Dear Martin, 
Now that the duet is "beginning to settle I can 
Price again take up my corresoo ndence where I left it more 
than si T months ago. I must admit that X c m rs ucier not i ified 
to fina your letter of January still unanswered and I will 
try now to rectify this error though you may have lost interest, 
or at least given uo hope of get tin ' a reply . ^In tae 
accomoanying sheets which you nay os sole to read, I hs\e 
tried to answer your questions about Hfhich postures occur 
in which situations and which calls usually accompany them. 
I don’t sun ose it will he satisfactory for you - °t>oer people s 
re olies never are - hut It may give you some clue of the 
way I think things are. I trust that my nomenclature of the 
postures hasn’t changed too drastically since I last wrote 
to you. I have regretful lyx abandoned "stretch ^ in favour 
of "erect" on the grounds that Palmer has used tnis name 
and ■furthermore that Baer ends et al. in tne Black Tern 
pa per have also voted for it. "Slant" is an extremely 
unsatisfactory name for the rather vague posture wnich it 
describes hut I haven’t hen ablefto invent a better, and I am 
afraid it may have to stick.
