 order to give considerations of the main characteristics of the different 

 kinds of Nematode worms mentioned, with the figures of them in 

 different stages, together for convenience of comparison.

The following note, with which I was favoured on Dec. 17th, by 

 Mr. Samuel Hall, of 3, St. Andrew's Place, Cardiff, is of especial 

 interest as an observation of warble-maggots being found at one time 

 (in the latter part of February) to the amount of at least forty on a 

 mare in his possession. So far as I am aware from observations sent 

 me, or from record, it is very unusual in case of Horse Warble attack 

 to find more than a very few maggots on one animal ; for the most 

 part there appears to be only one, and I have never had notes of more 

 than three maggots at one time being observed. 



In 1886, the only year in which I have had more than a few cases 

 reported of this attack, Mr. Strattou, of The Duffryn, Newport, Mon., 

 mentioned, " You seldom find more than one on a horse, and that one 

 is sometimes not on the back" ; and Mr. Hy. Thompson, M.R.C.V.S., 

 of Aspatria, Cumberland, writing about the extensive diffused swelling 

 caused at the neck of a horse then under his care for presence of 

 warble-maggot, observed regarding the specimen he sent me, "This is 

 the third from the same animal, which is very peculiar, as you seldom 

 see them." 



During the past season a very few notes of Horse Warble were 

 sent me, but none adding to our previous amount of information, 

 until Mr. Hall favoured me with the following remarks : — 



"I thought it might be of interest to you to know that I had a 

 mare this year with a great number of warbles on her shoulders, back, 

 and quarters. I bought her at Cardigan last J anuary ; she had been 

 kept out of doors till about a fortnight before I bought her, and was 

 very low in condition ; at that time there were none observable, but 

 about the middle or end of February she had at least forty, so that it 

 was difficult to put a saddle or harness on her. Many of them my 

 man squeezed out ; but on those not so advanced, I applied a small
