THE EFFECT OF CLIMATE UPON HEALTH AND DLSEASE. 451 



Appendix II. contains a list of Learned Societies and Institutions 

 which collect and publish information bearing upon a number of the 

 points enumerated herein. 



Those who have the opportunity of contributing to the general fund 

 of information which may prove useful in inquiries should consult the 

 ' Hints to Travellers ' of the Royal Geographical Society or the ' Admiralty 

 Manual of Scientific Inquiry,' and should be careful to communicate 

 the results of their investigations for publication in the most generally 

 accessible forms. 



For geographical conditions reference should be given to standard 

 books, papers, and maps, if such exist. If these are inadequate, supple- 

 mentary notes and maps should be forwarded.

Data relating to Disease, 

 (a) Nomenclature. 



The list of diseases given in tlie printed forms supplied for the record 

 of cases and deaths from disease is based on the official ' Nomenclature 

 of Diseases ' of the Royal College of Physicians, edition 1906. Where 

 an observer is not in possession of, or has not access to, this ' Nomen- 

 clature,' he will be provided with a copy on application to the Central 

 Committee. 



Those diseases only have been printed in the forms which appeared 

 for one reason or another to lend themselves to the purposes of this 

 investigation, or concerning which fuller information as to distribution 

 and prevalence is desirable, whicli should be obtainable without difficulty 

 in the course of this inquiry. 



Synonyms have been inserted in most cases in which they are used 

 in the ' Nomenclature,' and in all in which any doubt could arise as 

 to the exact nature of the disease designated by the official title. The 

 number prefixed to each disease is that allotted to it in the ' Nomen- 

 clature,' and a reference will therefore clear up any difficulties of 

 description. 



But the printed list is not intended to be exclusive ; space is left at 

 the end of the list under each system for the insertion in manuscript of 

 any other disease which an observer is prepared to report on, and in fact 

 certain systems have been allotted space for this purpose, though no 

 diseases have been printed under the headings. 



The names of symptoms or of local manifestations should not be used 

 as descriptions ; the case should be inserted under the general heading of 

 the cause to which these conditions are due. In the special case of 

 anaemia (No. 61), included in this list for purposes of comparison, this 

 term should only be used where it has pi-oved impossible either to 

 differentiate the type or to discover the cause. 



While it is highly desirable that the officially recognised titles should 

 be used for the disease under report in oi-der that all doubt and difficulty 

 may be removed, yet where the observer either has not access to the completo 

 list or for some reason finds it unsuitable, there is, of course, no objection 

 to his using any terminology that may appear to him satisfactory, pro- 

 vided always that it is used consistently, and that Iio gives such
