230 The Museum Gazette 



Trypanosoma is the name of the parasite introduced by it into the 

 blood of the victim ; but as it stands, your paragraph is misleading. 



(2) Page 158. — "When the moon comes between the earth and the 

 sun . . . . . the earth is eclipsed to the moon." Surely the very 

 narrow path of the moon's shadow on the earth does not justify the 

 use of the word " eclipse ? " We might almost as well say (though of 

 course the conditions are different) that Venus in its transit "eclipses 

 the sun ! " 



(3) Page 1 59. — As to the existence of life, air and water on the moon, 

 have you considered the evidence produced by Professor Pickering 

 (see Nature, vol. lxxi., page 226) ? Of course, it is not conclusive, but 

 it is very interesting, and coming from such an observer cannot be 

 ignored. Yours faithfully,

(1) We are obliged to our correspondent for the correction of the 

 misprint in reference to the Tsetse-fly. 



(2) As regards the eclipse of the earth, our expression was not 

 intended to imply completeness, but we gladly acknowledge that, as our 

 correspondent points out, it implied too much. 



(3) We had no wish to ignore Professor Pickering's most interest- 

 ing speculations, and may perhaps refer to them at a future time. 

 For the present we were content to record the generally accepted 

 facts.— Ed., M.G. 



TO THE EDITOR OF THE " MUSEUM GAZETTE." 



Dear Sir, — Thanks for the Museum Gazette, which I shall 

 have great pleasure in recommending to the " Scarborough Field 

 Naturalists' Society." I do not see how it is going to pay you at 

 Sixpence. It is so very difficult to get a paying number of subscribers 

 to any scientific journal. It was a good idea to do a series of seaside 

 issues. The shells are very good. Perhaps you might follow on with 

 some land and freshwater shells, especially as the autumn is the best 

 time for collecting — especially the terrestrial species. Sorry you have 

 so poor an opinion of Filey sands. They are good shell-collecting 

 ground — most beautiful fossils, ammonites and belernnites especially, 

 are to be got where the mud cliffs "merge into the chalk. 



13, Gladstone Road, Scarborough. Yours faithfully, 



August 25, 1906. W. Gyngell.
