PEEFACE 



This work was undertaken at the suggestion of the late Professor Roland 

 Thaxter while the writer was a member of the faculty of Harvard University. 

 After a preliminary survey of the literature, a course in Medical Mycology 

 was offered in 1924 and the book has grown out of that course. The manu- 

 script was completed in February, 1932, but unavoidable delays in publishing 

 have prevented its earlier appearance, though it has been used by my classes 

 and research students for several years and has frequently been revised. It 

 contains a summary of all the literature in this field to the end of 1933 except 

 for a few scattered references in relatively rare periodicals which are marked 

 by asterisks in the bibliographies at the ends of the chapters. I have also 

 included all of the references available to me up to July 1, 1934, either at the 

 library of our own Medical School or in the Boston Medical Library, but 

 probably important papers in this period have been missed, as many titles 

 had not found their place in abstracting and indexing journals ; work in my 

 own laboratory during this period has been incorporated, even though the 

 papers resulting from the work have not yet been published. During the 

 correction of proofs I do not intend to include any references unless new 

 names or combinations proposed in them affect the nomenclature of species 

 I have already recognized. 



For the first time in this field, a relatively complete and accurate bibli- 

 ography of existing literature is presented. In such a large bibliography, the 

 abbreviation of names of journals presents a serious problem. The code of the 

 Leagaie of Nations* was received too late to be followed. If the abbreviation be 

 too brief, it may cause ambiguity to one who is not well acquainted with the 

 journals of a given country or of a given subject, especially when journals have 

 similar names. For example, Arch. Derm, might refer to Archives of Derma- 

 tology and Syphilology, Archiv fur Dermatologie und Syphilis or Archivio 

 Italiano di Dermatologia e Sifilologia. When Ann. is confused with Arch., as 

 is regularly done bj'' the writer of one text in this field, we have also to consider 

 Annales de Dermatologie et de Syphiligraphie and the Anales Dermatologicas 

 y Sifiliograficas. More rarely we have several journals with the same name, 

 when it is desirable to add the name of the editor, especially if the journals 

 are contemporary. For example, the abbreviation Jour. Bot. is almost mean- 

 ingless. It might refer to the Journal fur die Botanik, Journal de Botanique 

 (Desvaux), Journal de Botanique (Morot), Journal of Botany (Hooker) or 

 Journal of Botany, British and Foreign (edited successively by Seemann, 

 Triemen, Britten and Rendle, and sometimes cited as Seemann' s Jour., etc. In 

 cases where the usual abbreviation would indicate a journal only by the
