. sate NRL 
TAR LIGHT FOR STREET LAMPS, 
It is stated in an American newspaper that Professor Hare, of 
William and Mary College in Virginia, has invented an appara- 
tus for burning tar instead of oil, in lighting cities and manufac- 
tories.—It is said that tar burned in this apparatus gives a strong 
and clear light; and it is computed, that four or five barrels of 
tar will serve a lamp for one year, and will give eight times the 
light of a common street lamp. The following is given in the 
Union as a description of the apparatus :—It ‘ consists of a foun- 
tain reservoir to hold four or five pounds of tar to supply the lamp 
at a uniform height, and a lantern with a draught pipe attached 
to it.—The lamp presents at one end a cylindrical mouth for re- 
ceiving the pipe of the reservoir; at the other end a cylindrical 
cup, in which the tar is ignited, the flaine being drawn up through 
a central hole in the bottom of the lantern so as to occupy its 
axis in passing to the draught pipe. All the air which supplies 
this is made to meet in the same axis, and thus to excite the 
combustion.”
