From this state of languid indifference Mr Werne was suddenly and pleasurably roused by intelligence that a second expedition was fitting out for the White Nile. He and his brother immediately petitioned the Bascha for leave to accompany it. The desired permission was granted to him, but refused to his brother. There was too much sickness in the camp, the Bascha said; he could not spare his doctor, and lacked confidence in the Italian, Bellotti. The fondly-attached brothers were thus placed in a painful dilemma: they had hoped to pursue their wanderings hand in hand, and to pass their lives together, and loth indeed were they to sunder in those sickly and perilous regions. At last they made up their minds to the parting. It has been already recorded in Mr Werne's former work, how, within ten days of their next meeting, his beloved brother's eyes were closed in death. In various respects, Mr Werne's _Feldzug_ is one of the most curious books of travel and adventure that, for a very long time, has appeared. It has three points of particular attraction and originality. In the first place, the author wanders in a region previously unexplored by Christian and educated travellers, and amongst tribes whose bare names have reached the ears of but few Europeans. Secondly, he campaigns as officer in such an army as we can hardly realise in these days of high civilisation and strict military discipline,--so wild, motley, and grotesque are its customs, composition, and equipment,--an army whose savage warriors, strange practices, and barbarous cruelties, make us fancy ourselves in presence of some fierce Moslem horde of the middle ages, marching to the assault of Italy or Hungary. Thirdly, during his long sojourn in camp he had opportunities such as few ordinary travellers enjoy, and of which he diligently profited, to study and note down the characteristics and social habits of many of the races of men that make up the heterogeneous population of the Ottoman empire. Some of the physiological and medical details with which he favours us, would certainly have been more in their place in his brother's professional journal, than in a book intended for the public at large; and passages are not wanting at which the squeamish will be apt to lay down the volume in disgust. For such persons Mr Werne does not write; and his occasional indelicacy and too crude details are compensated, to our thinking, by his manly honest tone, and by the extraordinary amount of useful and curious information he has managed to pack into two hundred and seventy pages. As a whole, the _Expedition to the White Nile_, which contains a vast deal of dry meteorological and geographical detail, is decidedly far less attractive than the present book, which is as amusing as any romance. We have read it with absorbing interest, well pleased with the hint its author throws out at its close, that the records of his African wanderings are not yet all exhausted.
