** The birds above enumerated were obtained by Mr. Dunn during 

 his residence at Canton. Some of them appear to have been im- 

 ported thither from Malacca, and the remainder form but a small 

 sample of the zoological treasures that might be obtained were the 

 Chinese Empire opened to naturalists. It seems strange that so 

 little has yet been done to obtain specimens of Chinese zoology 

 through the medium of the natives. Thousands of bird- skins are 

 annually sent to Europe by the natives of Brazil, Senegal and Ma- 

 lacca, and there can be no reason why a similar trade should not be 

 established with China. All that the Chinese want is a little instruc- 

 tion in the art of preserving specimens, which might be easily com- 

 municated if some of the merchants connected with the tea-trade 

 would take an interest in the subject." H. E. S.

March 30, 1843. — " Researches into the Structure and Develope- 

 ment of a newly discovered parasitic Animalcule of the Human 

 Skin, the Entozoon follicular um^ By Erasmus Wilson, Esq., Lec- 

 turer on Anatomy and Physiology at the Middlesex Hospital. 



While engaged in researches on the minute anatomy of the skin 

 and its subsidiary organs, and particularly on the microscopical com- 

 position of the sebaceous substance, the author learned that Dr. 

 Gustow Simon* of Berlin had discovered an animalcule which inha- 

 bits the hair follicles of the human integument, and of which a de- 

 scription was published in a memoir contained in the first Number 

 of Miiller's Archiv for 1842. Of this memoir the author gives a 

 translation at full length. He then states that, after careful search, 

 he at length succeeded in finding the parasitic animals in question, 

 and proceeded to investigate more fully and minutely than Dr. Simon 

 had done the details of their structure, and the circumstances of their 

 origin and developement. They exist in the sebaceous follicles of 

 almost every individual, but are found more especially in those per- 

 sons who possess a torpid skin ; they increase in number during 

 sickness, so as in general to be met with in great abundance after
