 quantity, or part eclf^jfed as it i*! called in 

 altronomy, i^ me^fured by a line f r arc 

 paffing from the moon's fouthern limb to 

 the northern extremirv of the eirth's 

 fh .dow, wiien the moon's latitude is 

 north ; but if it be fouth, the line is 

 mea uied from the mithern limt) to the 

 fouthern extremity "f the ftndov. Tiie 

 line which me-lur-rs this quantity is a 

 perpendicular to :he moon's puh or orbit, 

 and v>a(rc- through her ce;)tre and alfo

 thcrefoit /aid, that i' an ecHpfe of the 

 moon lo digits are eclipfed ; it means 

 tha" *' thf la digits in the mo.n are not 

 ■only 1 bi'cured by the earth's fhadow, but 

 that i.s extremity extends fo far beyond 

 the moon i limh, that 'he rli'iance between

To the Editor of the Monthly Magazine. 



SIR, 



IN a late excurfion to Ireland I obferv- 

 ed fime abufes whicli may perliaps 

 be made known without otFeuce to thofe 

 who have the power to correft them, 

 through the medium of your Maga* 

 zine. 



No'.withftanding the UMon, which 

 (hould render the palling and repafling 

 between Great Briiain and Ireland a» 

 (imple as ,?oing from one county to an- 

 other, paQengers are pl.<gued witli the 

 forms and hindrance of Cuftom-Iloule 

 • entries on landing at either fhore, and 

 with the de'.eftabie rapacity of a gang of 

 CultomHoufe ofhcers. 



Another circumftance I am forry to 

 ,hive occafion to notice. The Captaiis 

 of fome of the Holyhead Packets who 

 are or ou^ht to be chofen for their ni- 

 val (kill are not unfrequently abfent (Voni 

 their duty; and during the heavy gales of 

 eafteily wind in OiStobsr laft, when five 

 packets '•■■ ere on the Dublin fide, three oi 

 the Captains were en this fide of the 

 Chani^cl. One of the pickets which fiiled 

 during the g^le witrtout hei Caiitain, got 

 foul ot the pier clole under Dublin light 

 lioufe, ind the cre«r were in the utmo(l 

 confufion, ail commanding. 



I failed from Dublin not long after iri 

 oneof thetn without a Cap:ain, and found 

 it difficult to afcertain who had the com- 

 mand ot the veffcl. 



In going to the northward through 

 Beifaft, I found that in order to crofs at 

 Donaghadhee a palfport from the Cuitom' 

 Houl'c was reqiiilite. 



Why are thefe diftini51ions kept up ? to 

 pafs from Holyhead co Dublin no padpo; t 

 is required, and yet to gu from the North 

 of Ireland to Port Patrick it mult be ob- 

 tained. If an Union is intended, eveiy 

 thing that reminds Ireland of her fuffjr. 

 ings Qiould furely be obhtcrated. The 

 Iriili now fay, it is " Union and H'j 

 Union." 



As I am complaining I will mention 

 one or two circumlfances ni~re. At cer- 

 tain times nf the tide, the port of Holv- 

 he.id is I'.) incoiiveniesit for getting on 

 boaid a veiTcl, that the only way of reach- 

 ing a boat is to walk through the water 

 pr climb ovt-r flippery lock.s, .'V. proper 

 whaif or furticiciit jetty ouglii to be budt 

 h^'f the accominidation ui tiie publir, at a 

 place trom wliich packeti are appointed lo 

 fail fix diys ill the week.
