edge of the shell being directed downwards. As they move through 

 the water they partially expand and close the valves of the shell. 

 Older and larger individuals are olivaceous, and are fond of lying on 

 their sides in the sand at the edge of the pond, now and then spinning 

 round and round by means of their protruded tail. The adult of 

 Kroyer's shield-shrimp, as it may be called, keeps in deep water, and 

 is voracious and predatory, not confining his attention to small things 

 in the water, but even feeding on drowned dragon-flies." — P. 121. 



Let us now pay a visit to the Korea, that terra incognita of distant 

 Europeans, that square block of land that seems in our maps to hang 

 down between the Yellow Sea and the Sea of Japan, and with the 

 natives of which the doctor appears to have been pleased, notwith- 

 standing the somewhat discouraging impression made by the first 

 interview. " We found them kinder than was warranted by their 

 looks." One of their customs, noticed by the previous traveller, 

 Hamel, Mr. Adams thinks worthy the imitation of Christian nations, 

 and that is the care which sons take of their fathers. " When a father 

 is four score years of age, he declares himself incapable of managing 

 his estate and resigns it to his children. Then the eldest, taking 

 possession, builds a house at the common expense for his father and 

 mother, where he lodges and maintains them with the greatest respect." 

 This is doubtless commendable in both father and son, but it has 

 another teaching which our doctor seems rather to have overlooked; 

 and that is that the prolongation of human life to four score years is 

 spoken of as an occiu"rence that needs no comment. But I must 

 allow the doctor to discourse of his doings in his own pleasant 

 manner, and not introduce reflections of my own. 



" One afternoon, while lying at anchor in the safe and pretty port 

 of Mah-lu-san, one of the Korean group, there was a seining party, 

 which I accompanied. The day was lovely ; the whole face of the 

 country was bright and smiling ; the barley was ripe in the fields, the 

 hills were covered with a varied green, and the little rippling waves 

 of the clear water of the bay were dancing in the sun. Stretching far 

 away to the north and to the south were groups of dark-blue islets, 

 rising mistily from the surface of the sea — glimpses of that mysterious 

 Archipelago, among the unknown islands of which I cruised in by-gone 

 years. The sea was covered with large picturesque boats, which, 

 crowded with Koreans in their white fluttering robes, were putting off 

 from the adjacent villages, and sculling across the pellucid water to
