70 NOTICES ON THE PUBLICATION OF THE “MONOGRAPHS” 
a fair copy of it, and at present I am very near the end of this 
task. The work will nearly fill a volume. The ‘Additions’ to 
the Trypetae , prepared long ago, might be added to it. This 
would furnish plenty of matter for Yol. III. But, how about its 
publication ? Do you still feel interested enough in this work 
to undertake the great burden (‘ die grosse Last ’) of translating 
it? Still less am I sure how I am standing with the Smithsonian 
Institution.” Loew complains about some remissness, on the 
part of the Institution, in the fulfilment of its engagements towards 
him, of an apparent want of appreciation of his work, etc., and 
ends by saying: — 
“ I want at least to know whether the Institution intends to con¬ 
tinue the publication of the ‘ Monographs,’ and whether I should 
consider myself authorized to order the necessary plates at its 
expense.” Loew had no reason whatever to doubt of my good 
will, nor of the interest taken in his work by the Smithsonian 
Institution. I referred his complaints to Professor Baird, who 
(March 16, 1866) gave me the necessary explanations and assur¬ 
ances, and added: “ As to the failure to send him a commendatory 
letter, remember the immense amount of the work we have to do, 
and the small force to do it with. We trusted to you as our confi¬ 
dential adviser to arrange all such matters with Loew, and trust 
you will do so, excusing our delay on account of the war, the fire, 
the flood, and anything else,” etc. 
Under the circumstances which I have just related it might 
have been expected that Yol. Ill would make its appearance 
soon. Nevertheless, more than eight years elapsed between the 
summer of 1865, when Loew told me that the manuscript of the 
Ortalidae was ready for publication, and December of 1873, when 
the third volume made its appearance before the public. 
What was the cause of Loew’s hesitation to publish a manu¬ 
script so far advanced in preparation as he announced it to be? 
Was he perhaps dissatisfied with its execution, but, at the same 
time, unwilling to acknowledge it? The fact is, that later he 
seems to have entirely rewritten it, and this was no doubt due to 
the mass of new material that I had sent him in the meantime 
(especially in Trypetae'). It would be useless and tedious to
