i'li,' completed Report contains Memoirs from seventy-six authors who, 
for the most part, are natives of Great Britain and her colonies, but 
scientific men of nearly all civilized countries are represented among the 
contributors. In addition to the authors whose names appear on the title-

Museum. Tin majority of the authors of the Special Memoirs have spent

their manuscript and illustrations for the press, without other remunera-,
