SPECIAL REPORT ON THE COLLECTION 
candor, if lie had been, in this respect, more like Dr. Hagen, we 
should have reached the same result, or perhaps more, but, at least 
for me, with less friction. 
My principal motive for drawing up this long account of my 
relations with Loew, and of my scheme to form, for future use, a 
collection of the original types of North American Diptera, was the 
intrinsic interest which attaches to the matter. I confidently hope 
that, besides the biographical and psychological features connected 
with my story, the details it contains will be of some use to those 
who may have occasion to consult the collection in future. The 
desire to do justice to myself, legitimate as it is, would not have 
alone prompted me to undertake this somewhat tedious task.

Before having the collection removed from Loew’s dwelling and 
boxed up, I collated all species contained in it with my manuscript 
Catalogue, which I had brought with me. The specimens which 
had been temporarily removed to other boxes and drawers were put 
back wLere they belonged. I found that, on the whole, the collec¬ 
tion was remarkably complete and in good order. Some few of 
Loew’s descriptions had been made from specimens borrowed from 
other collections, and those, of course, were not present. Very few 
types were wanting for other reasons; for instance, from the acci¬ 
dental loss of a label, or on account of the destruction of the origi¬ 
nal specimen. The type-specimens were provided with labels in 
Loew’s own handwriting fastened on the pin; the others were 
placed alongside of them, or behind them, in a second row. Spe¬ 
cific names alone are marked on the labels; the generic names are

cially at the end, to suit present circumstance and to make it more intelligible. If I 
publish all the minutiae about labels, localities, original discoverers of the species, etc., 
it is because I am convinced that they are not useless.
