X HIS volume contains, I. Ciirfory Remarks, moral and political, on Party Prejudice. 

 By Saniuel Argent Bardfley, M. I). — 2. Extraordinary Fads relating to the Vifion of Co- 

 lours; with Obfervations. By Mr. John Dalton. The intelligent author of this valuable 

 paper is himfelf the fubjeit of many of his obfervations refpecling the peculiarity of his per- 

 ceptions of colours. This Memoir confifts of an account of his own vifion ; an account of 

 others whofe vifion has been found fimilar to his ownj and obfervations refpedling the 

 probable caufe of the peculiarities he defcribes. The folar fpedrum, formed by the prifma- 

 tic difperfion of light, exhibits to him only two, or at moft three, colours, which he fliould 

 call yellow and blue, or yellow, blue, and purple. This yellow comprehends the red, 

 orange, yellow, and green of others ; and his blue and purple coincide with theirs. He 

 enters minutely into the requifite comparative obfervations on the feveral colours refpeft- 

 ively as they afFeft his organs of fight. Pink appears, by day-light, to be fky-blue a little 

 faded ; by candle-light it affumes an orange or yellowifh appearance, which forms a ftrong 

 contrail to blue. Crimfon appears a muddy blue by day ; and crimfon woollen yarn is 

 much the fame as dark blue. Red and fcarlet have a more vivid and flaming appearance 

 by candle-light than by day-light. There is not much difference in colour between a ftick 

 of red fealing-wax and grafs by day. Dark green woollen cloth feems a muddy red, much 

 darker than grafs, and of a very different colour. The colour of a florid complexion is 

 dufky blue. Coats, gowns, &c. appear to Mr. Dalton, and the other individuals he men- 

 tions, frequently to be badly matched with linings, when others fay they are not. On the 

 other hand, they fhould match crimfons with claret or mud ; pinks with light blues ; browns 

 with reds ; and drabs with greens. In all points where they differ from other perfons, the 

 difference is much lefs by candle-light than by day-light. Mr. Dalton, by various obferva- 

 tions, fhews, almoft beyond a doubt, that this afFe£lion of the eye is caufcd by fomeofthe 

 humours,' probably the vitreous, being coloured by fome modification of blue. — 3. An En- 

 quiry into the Name of the Founder of Huln Abbey, Northumberland, the firfl in England 

 of the Order of Carmelites ; with Remarks on Dr. Ferriar's Account of the Monument in 

 the Church of that Monaflery. By Robert Uvedale, B. A. of Trinity College, Cambridge. — 

 4. On the Variety of Voices. By Mr. John Gough. It is a fadt which continually prefents 

 jtfelf to our obfervation, that founds differ from each other in other refpedls as well as in 

 mufical tone and their intenfity. The oboe, the violin, and the flute, however perfedly they 

 maybe made to agree in thefe refpcfts, are ever found to differ in fomething which may be 

 called the charader of the tone itfelf. The author of this paper conceives that the variety 

 of human voices is of this laft kind ; and, in his reafoning on the philofophy of found, he 

 confiders every tone as compounded. So that the fame cotemporaneous founds which are 

 heard in the bell, though praflically confidered as if it emitted the fundamental note only, 

 being conceived to exift in all other tones, thefe will be found to differ according to the 

 number, the nature or relation, and the intenfity of their component parts. That circum-
