Profeffor Brera, whe was two years phyfician to this eminent 
naturalift. Two monuments are to be erected at the public 
expence to his memory; one in the Pantheon of Milan, and 
another within the precinéts of the Univerfity of Pavia. 
In the fame Number of the Philofophical Magazine we an- 
nounced alfo the death of Profeflor Lichtenberg, of Gottingen, 
on the 24th of February. Since that period a fmall work 
_ has appeared at Gottingen under the title of, Elogium Georgit 
Chriflophor: Lichtenberg, in conceffu Soc. Reg. Scientiarum re-= 
citavit A. G. Kajiner, 207°. d. Ap. 1799; from which we 
extract the following particulars :—Profeflor Lichtenberg was 
born on the 1ft of July 1744, at Oberamftadt, in Heffe Darm- 
ftadt. He was of a weakly conftitution from his birth, and 
applied himfelf very early to the mathematics and natural 
hiftory, in which he was greatly affifted by his two brothers, 
who were older. In the year 1763 he went to Gottingen, 
where he became the pupil and friend of Kaftner and Meitter, 
and attended the Lectures of the other profeffors. In con- 
_junétion with Erxleben he made fome obfervations on the 
earthquake of 4767; and remarked, in particular, that the 
_ fhock continued fix feconds ; while others, not accuftomed to 
“tathematical accuracy, extended its duration to a whole mi- 
mute. He delineated the courfes of the comets which had 
been oblerved; and it is remarked, that he poffeffed a great 
deal of patience for works of this kind. Profeffor Kafiner 
has now in his pofleflion a drawing by him, of the face of the 
“moon, where the fpots are marked in the order in which they 
enter the earth’s fhadow during eclipfes. In the year 1770 
he was invited to Gieflen; but he preferred Gottingen, where 
hie was appointed Profeffor Extraordinary. In the years 1772 
and 1773 he was commiflioned to determine, from aftrono- 
‘thical obfervations, the pofition of various places in his Bri- 
tannic Majefiy’s German Siates; and for this purpofe was 
fupplied, at the king’s expence, with a quadrant by Siffon. 
‘Tt 1776 he laid the ‘refult of this labour before the Royal 
Society, of which he had been elected a member two years 
before. -As repeated wifhes had been expreffed that Mayer's 
- Manufcripts might be publithed, Profeffor Kaftner put them 
fgpte the hands of Lichtenberg, who, affifted by Dietrich, 
publithed
