Vlll PREFACE. 
sailed with Mrs. Getting for Europe, where they passed 
the summer. His presence with us during that time 
was most fortunate, for it so happened that the only 
serious cases of illness we had among us occurred before 
he left, and his medical advice and care were of great 
service. I lost the assistance of Mr. Anthony, and Mr. 
Allen also, early in the expedition ; their health, always 
delicate, obliging them to leave for home. With these 
exceptions, our working force remained intact, and I am 
happy to state that every member of the party returned 
in safety to the United States.* 
No sooner was the Brazilian Expedition known to the 
public, than I received a letter from Mr. Allen McLane, 
President of the Pacific Mail Steamship Company, offer-

since it was of some years' standing, was no doubt aggravated by the hot 
climate. His great desire to accompany me led him, against my advice, 
to undertake a journey which, in his case, was a dangerous one. He suffered 
very much during our stay on the Amazons, but I could not persuade him to 
leave his work; and in the following pages it will be seen that his industry 
was unflagging.
