 Partly on account of the exhausted condition of his health, and also 

 for the pur^DOse of i)reparing for his long-x3lanned expedition to 

 Kenia, the northern rival of the Kihma' Ndjaro, Hildebrandt re- 

 turned to Europe in August, 1874. However, in the early iDart of 

 the following year, he began his second expedition, leaving Aden, 

 which he reached in February 1875, first for Meitli in the pro- 

 vince of Habr-Gehardyis-Somal. From here he visited the Serrut 

 Mountains, (about 2000 m.) in which he found, besides Buxus 

 Hildebrandtii, Baillon, observed before in the Ahl Mountains,
