cross-shaped Pur/ionium connitum, originally describfd by (Jmcliii in 

 the last coiitury, but quite unknown to niodorn botanists." 



From Dinjj^-hu, where much trouble was experienced from tho 

 Chinese otiiciiJs, the party proceeded into Ala-shan — "a wild and 

 barren desert, inhabit^^'d by Uliub Mongols, which forms the southern 

 part of the high plateau of the (iobi." Here, at Din-yuang-ing, a 

 hospitable reception was met with from the ruling Prince, a tribu- 

 tary of tho Chinese Empire. After a fortnight's stay in the Ala- 

 shan mountains, and exploration of their fauna and Mora, it was 

 decided to return to I'ekin in order to obtain fresh supplies of money 

 and necessaries for a new journey. 



In his second volume Colonel Prejevalsky gives lis an account of 

 his second expedition from Pekin,in 1872. On this occasion he left 

 Kalgan on March 17th, and returned by the same route to Alashan, 

 where the prince of Alashan and his sons received him with open 

 arms, and were in fact very unwilling to let him go again. After 

 some delay, however, he succeeded in being allowed to join a caravan 

 of Tangutans and Mongols returning from Pekin to the temple of 

 Chobsen, situated in the province of Kan-su, only five days' journey 

 from Lake Koko-nor, and arrived there early in July. After spending 

 several months in making zoological and botanical observations in 

 the hitherto unexplored mountains of Kan-su, another start was made, 

 and the much-desired lake reached on the 25tli of October. " The 

 dream of mj* life," says our author, '' was thus accomplished, and 

 the object of the expedition gained." 



AVe need not follow our adventurous traveller in his further 

 wanderings. Sullice to say that in a winter journey from Koko-uor 

 he finally penetrated to the banks of the Upper Yang-tse-kiang, 

 only about 27 days' journej* (or 500 miles) from Lhassa, where want 

 of funds was the sole obstacle that stopped his further progress. 

 But we strongly recommend every naturalist to read Colonel Preje- 

 valsky's narrative for himself; for a more interesting journal has 

 never come under our penxsal. Zoological, botanical, and ethnolo- 

 gical notes respecting these unknown regions are interspersed through- 

 out the volumes, and render them especially attractive to those en- 

 gaged in the study of these sciences. 



Colonel Prejcvalsky's third volume, which in the original Kussian 

 gives a complete account of his biological discoveries, does not form 

 a part of the present edition. But we believe this also is being 

 translated by a person fully competent to the task, and will shortly 

 be given to the English public in another form. P. L. S.
